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

Hello Jiri,

Actually our driver is implemented as the fork of usbhid driver. I'm now trying to move to HID bus. I think I need some help with this. 
I've copied /drivers/hid/hid-cando.c source code, changed device IDs in hid_driver structure, added my device IDs to /drivers/hid/hid-core.c hid_blacklist[] array, but my probe() method still never get called. Could you please help me with this?

My driver code and Makefile are in attachment.

Thank you.

Still, at least some very basic and limited/crippled functionality is there. So my preferred mode of operation now would be having the device being claimed by generic driver and wait for your proper full-fledged driver.

That would be great, I'll be happy to review and merge it. Are you planning to have it as a driver on HID bus, or completely separate USB driver?

Thanks,
