Hi Laurent, many thanks for replying to my messsage and thanks,too for the effort you are spending providing these drivers!
Following your advice, I checked for both installations: @opensuse 11.1: <6>usb 4-1: new full speed USB device using ohci_hcd and address 2 <6>usb 4-1: configuration #1 chosen from 1 choice <6>usb 4-1: New USB device found, idVendor=0471, idProduct=0333 <6>usb 4-1: New USB device strings: Mfr=0, Product=1, SerialNumber=0 <6>usb 4-1: Product: USB Video Camera lsmod | grep -i hci_hcd: ohci_hcd 36548 0 ehci_hcd 55348 0 usbcore 198656 8 snd_usb_audio,usbhid,snd_usb_lib,uvcvideo,usb_storage,ohci_hcd,ehci_hcd @opensuse 11.0: =============== <6>usb 2-3: new high speed USB device using ehci_hcd and address 2 <6>usb 2-3: configuration #1 chosen from 1 choice <6>usb 2-3: New USB device found, idVendor=0471, idProduct=0333 <6>usb 2-3: New USB device strings: Mfr=0, Product=1, SerialNumber=0 <6>usb 2-3: Product: USB Video Camera lsmod | grep -i hci_hcd: ehci_hcd 56204 0 ohci_hcd 42628 0 usbcore 188376 8 snd_usb_audio,usbhid,snd_usb_lib,uvcvideo,usb_storage,ehci_hcd,ohci_hcd It looks like, that in 11.1 ohci_hcd is loaded first and ehci_hcd second. Then the device gets initialized with the ohci_hcd and the uvc driver believes it's got a slow usb camera. Does that make sense? If yes, where to change the order?
