Subject: Re: [PATCH] hid: Add secondary vendor id for the marco, USB_DEVICE_ID_MS_TYPE_COVER_3_V2
Hello Jiri,
I believe the patch may work, but I would rename the IDs. Obviously
I can't test Surface 3 non-Pro cover, but the difference is likely due
to the following:
This is 0x07dc (I do own)
http://www.microsoftstore.com/store/msusa/en_US/pdp/Surface-Pro-Type-Cover/productID.300193600
This is 0x07de (I do not own)
http://www.microsoftstore.com/store/msusa/en_US/pdp/Surface-3-Type-Cover/productID.314885800
I would rename 0x07dc to USB_DEVICE_ID_MS_TYPE_COVER_PRO_3 (original
submitted patch)
and 0x07de to USB_DEVICE_ID_MS_TYPE_COVER_3 (Nicholas' patch).
I would probably also rename 0x07dd to USB_DEVICE_ID_MS_TYPE_COVER_PRO_3_JP.
At the time of my submission, there did not exist a Surface 3 non-Pro
to distinguish from my Surface 3 Pro, and it seems like the MS Type
Covers prior to Surface 3 series are compatible for both Pro and
non-Pro versions (Surface 2, Surface 2 Pro, Surface, and Surface Pro)
according to this:
http://www.microsoftstore.com/store/msusa/en_US/pdp/Type-Cover-2/productID.286867100
Thanks,
Alan
