I must be missing something stupid. Fortunately I have you guys to turn to, since USB hasn't been one of my strong points :) I have an Asus a7v-133-C mobo, which has USB enabled in the BIOS. I can't get this sucker to take a picture. All I get when I try to is something like this: **Output from "streamer -o test.jpeg" v4l: timeout (got SIGALRM), hardware/driver problems? ioctl: VIDIOCSYNC(int=0): Interrupted system call ioctl: VIDIOCMCAPTURE(frame=0;height=120;width=160;format=13): Invalid argument here is an excerpt from my bootlog, showing that the spca50x driver seems to be loading correctly: ----------------------------------SNIP----------------------------------- Jul 28 18:16:32 localhost kernel: USB Universal Host Controller Interface driver v2.2 Jul 28 18:16:32 localhost kernel: uhci_hcd 0000:00:04.2: UHCI Host Controller Jul 28 18:16:32 localhost kernel: uhci_hcd 0000:00:04.2: irq 12, io base 0000d400 Jul 28 18:16:32 localhost kernel: uhci_hcd 0000:00:04.2: new USB bus registered, assigned bus num ber 1 Jul 28 18:16:32 localhost kernel: hub 1-0:1.0: USB hub found Jul 28 18:16:32 localhost kernel: hub 1-0:1.0: 2 ports detected Jul 28 18:16:32 localhost kernel: uhci_hcd 0000:00:04.3: UHCI Host Controller Jul 28 18:16:32 localhost kernel: uhci_hcd 0000:00:04.3: irq 12, io base 0000d000 Jul 28 18:16:32 localhost kernel: uhci_hcd 0000:00:04.3: new USB bus registered, assigned bus num ber 2 Jul 28 18:16:32 localhost kernel: hub 2-0:1.0: USB hub found Jul 28 18:16:33 localhost kernel: hub 2-0:1.0: 2 ports detected Jul 28 18:16:33 localhost kernel: usb 1-2: new full speed USB device using address 2 Jul 28 18:16:33 localhost kernel: Linux video capture interface: v1.00 Jul 28 18:16:33 localhost kernel: /root/spca5xx-10072004/drivers/usb/spca50x.c: USB SPCA5XX camer a found.

I'm sure it must be common. Maybe a kernel upgrade? I have kernel 2.6.5-1.358 *sigh*
