webcam id 174f:6a31, kernel 2.6.36-desktop-2mnb, amd64.
in various programs (skype, ekiga) I get a *lot* of "Error: Register 0x0001 = 2", from function stk11xx-dev.c::dev_stk11xx_watchdog_camera.
I disabled it for myself (added a 'return 0') and had no problem w/ it in skype and ekiga.
That register might not actually have any watchdog behind it.
I recommend not doing that read (do like me some 'return 0'), or, at the minimum, do not display any message - or use STK_DEBUG instead of
STK_ERROR.
