This is a followup to my message about the Creative VF0410 Live! Cam Video IM Pro (041e:4063)
I changed the uvc_trace_param in uvc_driver.c, so that I could get more information about what is going on: unsigned int uvc_trace_param = UVC_TRACE_PROBE | UVC_TRACE_DESCR | UVC_TRACE_CONTROL | UVC_TRACE_FORMAT | UVC_TRACE_CAPTURE | UVC_TRACE_CALLS | UVC_TRACE_IOCTL | UVC_TRACE_FRAME; Now when I insmod the driver, and plug in the webcam I get: [ 2626.794551] usb 5-8: new high speed USB device using ehci_hcd and address 12 [ 2626.968643] usb 5-8: configuration #1 chosen from 1 choice [ 2626.969218] uvcvideo: Probing generic UVC device 8 [ 2626.969234] uvcvideo: Found format YUV 4:2:2 (YUYV).
