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.
