There are numerous hardware variants sold by several vendors, mostly using generic names like "GK61" for the 61-key version. These keyboards are sometimes known collectively as the "GK6X" series. The keyboard has three USB interfaces. Interface 0 uses the standard HID boot protocol, limited to eight modifier keys and six normal keys; interface 2 uses a custom report format that permits any number of keys. If more than six keys are pressed simultaneously, the first six are reported via interface 0 while subsequent keys are reported via interface 2. (Interface 1 uses a custom protocol for reprogramming the keyboard; this can be controlled through userspace tools and is not of concern for the present driver.) The report descriptor for interface 2, however, is incorrect (for report ID 0x04, the input field is marked as "array" rather than "variable".) The descriptor appears to be correct in other respects, so we simply replace the incorrect byte before parsing the descriptor.

This sometimes leads to several "failed to fetch feature 8" messages getting logged, after which the touchpad may or may not work. Just like the K15A these errors are triggered by undocking and docking the tablet. There also seem to be other problems when undocking and then docking again in quick succession. It seems that in this case the keyboard-controller still retains some power from capacitors and does not go through a power-on-reset leaving it in a confuses state, symptoms of this are: 1. The USB-ids changing to 048d:8910 2. Failure to read the HID descriptors on the second (mouse) USB intf. 3. The touchpad freezing after a while These problems can all be cleared by undocking the keyboard and waiting a full minute before redocking it. Unfortunately there is nothing we can do about this in the kernel.
