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.
