Re: [PATCH] HID: use generic driver for ThingM blink(1) if !CONFIG_HID_THINGM

[Reilly Grant]

If the software is using usbdevice_fs, no, it can simply detach the
kernel driver. If the software is using hidraw then this blacklist
becomes the issue because even if you unload the special driver the
generic HID driver won't load. Is there a mechanism in the HID
subsystem for drivers to build on top of the generic one instead of
replacing it?
