T3.6/T4.x USB Host Serial and maybe Serial Emulation...

**KurtE** · 12-19-2020, 07:54 PM

[ Sort of place holder - will fill in more details later ]

The USBHost_t36 library works on T3.6 as well as T4 and T4.1

The library has support for several different USB USB devices like: FTDI, PL2303, CH341 as well as devices like other Teensy boards...

Would be good if I filled in details like which adapters we have tried...

Currently in the process of maybe also support the Teensy Serial Emulator HID class, as I am trying to debug a T4.1 with MTP USB type where it's debug data goes out through the SEREMU interface.

Again more details later.

Quick note: the SEREMU code is starting to work The code is currently up in the fork/branch: https://github.com/KurtE/USBHost_t36/tree/mtp_seremu

The test sketch for debug of MTP stuff has it's main loop doing:

Code:

char buffer[512];

void loop()
{
  if (emBlink > 500) {
    emBlink = 0;
    digitalToggleFast(13);
  }
  myusb.Task();
  CheckHostDevicesChanged();

  if (Serial.available()) {
    int ch = Serial.read(); // get the first char.
    Serial.print(ch);
    while (Serial.read() != -1) ;
  }
#if  defined(USB_TRIPLE_SERIAL) || defined(USB_DUAL_SERIAL)
  uint16_t avail;
  uint16_t avail_for_write;
  if ((avail = seremu.available())) {
    avail_for_write = SerialUSB1.availableForWrite();
    if (avail > avail_for_write) avail = avail_for_write;
    if (avail > sizeof(buffer)) avail = sizeof(buffer);
    seremu.readBytes(buffer, avail);
    SerialUSB1.write(buffer, avail);
  }

  if ((avail = SerialUSB1.available())) {
    avail_for_write = seremu.availableForWrite();
    if (avail > avail_for_write) avail = avail_for_write;
    if (avail > sizeof(buffer)) avail = sizeof(buffer);
    SerialUSB1.readBytes(buffer, avail);
    seremu.write(buffer, avail);
  }
#endif  

}

The code needs to test to make sure that seremu is connected... Will probably also update this code to handle the MTP with a Serial class as well, but it is nice right now that the Debug code running on the T4.1 plugged into another T4.1's USB port that the Serial stuff to and from that second Teensy is showing up on SerialUSB1 in another tab of TyCommander...

Note: the SEREMU class which is based off of RAWHID and the USBSerial code pointed out a bug in the current USBSerial code when you do a read operation it is getting the wrong byte... Will fix next.

Nice advance. There are devices used on bluetooth thread and there was the HDD/SSD/Flash Drive testing for file I/O, also the wired ethernet Dongle.

Having one base powered HOST Teensy with other devices 'Remote Teensy' sending in data to save to 'disk' or 'Bt' or other broadcast - or read from disk and send to other Teensy - etc.

Too many distractions

Most of my own making.

As mentioned I have build a version of SEREMU processing for USBHost. Also found bug in USBSerial USBHost code which I should retest.

Been playing with the MTP USBHost test code... Which some parts are a real hack, But:

I have a T41 running the mtp-test with a few different logical disks and Serial Emulation, plugged into the other T4.1 running the USBHost code.
Some things are real hack. In that I am building node list which the sketch works with. And Now have it enumerating the top level objects of the different storages plugged in. Updated Branch/Fork mentioned above.

Again I know it is off topic, but the data from the MTP shows:

Now maybe back to a previous distraction before I turn the storage units into File and FS objects and see if I can talk to
the actual files.

Edit: I should mention I am also able to see the files on my Kindle:

Indeed - too many distractions ... pulled the code from 2 hours ago down - need to add USB Host to that PCB I got now with digikey parts - or maybe another board would be less distracting ...

Maybe plug in an Android phone to see the messages ... sounds like a good distraction ...

That was Easy enough. Here is output from plugging in my phone to LogLow/TallDog board with T_4.0:

@KurtE - looking at the MENU on LG phone - I had to select MTP connect.

Doing it over startup - then select MTP on the phone gives the following:

We might need to enable some additional debugging.

I should also warn I put in hack for Kindle...
As it does not return the "Standard" of 6 1 1... But instead the tablet output a bogus value... Which as I mentioned in another post there is some other bogus mechanism Windows would determine if ti was an MTP device.
So I put quick VID:PID pair in the code to say if you see this assume MTP...

I look more in the morning.... Still resetting a few things after we had a power outage...

**defragster** · 12-22-2020, 02:18 AM

Will look for updates to see if it helps ... Our power flashed out some time ago ... Just enough to reset the kitchen device clocks.

With this device it is not setup by Class/Subclass/Protocol to be an MTP device

Like my Kindle Fire: So I have a hack table, in MTPDevice.cpp

Code:

const static known_mtp_devices_t known_mtp_devices[] PROGMEM = {
  {0x1949, 0x000C}

Where you might try adding another ROW: with same Vendor ID and your product ID = 0x231...
And see if it goes better.

Yes so far I don't know any way yet to say to MTP to say Hi There... So I hacked up @WMXZ version of MTP-Test to timeout after 5 or 10 seconds...

**defragster** · 12-22-2020, 03:15 AM

Ah - misread p#9 (hack for kindle) - thought it was setup special to detect Kindle as posted ...

**KurtE** · 12-23-2020, 03:55 PM

@all I have been playing some. Some of the MTP stuff is slightly broken, will fix. But I have a few commands in it that allow me to do things like try to enumerate a child, currently by storage ID... Also dump the list of IDs, and list of storages.

Need to fix where I think I am not linking things correctly when it enumerates again...

@Paul (and others) - I also did some more hacking on my new SEREMU USB Host handling. My current MTP test sketch looks for either Serial or SEREMU on the board plugged in and does echoing (both directions) of the Serial from the plugged in board to SerialUSB1 on the test sketch.

I just put in code that I hopefully will signal to the other side that I am here, such that code like: while (!Serial);
will know the port is now available...

Still needs more testing, but I have the HID Parser class remember the interface number. It already has a send Control Packet message function, needed for some devices like PS3 to send control messages.

Code looks like:

Code:

	//if (setup.word1 == 0x03000921 && setup.word2 == ((4<<16)|SEREMU_INTERFACE)) {
	tx_buffer_[0] = 0;
	tx_buffer_[1] = 0;
	tx_buffer_[2] = 0;
	tx_buffer_[3] = 0;
	driver_->sendControlPacket( 0x21, 0x9, 0x300, driver_->interfaceNumber(), 4, tx_buffer_)

Does this look reasonable?

Also should I do a Pull Request to add SEREMU plus fix the queue issue with the USBSerial class?
