[PATCH] USB: core: Add RESET_RESUME quirk for Keychron Ultra-Link 8K receiver

[PATCH] USB: core: Add RESET_RESUME quirk for Keychron Ultra-Link 8K receiver

[Daniel Quolke]

The Keychron Ultra-Link 8K wireless receiver (3434:d028, firmware 1.06)
disconnects from the bus on its own a few minutes after every system
resume. No error is logged before the disconnect; the mouse freezes
briefly while the receiver re-enumerates.

Resetting the device on resume instead of resuming it normally avoids
this. Booting with usbcore.quirks=3434:d028:b has kept it stable across
suspend/resume cycles.
