I had missed it before, but your device sets the bInterfaceProtocol value to 1 as it's UVC 1.5 compliant, as opposed to value 0 for UVC 1.1. The uvcvideo driver doesn't support UVC 1.5 yet. It looks like your camera supports the UVC 1.1 protocol as well, but that's not true of all UVC devices in general. I expect that enabling detection of UVC 1.5 support in the driver will result in issues with UVC 1.5 devices, but on the other hand those devices are currently not supported at all. I'll thus submit a patch to enable UVC 1.5 device detection, and we'll see how that goes. I'll CC you and would appreciate if you could test the patch. -- Regards, Laurent Pinchart ^ permalink raw reply [flat|nested] 8+ messages in thread
