Red Hat Bugzilla – Bug 135802
missing entries in libsane.usermap from sane-backends
Last modified: 2007-11-30 17:10:51 EST
Description of problem: Recently I got my paws on a USB scanner. It is actually recognized and supported by SANE 1.0.14 (and scans quite nicely). 'scanimage -L' reports: device `epson:libusb:001:002' is a Epson GT-X700 flatbed scanner This is correct. GT-X700 is a marketting name used in Asia for the same machine known in North America and Europe as "Perfection 4870 Photo", The problem is that in /etc/hotplug/usb/libsane.usermap an entry for that device does not exist and on hotplug events /etc/hotplug/usb/libusbscanner script does not run. Adding an entry similar to other already existing but with "0x04b8 0x0128" for USB identfiers immediately wakes up that script. No idea how many other such entries may be missing. Version-Release number of selected component (if applicable): sane-backends-1.0.14-6
Could you please paste in the exact line that works for you? Thanks.
This is exactly what I added in libsane.usermap: # Epson Corp.|Perfection 4870 Photo libusbscanner 0x0003 0x04b8 0x0128 0x0000 \ 0x0000 0x00 0x00 0x00 0x00\ 0x00 0x00 0x00000000 with this exception that the second one is really a one long line instead of beeing broken/joined with '\'s. The same as with other Epson scanners in this file; only a number in the fourth field is different (the highest one is currently 0x011f). The difference is that in FC2 I had to add in a config file in /etc/sane.d a line which said usb 0x4b8 0x128 before 'sane-find-scanner' started to react, so this was an "unknown scanner" and an absence of a line above from libsane.usermap was not surprising, while a version of sane used currently knows about that hardware and a more "choosy" 'scanimage -L' reports it immediately, but the line above is still missing in libsane.usermap.
Reported upstream.
sane-backends-1.0.15-9, as supplied with FC4, are still lacking that simple entry. It shows up as # Epson Corp.|Perfection 4870 Photo (GT-X700) in sane-backends-1.0.16-1, and some other similar entries too, which one can find for the current "rawhide". Well over a year before that one-liner will be in distributions seems like an awfully long time. "Perfection 4870" is likely already replaced by something else in stores.
