RE: [PATCH] hid: usbhid: New hid quirks for Panasonic ElitePanaboard T-780 and T-880

[Anton Chikin]

Hello Jiri,

Thank you for your feedback.

With the generic hid driver device is working in mouse-mode, turning it into the huge touchscreen, which is completely useless for the end-user.

Moreover, the device has internal modes(mouse mode and touch mode) which we need to switch during work.

On some Linux systems hid driver is loaded from init.rd image, so we can't feed our quirks to it while boot process and we can't rebuild init.rd image on the user's machine because some Linux distributives doesn't have special tools preinstalled.

We are going to submit our driver to the Linux kernel quickly, so everyone can improve it.

Any comments and suggestions are greatly appreciated.

With best regards,
Anton Chikin

If the device is 'working' properly with the generic driver, "only" not 
properly calibrated, I wouldn't really like to blacklist it completely.

It might impose regression for those users who have written their own 
userspace calibration, for example.
