Hi all, I recently bought a "Hercules Dualpix Chat and Show" webcam, after seeing it in the HCL of uvcvideo module. I hoped for it to work without any tweaking, but no luck. So I tried googling and trying to apply the suggested fixes but it didn't help. On Debian I installed the module with: module-assistant a-i linux-uvc revision 238, but I also tried with rv 239 from svn.
At first, it complained giving this output in dmesg: Linux video capture interface: v2.00 usbcore: registered new interface driver uvcvideo USB Video Class driver (v0.1.0) usb 4-5: new high speed USB device using ehci_hcd and address 5 usb 4-5: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device Hercules Dualpix Chat and Show Webcam (06f8:3007) uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -32 (exp. 26). uvcvideo: Failed to query (129) UVC control 1 (unit 0) : -32 (exp. 26). uvcvideo: Failed to initialize the device (-5). 5:3:1: cannot get freq at ep 0x84 usb 4-5: New USB device found, idVendor=06f8, idProduct=3007 usb 4-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 4-5: Product: Hercules Dualpix Chat and Show Webcam usb 4-5: Manufacturer: Guillemot Corporation Then I put in /etc/modprobe.d/uvcvideo: install uvcvideo /sbin/modprobe snd_usb_audio; /sbin/modprobe --ignore-install uvcvideo to postpone uvcvideo's loading to the usb audio's one, and also tried do to the same thing by hand, using insmod. The result is that the error msg about query 129 disappeared, the one about query 135 is still there, the module creates the /dev/video0 device, but the webcam doesn't work. Strangely, the webcam is not listed in lsusb's output. Any suggestion? Thanks, Carmelo PS Current dmesg output when I unplug and plug the camera: usb 4-5: USB disconnect, address 6 usb 4-5: new high speed USB device using ehci_hcd and address 8 usb 4-5: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device Hercules Dualpix Chat and Show Webcam (06f8:3007) uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -32 (exp. 26). input: Hercules Dualpix Chat and Show W as /class/input/input12 8:3:1: cannot get freq at ep 0x84 usb 4-5: New USB device found, idVendor=06f8, idProduct=3007 usb 4-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 4-5: Product: Hercules Dualpix Chat and Show Webcam usb 4-5: Manufacturer: Guillemot Corporation _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
