Hi, I'm in a tricky situation -- at work I have a Opteron workstation running the antiquated RHEL3 os with no opportunity by me to upgrade anything except by installing newer versions of software in my user prefix (I can gain root access to tweak hotplug scripts, etc, but shouldn't upgrade system packages). I've installed libusb-0.1.12, sane-backends-1.0.19 and sane-frontends-1.0.14 in my user prefix.
I'm trying to get a Canon LiDe25 scanner working here (it works fine at home with my newer machines). This is the tail of the error I get from scanimage -L: [sanei_usb] sanei_usb_open: opened usb device `libusb:001:017' (*dn=0) [sanei_usb] sanei_usb_get_vendor_product: device 0: vendorID: 0x04a9, productID: 0x2220 [sanei_usb] sanei_usb_write_bulk: trying to write 4 bytes [sanei_usb] 0000: 01 69 00 01 .i.............. USB error: error submitting URB: Invalid argument [sanei_usb] sanei_usb_write_bulk: write failed: Invalid argument [sanei_usb] sanei_usb_close: closing device 0 And here's an ominous /var/log/messages entry: Feb 20 10:22:26 myhost kernel: ioctl32(scanimage:17106): Unknown cmd fd(3) cmd( 802c550a){00} arg(ffff50f0) on /proc/bus/usb/001/017 I've had hotplug USB errors on this box before when too many things were plugged in (order of hotplug is important). So I'm using a powered USB hub to power the scanner but the results haven't changed. The scanner is on 1/17: $ lsusb Bus 001 Device 017: ID 04a9:2220 Canon, Inc. Any pointers on what these messages mean? -------------- next part -------------- An HTML attachment was scrubbed...
