I can't get into a useful dialogue with a HP4200C ScanJet USB-scanner on my system.
After booting, things seem all right (see the relevant following messages after booting) though of the scanner only vendor and product number are given. No model name, but this may be normal behaviour. usb.c: registered new driver usbdevfs usb.c: registered new driver hub usb.c: registered new driver usbscanner scanner.c: USB Scanner support registered. ip_conntrack (2048 buckets, 16384 max) IPv6 v0.8 for NET4.0 IPv6 over IPv4 tunneling driver usb.c: registered new driver hid mice: PS/2 mouse device common for all mice usb-uhci.c: $Revision: 1.259 $ time 14:29:49 May 18 2001 usb-uhci.c: High bandwidth mode enabled PCI: Found IRQ 11 for device 00:07.2 PCI: The same IRQ used for device 00:0b.0 usb-uhci.c: USB UHCI at I/O 0xd000, IRQ 11 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected hub.c: USB new device connect on bus1/2, assigned device number 2 scanner.c: probe_scanner: User specified USB scanner -- Vendor:Product - 3f0:105 scanner.c: USB Scanner support registered. After giving the command: scanimage hp4200:/dev/usbscanner the system does not return. Neither does it scan. Looking at the messages after this command I find the following result: Linux video capture interface: v1.00 i2c-core.o: i2c core module i2c-algo-bit.o: i2c bit algorithm module bttv: driver version 0.7.57 loaded bttv: using 2 buffers with 2080k (4160k total) for capture bttv: Host bridge needs ETBF enabled.

I have SuSE Linux 7.2 >From http://hp4200-backend.sourceforge.net/ I downloaded and installed sane-backend-1.0.5.tar.gz sane-frontends-1.05.tar.gz sane-backend-1.0.5-hp4200-0.2-p1.patch.gz Before this I had already installed the linux kernel sources and in file scanner.h the line #define SCN_IOCTL was uncommented. This all according what is advised in http://hp4200-backend.sourceforge.net/ Giving the command: cat /proc/bus/usb/devices gives: T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 11/900 us ( 1%), #Int= 1, #Iso= 0 D: Ver= 1.00 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 0.00 S: Product=USB UHCI Root Hub S: SerialNumber=d000 C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)
