[sane-devel] Epson Perfection 2400 Photo scanner problems

[brook@biology.nmsu.edu]

I am trying to get an Epson Perfection 2400 Photo scanner working with
sane v1.0.12 on a NetBSD box.  sane-find-scanner reports it correctly
as:

     found USB scanner (vendor=0x04b8, product=0x011b) at libusb:/dev/usb1:/dev/ugen0

However, running scanimage -L (with SANE_DEBUG_EPSON=255) yields the
following:

     [sanei_debug] Setting debug level of epson to 255.

     [epson] send buf, size = 2
     [epson] buf[0] 1b .
     [epson] buf[1] 49 I

At that point it hangs indefinitely.

Any pointers on how to debug this are welcome.  Thanks for your help.

Cheers,
