USBHost Stops after Identifying USB device PID/VID before Finding Tablet PID/VID

**mjs513** · 08-11-2022, 04:56 PM

While playing with the new WACOM Library (https://forum.pjrc.com/threads/70824...-Intuos5/page2) I plugged in a HUION Inspiroy H640P Graphics Drawing Tablet and ran @KurtE's new HIDDeviceInfo sketch. However, I was expecting to see the PID/VID for the tablet:

Code:

endor  ID:        256C
Product ID:        006D

but instead received a PID/VID for a USB device:

Code:

Device Descriptor:
  12 01 10 01 00 00 00 40 16 04 00 3F 00 00 01 02 00 01 
    VendorID = 0416, ProductID = 3F00, Version = 0000
    Class/Subclass/Protocol = 0 / 0 / 0
    Number of Configurations = 1
enumeration:
enumeration:
Manufacturer: Nuvoton
enumeration:
Product: WPM USB

If I run USBHost Shield 2.0 HIDDesc, USB_desc with the following config (some of the time = on first upload of sketch):

Code:

USB     Usb;
USBHub  Hub1(&Usb);

it does enumerate correctly:

Code:

I decided to attach a Teensy 3.6 and rerun the DeviceInfo sketch. This time it looks like it picked up both devices but with errors on the tablet:

Code:

**KurtE** · 08-15-2022, 07:22 PM

@mjs513 - Did you ever get any clues on why the USB Descriptor including PID/VID is different on the T4.x boards
versus T3.6 as well as Windows, Ubuntu including RPI?

As far as I know we are just reporting what the Device descriptor is saying:

Code:

Device Descriptor:
  12 01 10 01 00 00 00 40 16 04 00 3F 00 00 01 02 00 01 
    VendorID = 0416, ProductID = 3F00, Version = 0000
    Class/Subclass/Protocol = 0 / 0 / 0
    Number of Configurations = 1
enumeration:

With the T3.6 dump did it actually report as two different devices?

Code:

Device Descriptor:
  12 01 10 01 00 00 00 40 16 04 00 3F 00 00 01 02 00 01 
    VendorID = 0416, ProductID = 3F00, Version = 0000
    Class/Subclass/Protocol = 0 / 0 / 0
    Number of Configurations = 1
enumeration:
enumeration:

and:

Code:

enumeration:
Device Descriptor:
  12 01 10 01 00 00 00 08 6C 25 6D 00 00 00 05 06 00 01 
    VendorID = 256C, ProductID = 006D, Version = 0000
    Class/Subclass/Protocol = 0 / 0 / 0
    Number of Configurations = 1
enumeration:
ERROR Followup
    remove from followup list
    remove from followup list
    stray halted 1FFFAAC0
  qtd: 1FFFAAC0, token=80008080, next=1FFFAB40

Maybe something we are not handling? Like Composit Device?

I think that is beyond my pay grade...

Paul?

and it shows that it picks up the WPM USB device and does finish setting up the Device itself.

On the T3.6 and in Windows and Linux it first picks up the WPM USB and then disconnects it but then continues to pick up the Device itself:

showing it claiming 2 devices. But that is leading to another issue that probably should post on the other thread

@mjs513 - Any luck yet on this one running on T4.x?

At this point not sure what else to try with this one. I did purchase the other version of their tablet and it is not showing the same issue.

One interesting thing is, that mine actually shows the same VID/PID on the Teensy as yours does on everything BUT the T4.x.

Would be interesting to see what the USB actually is doing with this device on the different platforms.
The best way would be to use something like the Beagle 480 (or 12 would work in this case), but I don't have one.

The WireShark info, might also work, I should probably spend some more time trying to understand their output.

I am too used to now using the Saleae Logic output (with my own edited analyzers). They aren't perfect but at least it is working pretty well to cut down
the 100s of thousands of lines of output (maybe more) down to a few hundred.
But the hard part is setting up a way to capture.

For PC to devices, I have a hacked-up hub that is easy to clip the clips to. Before this, I would use, a small USB extension cable, where I stripped off some of the wire insulation to the point, I could again use the clips
to the LA... Yes PIA!

But for now, maybe we should just leave this one, as another unexplained oddity.

@KurtE

No luck in getting the T4.x to recognize the tablet. Did try forcing 12Mbit/sec but still hung after finding the WPM USB device.... Again I did try using USBHost Shield 2 just to see if would recognize the tablet and it does but did have some problems but eventually did recognize it.

So far anything else I have hooked up the tablet to has worked.

So agreed - right now its just another issue with USBHost.
