USBHost_T36, hosting USB MIDI devices with virtual cables (ports)?

I'm trying to confirm if Teensy 3.6 can host USB Midi devices that have more than one virtual MIDI cable, and if so how to tell how many ports a given device has. I believe this bolded modification to the 16x16 example code will return the virtual cable:

Code: 
  // Next read messages arriving from the (up to) 10 USB devices plugged into the USB Host port
  for (int port=0; port < 10; port++) {
    if (midilist[port]->read()) {
      uint8_t type =       midilist[port]->getType();
      uint8_t data1 =      midilist[port]->getData1();
      uint8_t data2 =      midilist[port]->getData2();
      uint8_t channel =    midilist[port]->getChannel();
      const uint8_t *sys = midilist[port]->getSysExArray();
      sendToComputer(type, data1, data2, channel, sys, 6 + port);
      [b]uint8_t cable =      midilist[port]->getCable();   // should return the virtual cable of this device[/b]
      activity = true;
    }
  }

Is there a limitation to the number of virtual cables that a hosted USB MIDI device can have? 16? And how can I identify how many virtual cables a device has when it is connected?

Also, in the 16x16 example there are 10 hosted USB MIDI devices. Is this the max number or could you host more? If I connected (16) Teensy 3.6 devices, all set to 16x16 Midi mode, to a master Teensy 3.6 with USB hubs, would I have a 64x64 matrix?

And finally, I've found some manufacturer's don't assign serial numbers to their MIDI devices. For instance the Akai LPK25 keyboard controller. If I had two of these, and connected them to the host port on a teensy 3.6, would there be a way to differentiate between the two and recognize which is which when they are disconnected and reconnected?

Very impressed and grateful for all the hard work and open source code provided by Paul for this product.
 
Wow, so many questions. Here's quick answers...

Yes, confirmed.

You don't.

Yes, 16.

This limit comes from the USB MIDI spec which dedicates 4 bits to the virtual cable number, so it really can not be increased beyond 16.


And how can I identify how many virtual cables a device has when it is connected?

Ideally there should be a way to ask for this info, but it's currently not supported by the library. Unless you add code to parse the descriptors, you can't find out from the library how many virtual cables each device claims it supports. Nor can you query any of the other parameters from the audio class descriptors. The library just don't (yet) give you any way to ask for that info.


Also, in the 16x16 example there are 10 hosted USB MIDI devices. Is this the max number or could you host more?

USBHost_t36 is designed around the idea that you put instances in your program for each device that might connect. So if you put more than 10 instances of the MIDIDevice object, you could have more than 10.

At some point of course there are practical limits, memory, bandwidth, CPU time to keep up with so many messages. Almost no work has been done so far to really explore or test those limits, so I really don't have any solid guidance on how far you can push this.


If I connected (16) Teensy 3.6 devices, all set to 16x16 Midi mode, to a master Teensy 3.6 with USB hubs, would I have a 64x64 matrix?

Don't know what's meant by "matrix" in this question.

As a USB device, Teensy 3.x offers "MIDIx16" meaning 16 virtual cables. There isn't any mode called "16x16" (though there are examples using this name), so again I don't quite understand your question.

Theoretically, you could connect 16 Teensy 3.6 boards, each running MIDIx16, of course using USB hubs. Don't forget to include enough USBHub objects. Remember that most large hubs on the market are actually 2-tier networks of 4 port hubs, so for example you would probably need 3 of those USBHub objects in your code to support a typical 10 port hub.

If you do build this and make it actually do something with so many virtual cables, I hope you'll share photos!


And finally, I've found some manufacturer's don't assign serial numbers to their MIDI devices. For instance the Akai LPK25 keyboard controller.

Sadly, no. Regular computers face exactly the same issue with identical USB devices.
 
One further point, regarding USB bandwidth. USB has 4 transfer types, called "control", "bulk", "interrupt" and "isochronous", which have different ways of the USB host allocating the USB bandwidth. The device chooses which transfer type, the host is responsible for actually managing the bandwidth.

USB MIDI allows use of either "bulk" or "interrupt". Almost all USB MIDI devices are designed with bulk protocol endpoints.. When you choose any of the MIDI device options in Tools > USB Type, Teensy always uses USB bulk protocol for USB MIDI.

However, some devices on the market do use "interrupt" type. Novation Launchpad is the one which comes to mind.

With interrupt type, a portion of the USB bandwidth is reserved. As you connect more of these devices, the reservation grows. USBHost_t36 uses a fairly simple strategy for reserved bandwidth, which is only able to reserve a little over half of all the bandwidth for interrupt protocol pipes. EHCI has a feature calls frame span traversal nodes which allows reserving more, but USBHost_t36 does not support that feature. It's very complicated, but allows 80% instead of ~50% of the bandwidth to be allocated. If you connect a very large number of devices needing interrupt pipes, eventually (around 50%) there won't be any more guaranteed bandwidth.

The interrupt bandwidth guarantee is a theoretical calculation based on the worst possible case. But if the guarantee can't be made for the very worst case, USBHost_t36 will not recognize the device if it uses interrupt protocol pipes and all the guarantee-able bandwidth has already been promised to other devices. It doesn't matter if all the devices would still be able to work under that actual bandwidth usage scenario... the interrupt pipe bandwidth gaurantee is an absolute hard promise for certain bandwidth under the very worse possible scenario. If the promise can't be made, the device doesn't finish enumeration and can't be used.

With bulk protocol, there are not promises on bandwidth. All bulk devices share all the available bandwidth, after the reserved devices have their option to use (or leave used) their guaranteed bandwidth. You can keep plugging in more bulk devices without worrying if they'll be rejected because bandwidth can't be promised.

With both bulk and interrupt, if the device doesn't actually transmit or receive data, the rest of the pipes are able to use that bandwidth. But how well a large number of slower-than-480 USB devices share all the bandwidth depends on the type of hubs you use. USB 2.0 hubs (and the USB2 portion of USB3 hubs) come in 2 types: (cheap) Single-TT and (good) Multi-TT. Only the Multi-TT type hubs allow all their downstream 12 Mbit/sec devices to truly share the upstream 480 Mbit/sec connection. Most people never notice the difference, but if you really are connecting a very large number of 12 Mbit/sec USB devices and you expect many of them to push bandwidth limits, you really do need the better quality Mulit-TT type hubs to avoid bandwidth bottleneck problems.

Fantastic response, thank you.

Apologies for confusion, when I said 16x16 I meant MIDIx16.

I’ve never seen a hub advertised as single or multi TT, do you know of some on the market? Is there a way to query this from the library when you create the USB Hub objects? Can you read from the library if a device is bulk or interrupt, and is there any way to monitor the feedback reservations?

If I create a HID Keyboard instance will it play nicely with the MIDI instances?

The USB Host port on my teensy 3.6 is reading 3.6v (coincidence?) on the 5V supply pin, not sure what I did as it was working for a while but I’ll need to order a new one before I can begin testing the new USB Host code. I’ll be sure to share pictures and code for the project as it develops, and of course questions.

Thanks again Paul, your fast and thorough response is much appreciated.

Here's a photo of some I tested.

Scroll down to "Large System Guidelines".

Yes, it is very sad that the most meaningful non-power technical spec about USB hubs is almost never mentioned in the sales info for hardly any hubs. Consumer electronics is bizarre like that.

No.

No, there's no API for that either.

Is USBHost_t36 actually running?

Something may be wrong if it is. But if the TPD3S014 switch is turned off, it's default state, then you would see little or no voltage.
 
Simplest is to just plug hubs into Linux or Windows 10 and check. Usually in any batch of random hubs of different make/model, some will turn out to be Multi-TT protocol.

Edit: that little 2-port one which led to the discovery of a bug deep in the USB stack was also a Multi-TT type. Here's an article I wrote about that adventure in bug hunting.

https://www.pjrc.com/usb-hub-bug-hunting-lessons-learned/

Here's the forum thread about that hub

https://www.pjrc.com/usb-hub-bug-hunting-lessons-learned/

Sadly, clicking in the link to Amazon on that thread shows it's no longer available.
 
How do you check a hub in Linux? If it’s a terminal command I can try it in OSX.

Here’s another question, it would seem that usb midi devices with multiple virtual cables can report a name for each cable. Here’s a screenshot from Ableton Live (ignore the highlights that aren’t mine), notice Virus TI, Akai MPK49, and microlite are all single devices reporting multiple virtual cables, each with a unique name (ie Virus MIDI and Virus Synth)

http://ultimateoutsider.com/blogimages/blofeldvirtualeditor/blofeldlive02.png

Is it possible to get these virtual cable names from the library? When using a teensy running MIDIx16, could we name the virtual cables that the computer sees?
 
I’ll do this tonight when I’m back in the studio and share the results here. Maybe this will shed some light on the virtual cable names as well, I’ll leave all the synths and midi devices connected.
 
On Macintosh, the similar command line utility is "ioreg -l", but it's output is all devices not nearly as easy to use as the Linux one.

Apple has a utility called "USB Prober". It used to come with X-Code. I'm not sure how to get it now. But here's a screenshot of how it shows the hub protocol.

screen.jpg
 
Looks like it comes with the developer packages, I’ll try to dig it up, or I could use my windows laptop if that’s easier.
 
Well after following the instructions here I was able to download USB Prober. Raw output is too big for this post, so I'll post it separately.

Here's a screenshot:
VvBlnA4.jpg

I have 3 usb hubs, the one that came up as MTT is the cheapest of the bunch! You can find them at newegg for $8 here.

The two listed as "Genesys Logic" are actually a single 7 port D-Link hub.

Drilling down into the names of the virtual cables. The "Virus TI" has two virtual cables that show up in Ableton live, one is "MIDI" which goes connects to the DIN ports, and one is "SYNTH" which controls the synth. Here's what it looks like in audio midi setup:

sMfzwr4.jpg

I'm searching the output of USB Prober for "Synth" in hex and it's nowhere to be found. The synth is also an USB audio interface with hardware inputs and outputs, as well as audio into the vocoder. Looking at the listed interfaces, #3 and #4 are likely the virtual MIDI Cables. I don't see where the labels are coming from though.

Any ideas?

Just as a followup, I now believe that the names of the ports/virtual cables in these devices come from manufacturer drivers. Turns out these aren't class compliant MIDI devices, so I don't believe that there will be a way to read the port names (or even access the MIDI data streams).

Wow, so many questions. Here's quick answers...




Yes, confirmed.

I see you are confirming that USBHost_t36 can handle devices with several (virtual cables/ports), but by looking at the library I cannot figure out how to send a midi event (NoteOn) to a specific cable on the only MIDI device. Any clue would be helpful... Need to read from midi1.cable/port 0 and send to midi1.cable/port 1,

Thanks!
 
Sorry! Found it!

Saw that all midi commands could take cable as last argumnt (but default to 0)

Line 1072: void sendNoteOff(uint8_t note, uint8_t velocity, uint8_t channel, uint8_t cable=0) {
Line 1075: void sendNoteOn(uint8_t note, uint8_t velocity, uint8_t channel, uint8_t cable=0) {
Line 1172: void send(uint8_t type, uint8_t data1, uint8_t data2, uint8_t channel, uint8_t cable=0) {

...for example
 
Hey! Sorry for pulling out this old thread.
As I am having issues with USB Devices receiving MIDI on cables, they don't support, I needed a solution for it, and found this thread.
The Elektron Digitone, that only supports one Cables showed some weird behavior with my sequencer sending Clock to 4 cables. Instead of ignoring data on cables, it does not support, it seemed to parse them all. When I send a Midi Clock to cable 0 or to cable 0 and cable 1, everything is fine. When I send clock signal to 3 cables, Digitone showed doubled tempo...

After I already digged into the USBHost_t36 library and the USB MIDI1.0 and USB Audio documentation before, to see, how all this usb magic looks like, I went into it again today and found the solution:
Descriptor Type 0x25 (CS_ENDPOINT), described in midi 1.0, 6.22, page 26, sends a field named bNumEmbMIDIJack as the 4th byte. As 0x25 is recognized in the library but nothing is done here, I printed out the values I receive here, and it seems, that this is exactly, what we need. The number sent here, represents the number of cables of all the devices I own, that are usb midi compliant. I also tested it with another teensy and different USB_MIDI options. The number sent in this byte always represented what I expected and matched the number of "Devices" shown up on my Mac.
So I enhanced the USBHost_t36 library, storing that info into a variable and made it accessible in the MidiDeviceBase, and am now able to check on the device itself, if I can sent data to that cable or not.

Maybe Paul likes to add those 3 lines of code to the library, so others might use that info too, without having to patch the library themselfs?
