As requested I forward my bug report to the list: >From time to time on an ASRock IMB-181D motherboard this device fails to be added. It seems to work reliably when using Windows 7. The errors in dmesg vary but usually take the form: [ 5.328040] usb 3-7: string descriptor 0 read error: -71 (snip) [ 10.333605] usbhid 3-7:1.0: can't add hid device: -71 [ 10.333639] usbhid: probe of 3-7:1.0 failed with error -71 I can provide a PicoLCD unit if necessary and possibly also fund a fix/workaround.
