Can you please provide what you get when you read the "level" file
of the device's power directory?

Secondly, please verify, that it works before the STR cycle and post
a syslog of a suspend/resume cycle with CONFIG_USB_DEBUG and
only this device attached if possible. Thirdly, please verify that only
uvc is affected.

Please test it. It shouldn't work, but if it works there's a fundamental
flaw.
