USB is part of the low level transport and HID drivers should have no reasons to assume the USB driver is used and that it will stay forever. What I ask when we have such a case is to check on the report descriptor to see if there is anything we could use in it (usually the application) to skip this HID interface. Besides that, there is not much more to say. For having a look at the report descriptor, you can either use printk in the kernel, or use hid-recorder as root in https://gitlab.freedesktop.org/libevdev/hid-tools.

Yep, that works too. I knew there was an other way from the kernel but couldn't remember it :) I am more used to hid-recorder as it agregates everything in a more compact way and you can then replay the traces with hid-replay.

The ASUS T101HA keyboard dock generates HID events using the ASUS vendor specific UsagePage 0xff31. In consequence, some multimedia keys such as brightness up and down are not working with hid-generic. This commit adds the T101HA dock into the supported device list of the hid-asus driver. It also prevents the dock's integrated touchpad to be bound with hid-asus given that it is already working fine with hid-multitouch.
