RIOT/tests/sys/usbus_hid

Expected result

Connect you computer to the USB interface directly for the SoC and the USB interface for power and debug.

Flash the device.

After flashing the device executing the command:

dmesg

should contain logs stating that a new USB HID device was found.

The output should look like the following:

[18579.559436] usb 1-9: new full-speed USB device number 7 using xhci_hcd
[18579.701474] usb 1-9: New USB device found, idVendor=1915, idProduct=521f, bcdDevice= 0.00
[18579.701481] usb 1-9: New USB device strings: Mfr=3, Product=2, SerialNumber=0
[18579.701484] usb 1-9: Product: Usb Hid Test Device
[18579.701487] usb 1-9: Manufacturer: RIOT-os.org
[18579.704613] hid-generic 0003:1915:521F.0008: hiddev0,hidraw6: USB HID v1.10 Device [RIOT-os.org Usb Hid Test Device] on usb-0000:00:14.0-9/input0

Note, that the endpoint (in this case hidraw6) might differ.

After successful initialization of USB HID one should be able to communicate via USB HID simply by echoing input to the device.

Based on the screenshot above, an example command:

echo "Test" > /dev/hidraw6

The input string "Test" should be read by the test application and printed to stdout.
