Hello everyone,
I've recently bought an Acer Aspire Switch 11 convertible
tablet/notebook hybrid device. Ubuntu 14.04.2 with kernel 3.16 runs
almost perfectly, with one notable exception: on the keyboard dock, only
the touchpad works, not the keyboard itself. I've done a bit of digging
in the logs, and found the following error messages relating to HID:
[ 8.790574] hidraw: raw HID events driver (C) Jiri Kosina
[ 8.796341] hid (null): usage index exceeded
[ 8.845668] usbcore: registered new interface driver usbhid

The device in question has two endpoints:
T: Bus=02 Lev=02 Prnt=04 Port=02 Cnt=01 Dev#= 7 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

I: If#= 1 Alt= 0 #EPs= 2 Cls=03(HID ) Sub=01 Prot=02 Driver=usbhid
According to lsusb, the second one is a mouse (= touchpad), while the
first one is a keyboard (see attached lsusb.txt). Judging from the
dmesg, this is also the one which fails to initialize. Can anyone
suggest any quirks/fixes to try here?
Thanks & best regards, Florian

Hi Florian,
This was a known bug which has been fixed in a more recent kernel than
3.16. I think a 3.17 might work, but I think a 3.18 would be a better
choice.

thanks for the quick reply. I've tried both 3.18.7 and 3.19.0 kernels,
but still get (slightly different) error messages:
[ 2.550306] hidraw: raw HID events driver (C) Jiri Kosina
[ 2.877672] hid (null): usage index exceeded
[ 2.927474] usbcore: registered new interface driver usbhid

[ 3.153921] hid-generic: probe of 0003:06CB:2991.0003 failed with
error -22
After a bit of digging through the kernel code, could it be that the
06CB:2991 device needs to be added to the hid_have_special_driver list
(which AFAICT will only appear in 4.0)?
Best regards, Florian

Ouch. Now that I can see that, I remember that there was a half-backed
solution here:
https://patchwork.kernel.org/patch/5737231/

If you just add the VID/PID to hid_have_special_driver, and nowhere
else, your device will not work at all, nor the touchpad which shares
the same VID/PID (see Andrew's answer).
So this won't do :(

Benjamin
