[sane-devel] Scanning in FreeBSD 5.3-RELEASE, niash, and a busy signal

Hello all,

My HP ScanJet 3300C will not scan due to being busy. I followed the 
steps of the FreeBSD manual and will show its output below in the event 
that it may help. I should note that the configuration is as follows:

Pentium III, 450 MHz

If I had to guess the problem, I would say that it is possible that the 
niash driver (that is the sane-backend for this scanner) does not work 
well with FreeBSD's kernel driver, the kernel driver and libusb do not 
coexist well, or scanimage is only trying to use libusb and the kernel 
driver is not allowing it to. I know when I installed sane-backends 
(make && make install && make clean with a fully-updated Ports tree), 
it installed libusb as well, and I know this scanner works with libusb 
(I have gotten it to work on Mac OS X this way), hence my above 
conclusion. Does anyone have any other input on this? I should also 
note that I am root running these commands and that I have rebooted 
since plugging it in just in case.
