canoscan n670u device read error
i, im having some problems with using my canon canoscan
n670u on slack 9.1 kernel 2.4.22. im using xsane and the error i get is: Error during read: Error during device I/O importantly, xsane *finds* the device but i get that error when previewing/scanning. the same error i get with scanimage. also importantly, this scanner did work a few days ago! i did the same thing with xsane and it was fine! to me it seems as if everything is ok and yet i get I/O errors (tried as root btw) scanimage -L finds the scanner sane-find-scanner finds it and the scanner starts making noises for about a second, then waiting for a few seconds, and then i get an error. please help. thanks. shellcode@ph33r:~$ dmesg ............................................. usb.c: registered new driver usbdevfs usb.c: registered new driver hub uhci.c: USB Universal Host Controller Interface driver v1.1 PCI: Found IRQ 11 for device 00:1f.2 PCI: Sharing IRQ 11 with 02:0b.0 PCI: Setting latency timer of device 00:1f.2 to 64 uhci.c: USB UHCI at I/O 0xef80, IRQ 11 usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected i810_rng hardware driver 0.9.8 loaded hub.c: new USB device 00:1f.2-2, assigned address 2 usb.c: USB device 2 (vend/prod 0x4a9/0x220d) is not claimed by any active driver. usb.c: registered new driver usbscanner scanner.c: USB scanner device (0x04a9/0x220d) now attached to scanner0 scanner.c: 0.4.13:USB Scanner Driver ident: nic h/w: id=0x800c 1.0.0 ident: pri f/w: id=0x15 1.0.7 ident: sta f/w: id=0x1f 1.3.6 .............................................. shellcode@ph33r:~$ /sbin/lsmod Module Size Used by Not tainted snd-pcm-oss 37252 0 snd-mixer-oss 11992 0 [snd-pcm-oss] scanner 10488 0 i810_rng 2656 0 (unused) uhci 24496 0 (unused) usbcore 58400 1 [scanner uhci] prism2_plx 61020 2 p80211 18456 0 [prism2_plx] snd-ens1371 11596 0 gameport 1452 0 [snd-ens1371] snd-pcm 55904 0 [snd-pcm-oss snd-ens1371] snd-timer 13252 0 [snd-pcm] snd-page-alloc 6004 0 [snd-pcm] snd-rawmidi 12512 0 [snd-ens1371] snd-seq-device 3920 0 [snd-rawmidi] snd-ac97-codec 37240 0 [snd-ens1371] snd 27460 0 [snd-pcm-oss snd-mixer-oss snd-ens1371 snd-pcm snd-timer snd-rawmidi snd-seq-device snd-ac97-codec] soundcore 3332 6 [snd] pcmcia_core 40032 0 ide-scsi 9424 0 agpgart 39576 0 (unused) shellcode@ph33r:~$ cat /proc/bus/usb/devices 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-alt Root Hub S: SerialNumber=ef80 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.)
