Appears that ObtainThread is working alright in so far that it scheduled all eight UsbStartIsoTransfer()s. Still error code [0000280] which means timeout error.

Perhaps the 3 seconds timeout value is just too short. Therefore I now changed it to wait forever. Please test and report again.

Regards
Wim

Thanks Wim

The camera keeps the lights up, but I get no image on vmvideo.exe (no parameters).
I'm attaching the log.

Thanks Martin,

After scheduling all eight UsbStartIsoTransfer(s) the ObtainThread now awaits forever signalling of their completion by the USB Host Controller Driver.
Apparently this signalling does not occur at all. Reason unknown. It seems to me that there is something wrong with the 12.14 USB Host Controller Driver.
Perhaps it is a good idea to plugin an external webcam to see whether or not  that webcam does indeed work well with the USB Host Controller Driver.

Regards,
Wim
