Hi John, looks like your patch 09c96980dc72 breaks usb on rk3188 / radxa-rock. I don?t get any error message and even the usb hub is detected but no attached usb device works. After reverting 09c96980dc72 (and the related patches) everything is fine again. I tested next-20160212 and v4.5-rc3. Do you have any idea how to fix that?
