The generic USB driver is the driver for your USB chipset. There are basi= cally=20 two kinds: UHCI (Intel, Via) and OHCI (some other vendors, can't remember= ).=20 To make matters more complicated, the UHCI drivers comes in two flavours:= =20 Either as module "uhci" or as module "usb-uhci". It seems that the latter= =20 works a lot faster.=20 You have to modprobe one of these modules before loading the scanner modu= le,=20 but since you get an output from "cat /proc/bus/usb/devices" you already=20 loaded the correct module (ohci in your case). > I configured USB scanner support into the kernel, it works as a module. > I am using the CVS version of SANE and the 20020926 snapscan backend > (which version is in CVS SANE?). The version in CVS SANE is a bit newer but doesn't have any advantages fo= r=20 your scanner. > Hopefully someone can interpret this for me. > The first cat is after I booted. > The scanner is recognized but there is no driver has claimed that > interface (the usbscanner as mentioned in the docs at > http://snapscan.sourceforge.net/). > usbscanner is supposed to be mentioned.

Your webcam isn't handled by the scanner module. In a later kernel versio= n you=20 hopefully won't have to supply the IDs. Until the IDs of newer scanners a= re=20 added to the kernel, you have to supply them manually. Regards, Oliver
