This looks like some kind of UHCI problem. I have the same camera
(well, it is a Creative Webcam plus, but same chipset) with an Intel
UHCI controller and I haven't seen any errors. Here is my USB
controller:

00:07.2 USB Controller: Intel Corporation 82440MX USB Universal Host
Controller (prog-if 00 [UHCI])
Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B-
Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium
>TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 64
Interrupt: pin D routed to IRQ 11
Region 4: I/O ports at fcc0 [size=32]
