Teensy 4.0 USBHost_t36 - Won't Recognize USB Hub

grub · Jun 24, 2022

Hello! I tried to look through all the other forum posts about this before creating another of my own, but I haven't been able to solve my issue. I am making a MIDI USB Host like this one https://little-scale.blogspot.com/2021/04/midi-usb-host-to-and-from-midi-5-pin.html. The only difference is I'm using a Teensy 4.0. I'm trying to connect a Novation Launch Control XL and Launchkey Mini through this hub: https://www.amazon.com/dp/B00BWF5U0M?psc=1&ref=ppx_yo2ov_dt_b_product_details. Both controllers work fine when connected to the Teensy USB Host port without the hub. But with the hub it's not working properly, it's only passing power. When I run the HIDDeviceInfo example project I am able to see the information of the 2 controllers when they are plugged in individually (without the hub), but there is no information when the USB Hub is plugged in. I have tested the USB hub with my Macbook Pro and it works as it should. I'm a beginner when it comes to code so I could be missing something obvious. I tried running the other MIDI examples projects where there are more hubs and devices setup, but the hub isn't recognized with those projects either. Thanks in advance for any help!

Arduino 1.8.19
Teensyduino 1.56
MacOS Mojave

Code:

#include <MIDI.h>        // access to serial (5 pin DIN) MIDI
#include <USBHost_t36.h> // access to USB MIDI devices (plugged into 2nd USB port)

MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI1);

USBHost myusb;
USBHub hub1(myusb);

MIDIDevice midi01(myusb);

elapsedMillis ledOnMillis;

void setup() {
  pinMode(13, OUTPUT); // LED pin
  digitalWrite(13, LOW);
  MIDI1.begin(MIDI_CHANNEL_OMNI);

  delay(1500);
  delay(10);
  myusb.begin();
}

void loop() {
  bool activity = false;

  if (MIDI1.read()) { // 5 pin DIN to USB Host
    sendToHost(MIDI1.getType(), MIDI1.getData1(), MIDI1.getData2(), MIDI1.getChannel(), MIDI1.getSysExArray());
    activity = true;
  }

  if (midi01.read()) { // USB Host to 5 pin DIN
    uint8_t type =       midi01.getType();
    uint8_t data1 =      midi01.getData1();
    uint8_t data2 =      midi01.getData2();
    uint8_t channel =    midi01.getChannel();
    const uint8_t *sys = midi01.getSysExArray();
    sendToMIDI(type, data1, data2, channel, sys);

    activity = true;
  }

  if (activity) {
    digitalWriteFast(13, HIGH); // LED on
    ledOnMillis = 0;
  }
  if (ledOnMillis > 15) {
    digitalWriteFast(13, LOW);  // LED off
  }

}

void sendToMIDI(byte type, byte data1, byte data2, byte channel, const uint8_t *sysexarray)
{
  if (type != midi::SystemExclusive) {
    MIDI1.send(type, data1, data2, channel);
  } else {
    unsigned int SysExLength = data1 + data2 * 256;
    MIDI1.sendSysEx(SysExLength, sysexarray, true);
  }
}

void sendToHost(byte type, byte data1, byte data2, byte channel, const uint8_t *sysexarray)
{
  if (type != midi::SystemExclusive) {
    midi01.send(type, data1, data2, channel);
  } else {
    unsigned int SysExLength = data1 + data2 * 256;
    midi01.sendSysEx(SysExLength, sysexarray, true);
  }
}

That looks to be an unpowered hub?

With T_4.0 connection wires had to be soldered to the bottom Host D+ and D- pins, those lines have to be done well. Good sign both devices work individually.

The T_4.0 unlike the T_4.1 doesn't have an onboard current control chip and the hub and device(s) may be stunning the T_4.0?
Without external power beyond the computer the power is limited to and through the Teensy.

Using a powered hub may give better results.
There is a DEBUG #define under comment in the Host.c file that will provide generous Serial output of any events as they happen. Enabling that may show signs of activity.

PaulStoffregen · Jun 24, 2022

Two quick things to try...

1: replace MIDIDevice with MIDIDevice_BigBuffer.

2: edit ehci.cpp to uncomment this line:

Code:

        //USBHS_PORTSC1 |= USBHS_PORTSC_PFSC; // force 12 Mbit/sec

To be honest, I'm skeptical either of these will make a difference. But they're easy to try, so I'm hoping you can check whether the buffer size or USB high speed mode are a factor before I order this particular USB hub and put this on the list of issues to investigate.

KurtE · Jun 24, 2022

The Amazon page said I ordered one of these 5 years ago... Don't remember it, but will look around and see if I find it

grub · Jun 24, 2022

@ Paul Thank you for the quick response! I tried both of those things and it did not make a difference.

@defragster Is the debug you're referring to #define USBHOST_PRINT_DEBUG in the USBHost_t36.h file?

Yes, sorry - indeed, in that .h file : ...\USBHost_t36\USBHost_t36.h

Code:

// Uncomment this line to see lots of debugging info!
//#define USBHOST_PRINT_DEBUG

grub · Jun 24, 2022

I uncommented that out, but after doing so I don't see anything in the Serial Monitor when I'm running my original program. I'm not too familiar with this process, I'm assuming where the debug information would be is in the Serial Monitor, is that correct?

PaulStoffregen · Jun 24, 2022

I ordered this hub today. Or really, Robin did

KurtE · Jun 24, 2022

I also have one on order... I found the other hub, that I ordered back then

Yes, that part of p#2was correct: "will provide generous Serial output of any events as they happen"

With that enabled, remove the HUB and try a device individually and that should then show since the device connects in that case.

grub · Jun 24, 2022

I’m excited to see what you guys find out about this hub. Thanks for the help and interest in my issue!

KurtE · Jun 25, 2022

Just an FYI - This hub has been mentioned before as working back in 2017 in the thread:
https://forum.pjrc.com/threads/4250...atency-on-Win7?p=135868&viewfull=1#post135868

And there was talk about Multi-TT...

grub · Jul 5, 2022

I looked through that thread and it’s talking about using the USB Hub to connect the Teensy to a PC. I’m trying to use mine standalone, not connected to PC. Sorry if I’m not understanding what’s being discussed in that thread correctly. So has this been tested as working in the same way I’m using it? Connected to the Teensy’s USB Host port?

KurtE · Jul 5, 2022

Yes some/most of that may have been mentioning about The teensy was plugged into one of these. But I mentioned it because maybe Paul had one around... Or maybe more information in the thread about the hub that might give some indication.

Note: My new one did arrive, and for example I ran it connected to the USB Host on a Teensy MicroMod running the Mouse USBHost example sketch.

And so far everything appears to be working.

Note: I don't have a midi, so can not test that part...

On your test case, have you tried adding another HUB object to your sketch:
USBHub hub2(myusb);

And see if that helps.
The reason I suggest that is some devices have a built in USB Hub. I have a few keyboards that are built that way. And if there is not a HUB object available, it won't then talk to the actual device, in my case a keyboard.

KurtE · Aug 17, 2022

Paul,

I am not sure if you had a chance to play with this HUB yet?

But I am getting a good HANG with this one. It depends on order of when devices are added.

Trying to debug Logictech G Pro Mouse with keyboard (other thread)
https://forum.pjrc.com/threads/6925...yboard-Problem?p=311207&viewfull=1#post311207

Now if I start up a test sketch (Posted in other thread)

If I start up the sketch with lets say all of the usb ports turned off.

If I startup keyboard first and then Wireless receiver it appears to work ok.

If however, I startup the wireless receiver first and then keyboard will totally hang. I turned on the USBHost_t36 debug stuff, and uncommented lots of stuff in ehci...

We are getting chains in the loop. The loop detection code on printing was not finding it and infinite print. So, I hacked it up to look for any loops as it was not looping back to start:

Code:

void USBHost::print_qh_list(const Pipe_t *list)
{
	if (!list) {
		USBHDBGSerial.println("(empty)");
		return;
	}
	const Pipe_t *node = list;
	uint8_t max_print = 32; // max number of items..
	while (1) {
		USBHDBGSerial.print((uint32_t)node, HEX);
		const Pipe_t *next_node = (const Pipe_t *)(node->qh.horizontal_link & 0xFFFFFFE0);
		if (!next_node) break;
		// Lets check for loops
		const Pipe_t *nt = list;
		while (nt != node) {
			if (nt == next_node) break;
			nt = (const Pipe_t *)(nt->qh.horizontal_link & 0xFFFFFFE0);
		}

		if (nt != node) {
			USBHDBGSerial.print(" -> (loops) ");
			USBHDBGSerial.print((uint32_t)next_node, HEX);
			break;
		}	
		node = next_node;

		if (!max_print--) {
			USBHDBGSerial.print(" (Probable Loop)");
			break;
		}
		USBHDBGSerial.print(" -> ");
	}
	USBHDBGSerial.println();
}

A run that hung...

I am not sure if you had a chance to play with this HUB yet?

Nope, not yet. It's been sitting on my desk, still inside the original box.

We're just today catching up to backlog of Teensy 4.0 orders (mostly for distributors) but I have a huge pile of stuff on my workbench. Should I move this hub up in priority?

KurtE · Aug 17, 2022

As for priority hard to say... It may not be fully related to this hub... But simply order of what things stings startup in what order

I will try to take a look on why when it Starts in certain order it ends up ending up with all looped QH... Almost like it is adding the same item twice.

That is an area of the USBHost stuff, that I probably need to learn better.

Another other interesting USBHost_t36 host thing with a Tablet that @mjs513 has that for example reports a different VID/PID on T4.x than it does on T3.6 or Windows/Linus/RPI.
https://forum.pjrc.com/threads/70855-USBHost-not-identify-Device-PID-VID-but-Rather-a-USB-VID-PID

I think it is some form of composite device? Whatever that means.
We see it as:

Code:

Device Descriptor:

    Class/Subclass/Protocol = 0 / 0 / 0
    Number of Configurations = 1
enumeration:

Manufacturer: Nuvoton

Others see it as a different ID... And T3.6 goes through both:
Extracted from the other thread:

Code:

Paul and all,

On the HUB and the like... I don't have the MIDI, but running into the issue as mentioned in the other thread mentioned in #16

But I wonder if it may be related to the earlier in the posting above, when
the Mouse Wireless controller is detected and devices claimed, and the like:
The Wireless controller appears to be setup to handle both a Mouse and a Keyboard, but the one I purchased has no keyboard.
But it will claim one. At the end of it with USBHost Debug turned on, we see an ERROR Followup message.

I have turned on more debug stuff and hacked in some additional debug output.

Code:

    20006520  Followup 20006520    token=88180

The Async follow up list was NULL, so nothing happened here.
Some of the last is garbage, there was a TODO to handle periodic, so thought I would at least do quick and dirty print out the list.

So then went back and looked at the Keyboard callback stuff:

The Token is 88150:the 0x8000 bit was set so Completed and as such we do the callback with the data shown:
But if I am looking correctly, the low byte is status? 0x50 so bits 4 and 6 (Halted, Babble) ?

Again, not sure if this is related to the creation of loops in the linked list?
Where it looked like we were adding the same QTD that already existed in the list.

PaulStoffregen · Aug 25, 2022

Ok, I have it on my workbench now with 1 USB MIDI device. So far I'm not seeing anything wrong.

I added this so I can see the incoming MIDI messages as I turn the knobs or touch the drum pads.

Code:

  if (midi01.read()) { // USB Host to 5 pin DIN
    uint8_t type =       midi01.getType();
    uint8_t data1 =      midi01.getData1();
    uint8_t data2 =      midi01.getData2();
    uint8_t channel =    midi01.getChannel();
    const uint8_t *sys = midi01.getSysExArray();
    [COLOR="#FF0000"]Serial.printf("USB MIDI: %02x %02x %02x\n", type, data1, data2);[/COLOR]
    sendToMIDI(type, data1, data2, channel, sys);

    activity = true;
  }

Everything seems to work fine.

Do I need to plug multiple devices into the hub? Or any suggestions on other things I should try to reproduce the problem?

KurtE · Aug 25, 2022

When I have been able to cause the issues in previous posts, it took at least two things plugged in.

I was doing with Mouse and keyboard. And it appeared like what those devices were and maybe order they were enumerated mattered.
And not sure but maybe which slots.

For example, I had the Logitech G Super light wireless controller plugged into the 3rd slot. Where first is the one nearest the wire.
I had a keyboard plugged into the 1st or 2nd slot. (I actually had two keyboards plugged in) where 1st was Gigabyte (another problem child) and 2nd some simple Dell keyboard.

I would reproduce the issue by first turning on the power or starting up with power on the logitech wireless mouse.
Again, Mouse controller has both Mouse and Keyboard, Note I did not buy mine with keyboard. Keyboard was sending 64 byte messages.

Then I would turn on one of the keyboards and system dead. Post #16 shows full debug where when the keyboard was created it ended up creating loops.

I changed the printing of loop detecting slightly as the loops was not back to the start of the list, but back to 2nd item.
