Subject: Re: [PATCH] hid: Add secondary vendor id for the marco, USB_DEVICE_ID_MS_TYPE_COVER_3_V2

Hi Jiri,
  I think I have given my input on what should be done with the code.
I'll leave it up to you to decide whether to accept the patch or not.
Please do let me know if you have any questions you want to ask me.

  I would recommend that Nicholas change the 0x07dd to PRO though, as
they might also have a regular Surface 3 in Japan that is different
than yours.

Thanks,
Alan
