Hi,

 Problems with Creative Webcam III. This worked fine
in test13-pre4, haven't tried pre5 & 6.

On boot:

 usb_control/bulk_msg: timeout
 usb_control/bulk_msg: timeout
 usb.c: couldn't get all of config descriptors
 usb.c: unable to get device 2 configuration (error=-110)
 hub.c: USB new device connect on bus1/1, assigned device number 4
 usb_control/bulk_msg: timeout
 usb.c: USB device not accepting new address=4 (error=-110)

On remove/reinsert:

 hub.c: USB new device connect on bus1/1, assigned device number 5
 usb_control/bulk_msg: timeout
 usb.c: USB device not accepting new address=5 (error=-110)
 hub.c: USB new device connect on bus1/1, assigned device number 6
 usb_control/bulk_msg: timeout
 usb.c: USB device not accepting new address=6 (error=-110)

USB controller is:

00:04.2 USB Controller: VIA Technologies, Inc. UHCI USB (rev 10) (prog-if
00 [UHCI])
        Subsystem: Unknown device 0925:1234
        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: 32, cache line size 08
        Interrupt: pin D routed to IRQ 5
        Region 4: I/O ports at d400 [size=32]
        Capabilities: [80] Power Management version 2
                Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA
PME(D0-,D1-,D2-,D3hot-,D3cold-)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-


The only other thing of relevance in dmesg, is the flood of
irq warnings related to the two USB controllers on 4.2 & 4.3 :-

 PCI: Found IRQ 5 for device 00:09.0
 PCI: The same IRQ used for device 00:04.2
 PCI: The same IRQ used for device 00:04.3
 PCI: Found IRQ 5 for device 00:04.2
 PCI: The same IRQ used for device 00:04.3

 PCI: Found IRQ 5 for device 00:04.3
 PCI: The same IRQ used for device 00:04.2
