There most likely will be a dynamically created device by the name of /proc/bus/usb/001/004 but it may not have the correct permissions. You need read and write permissions for the user that wants to use the scanner. Note that when you re-plug or power cycle the device it will change "names" (probably to /proc/bus/usb/001/005, 006 and so on). Unless you set up hotplug (or udev, which I still have to look into myself) to do this for you, you will need to do this manually every time you re-plug, power cycle the device or reboot. For USB scanners with a recent enough libusb (>= 0.1.6) and kernel (>= 2.4.12-ish. IIRC) there is no real need to muck with /dev/usb/scanner* anymore. For 2.6.x kernels /dev/usb/scanner* is not an option, really. > On Oct 24, 2005, at 6:40 PM, dark_m...@gmx.net wrote: > >> I'm using an Epson Stylus Photo RX 420 (scanner-printer-combo) on a >> Gentoo machine (Kernel 2.6.13). >> >> Sane is version 1.0.15 (back- and frontend). >> >> My problem is the following: >> >> sane-find-scanner detects my scanner correctly: >> >> found USB scanner (vendor=0x04b8 [EPSON], product=0x080f [USB MFP]) at >> libusb:001:004 >> >> But I don't find a device for the scanner anywhere.

What version? If you take care of the hotplug support it provides, most of the EPSON scanners should work out-of-the-box (unless your system has already switched to udev in favour of hotplug). >> [snip] Hope this helps, -- Olaf Meeuwissen FSF Associate Member #1962 sign up at http://member.fsf.org/ GnuPG key: 30EF893A/2774 815B DE83 06C8 D733 6B5B 033C C857 30EF 893A Penguin's lib! -- I hack, therefore I am -- LPIC-2
