USBHost midi questions

[NotoYota]

Hi,
thanks again on so much effort that went into these products. Much appreciated.

I am experimenting with MIDI.
I would like to see if i can make my Teensy the central HUB of my MIDI setup. Doing some midi-routing, and filtering/translating messages. Maybe even add some Arpeggio or step-sequencer capabilities.
I have an Arturia Keystep connected via USB which works great.
I have an Behringer BCR-2000 connected via USB working great.

I have a hardware midi output on Hardware Serial 1 to a Dave Smith Mopho working great.

Two devices that i can't get to work are both M-Audio. An really oldskool M-Audio Oxygen 8 and an M-Audio MIDIMAN 2x2 interface (http://m-audio.com/products/view/midisport-2x2-anniversary-edition).
I have everything connected through some dumb USB-Hub. So even the devices that ARE working connect through same hub. So i don't think the hub is the issue.

I am using the Midi 16x16 example to do the tests.
Is there some way to enumerate the connected usb midi devices and to which midi "port" they are connected? So in the example code there is an number of "ports" called midi01 through midi10.
They are combined in this array midilist.
So can i detect and send text to the serial monitor what device is connected to what "port"

Also, both these m-audio devices present themselves as a multi-port interface to a computer. Is this supported in the usbhost midi implementation of Teensy?

Last question: In the USBHost library i see the option of printing debug messages. How can i turn this on?
i added #define USBHOST_PRINT_DEBUG 1 to the beginning of my sketch, but it doesn't seem to do anything.

Thanks a lot!

Patrick

Here are attached some visual clues.
Any help would be much appreciated.

It seems those M-Audio products just aren't detected as midi devices. But they are very important for my setup to be what i want it to be.
Also according to the website of M-Audio, at least the Midisport 2x2 interface should be class complient.

Try editing USBHost_t36.h. Look for this line to uncomment.

//#define USBHOST_PRINT_DEBUG

This will cause lots of info to print to the serial monitor. Copy & paste is all here. Buried in there will be this device's descriptors and (hopefully) some info that will help us figure out why the host midi driver didn't claim the interface.

 

[NotoYota]

thanks for your reply. So defining this in the sketch is not working ok, clear.

Here is the output with only the M-Audio midisport 2x2 connected to the hub:

Looks like it's getting hung up in the hub driver, never actually getting to the M-Audio device.

Which hub is that? (what exactly should I buy if I try to test it here)

Any chance you can test with a different hub?

 

[NotoYota]

The hub itself was a cheap brandless thing I got around lying around. According to the vendorid and productid it's an Atmel 4 port hub chip.

But the weird thing is the Arturia Keystep and Behringer BCR2000 works great on the same hub. Also tried several port combinations to rule out a faulty port.

I can see if I can test with a different hub. But it will be difficult-ish. Since I did not have a usb host connector and soldered wires of this hub directly to the teensy.

 

[NotoYota]

So, new clues

I have made a new host-cable so i can plug in and out different USB stuff.
The M-Audio midisport 2x2 on it's own was working.
But with the HUB it was not. With another HUB bus-powered it was also not working, but with that hub powered externally it DOES work.
So it seems to be some power-drainage issue which i assume influences the communication. Normally when i connect something to my mac that is using too much power it complains. But in this case it did not complain. Also the lights of the devices (including the M-Audio midisport 2x2) were lit.

The M-Audio Oxygen 8 is still not working. Not on it's own, Not on the new hub powered or not powered.

Here is the debug output with only the Oxygen 8 connected to the powered hub:
