[fixed] Fix input/output error or find correct webcam driver for icecam2?
I have an icecam2 webcam (ID 0ac8:3420) (Sirius USB 2.0 camera). I run Ubuntu 9.10.
When I plug it in, /var/log/messages shows that uvcvideo has been loaded and has found a uvc 1.00 device.
When I run luvcview, I get the following error message:
Video driver: x11
A window manager is available
Device path: /dev/video0
Frame format: YUYV (MJPG is not supported by device)
Frame size: 352x288 (requested size 640x480 is not supported by device)
Frame rate: 5/1 fps (requested frame rate 30 fps is not supported by device)
Unable to start capture: Input/output error
Cleanup done. Exiting ...
I have two questions.
1) Apparently, the webcam is being detected. Some communication must be taking place since the computer knows the device's resolution. How do I fix the input/output error? I've tried setting the permissions for /dev/video0 to 777.
2) Most of what I've found via google suggests the gspca driver for this webcam. lsmod | grep gspca shows nothing, so I do not have it loaded. My question is: which gspca driver would I load?
ls of the appropriate kernel driver directory shows:
gspca_conex.ko gspca_pac207.ko gspca_spca506.ko gspca_tv8532.ko
gspca_etoms.ko gspca_pac7311.ko gspca_spca508.ko gspca_vc032x.ko
gspca_finepix.ko gspca_sn9c20x.ko gspca_spca561.ko gspca_zc3xx.ko
gspca_main.ko gspca_sonixb.ko gspca_sq905c.ko m5602
gspca_mars.ko gspca_sonixj.ko gspca_sq905.ko stv06xx
gspca_mr97310a.ko gspca_spca500.ko gspca_stk014.ko
gspca_ov519.ko gspca_spca501.ko gspca_sunplus.ko
gspca_ov534.ko gspca_spca505.ko gspca_t613.ko
As far as I can tell, there is no "main" driver. How do I determine which one applies to my webcam?
Thanks in advance
(BTW, I've already seen the ubuntu webcam page. It hasn't helped.)

Fixed! The problem was USB bandwidth. Can't use the camera through a USB hub.
