Hi,
I tried the gspca_sunplus driver from http://linuxtv.org/hg/~jfrancois/gspca/
rev 13915 on top of Linux kernel 2.6.32. When I plug the Trust 610 LCD pow...@m
Zoom
device in webcam mode (0x06d6:0x0031) then two devices are created: /dev/video0
and /dev/video1:
[31636.528184] usb 3-2: new full speed USB device using uhci_hcd and address 5
[31636.740722] usb 3-2: New USB device found, idVendor=06d6, idProduct=0031
[31636.740744] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[31636.740760] usb 3-2: Product: Trust 610 LCD pow...@m ZOOM
[31636.740772] usb 3-2: Manufacturer: Trust
[31636.744229] usb 3-2: configuration #1 chosen from 1 choice
[31636.747584] gspca: probing 06d6:0031

[31636.760643] gspca: probing 06d6:0031
[31636.772063] gspca: video1 created
The /dev/video0 is working correctly but the /dev/video1 just causes error:
$ ./svv -d /dev/video1
raw pixfmt: JPEG 464x480
pixfmt: RGB3 464x480

VIDIOC_STREAMON error 5, Input/output error
