<sigh> yes - the same thing happens when running
sane-find-scanner as root. Good attempt though - that
is the most common reason something cannot be got. Normally, though, it is reported as access denied or "locked" when I check. Then I go "DOH!" and sudo...
I should have mentioned: I have read the man pages. There is a neat howto in there - which dosn't deal with the situation that libusb is not available.
I have also read through the faq and the mini-howto in
www.sane-project.org
I have successfully helped other people with permissions and so on and so forth ... including getting the correct driver. However, I have not found any situation where libusb is "not available" when it is in fact installed.
I figured I may just have the wrong version - and upgraded everything with usb in it I could find. Also looked to see if there were usb packages to install. But it appears I have everything. (However I don't know what sane is expecting here.)
Perhaps libusb is in a different place - anyone with ubuntu experiencing this problem? Or perhaps there is an app which is hogging libusb so nothing else can use it?
Note: this works fine in Fedora Core 4.
Interestingly, it did work the first time I tried it - no idea what is different this time ... only thing that happened betweentimes is that my battery went flat unexpectedly. So perhaps there is a cache somewhere remembering that san-find-scanner is using libusb from the previous attempt. (In the previous attempt - sane-find-scanner detected the scanner correctly but scanimage -L didn't. Once I've got this figured out I can figure out that
)
