Comment 14 for bug 993655

As a workaround you could use something like this to add a quirk ignore the buttons:

sudo rmmod usbhid && sudo modprobe usbhid quirks=<lsusb id>:0x04

where lsusb id is the output of lsusb that corresponds to your device:
such as 0x041e:0x0403

Please update if this helps along with the lsusb ID of your device.

Thanks
