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 PowerC@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 POWERC@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 [31636.760176] gspca: video0 created [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 mmap method VIDIOC_STREAMON error 5, Input/output error Here is the USB descriptor of the device: Trust 610 LCD POWERC@M ZOOM Manufacturer: Trust Speed: 12Mb/s (full) USB Version: 1.00 Device Class: 00(>ifc ) Device Subclass: 00 Device Protocol: 00 Maximum Default Endpoint Size: 8 Number of Configurations: 1 Vendor Id: 06d6 Product Id: 0031 Revision Number: 1.00 Config Number: 1 Number of Interfaces: 2 Attributes: 80 MaxPower Needed: 500mA Interface Number: 0 Name: sunplus Alternate Number: 0 Class: ff(vend.)
