Confirmation of Support for "HID Version 1.00"?

[ruvsudrn]

Hi there, I am using TinyUSB with Arduino on a "Adafruit Feather RP2040 with USB Type A Host" board.

The USB host functionality is working well for most devices and I have also been able to enable the USB debugging via the TinyUSB library.

I have here an older trackball which identifies as "bcdUSB: 0x100 (USB Version 1.00)" and specifically "bcdHID : 0x0100 (HID Version 1.00)".

It works as expected on both Windows and Linux computers.

When connected to the "Adafruit Feather RP2040 with USB Type A Host" board the device is not detected as an HID device and no callbacks are made.

My question is whether I should expect a USB v1.0 and HID v1.0 device to work with TinyUSB? If not can anyone provide any hints as to how to modify the library to support this device? Perhaps I need to change some of the descriptor parsing for identification of HID devices?

If it helps, when I debug at level 3 I get the following output:

PS: Please tell me if you think this should be posted in the TinyUSB project discussion forum, rather than in the Arduino one. Thanks.

As a follow up to this, I now find that the older trackball works when a USB hub is placed between the trackball and the "Adafruit Feather RP2040 with USB Type A Host" board.

This really surprised me, and now I am digging through the debug info trying to work out why it would work with the hub but not without. My motivation is to not need the hub.
