[sane-devel] sane-find-scanner finds Lide20, plustek backend does not
Thu, 23 Sep 2004 09:42:55 -0700
My Canon Lide20 (USB) was working on Mandrake 9.0 (sane 1.0.11, iirc and
Linux 2.4.x) using scanner.o. I upgraded to Mandrake 10.0 (sane 1.0.13,
Linux 2.6.3) and I found scanner.o has been discontinued, and I have to
use libusb. Sane tells me the scanner is supported with plustek backend.
Now, the scanner shows up on usbview and in sane-find-scanner:
found USB scanner (vendor=0x04a9 [Canon], product=0x220d [CanoScan],
chip=LM9832/3) at libusb:001:002
It's also in /proc/bus/usb/devices as:
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=ff(vend.) Sub=00 Prot=ff MxPS= 8 #Cfgs= 1
P: Vendor=04a9 ProdID=220d Rev= 1.00
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=ff Driver=(none)
E: Ad=81(I) Atr=03(Int.) MxPS= 1 Ivl=16ms
E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=03(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
(I'm a bit concerned about the "Driver=(none)" - can I change that?)
I took the vender and product IDs from sane-find-scanner and made
[usb] 0x04a9 0x220d
/etc/fstab has the line:
none /proc/bus/usb usbfs defaults,devmode=0666 0 0
(BTW: I'm the only user, so I don't care that ALL users have permission...)
however, when I set the debug on and run scanimage -L, I get:
[plustek] No matching device found!
[plustek] open failed: -1
I've also tried making a /dev/usbscanner with mknod and using that, but
that doesn't work either.
Any help would be greatly appreciated!
