I am attempting to use an Epson PX-A550 (US model CX4600) using the
epkowa backend (1.0.195 in sane-backends 1.0.15) from an IBM ThinkPad
X40 laptop using kernel 2.6.11 and libusb 0.1.10a both from Debian
GNU/Linux. sane-find-scanner finds the scanner but when I try to use
it e.g. with scanimage -L, it fails. Attached is a debug log captured
with `SANE_DEBUG_SANEI_USB=3D128 SANE_DEBUG_DLL=3D128
SANE_DEBUG_EPKOWA=3D128 scanimage -L` and my /proc/bus/usb/devices file
at that time. My dll.conf file only contains the single entry for
epkowa as this scanner is supported only by that driver. The error
point is the first time epkowa attempts to send the initialize command
to the device; the command apparently never reaches the scanner
because libusb returns a "No such file or directory" error immediately
when trying to talk to the found endpoint. I can't tell if something
is failing earlier in the initialization.
Any advice greatly appreciated,

A man without doubt is a monster.
