Lenovo usb webcam problem

I have a Lenovo usb webcam.  I believe all was fine out of the box until I started also using Logitech usb headset.  Now not working with or without headset.  No idea why headset would matter, but that's the only relevant event I can think of.

dmesg | tail

yields

usb 1-1: new high speed USB device using ehci_hcd and address 4
usb 1-1: configuration #1 chosen from 1 choice
gspca: probing 17ef:4802
vc032x: check sensor header 20
vc032x: Sensor ID 143a (3)
vc032x: Find Sensor MI1310_SOC
gspca: probe ok
gspca: probing 17ef:4802

And

cat /dev/video0
cat: /dev/video0: Input/output error

And

Skype, for example, knows that I have a lenovo usb webcam in preferences but can't test the webcam.

This problem is robust to reinstalling the system.
