Cups Issues?

[ShadowfoxXXX]

I have a canon pixma mg2120 that i cant seem to access.
It is supposedly supported by gutenprint
I'm not sure if the issue lies with CUPS or the drivers or something else.

lsusb shows
$this->bbcode_second_pass_code('', '
Bus 001 Device 007: ID 04a9:1751 Canon, Inc.
')

sane-find-scanner shows
$this->bbcode_second_pass_code('', '
found USB scanner (vendor=0x04a9 [Canon], product=0x1751 [MG2100 series]) at libusb:001:007
')
But scanimage -L reports
$this->bbcode_second_pass_code('', '
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
')
lpstat shows nothing whatsoever.

also, on the cups page, When trying to access either the admin or printers page, I get an "internal server error"
my cupsd.conf looks like
$this->bbcode_second_pass_code('', '

')

Any ideas? Am I missing something basic?

Oh i should mention, the cups server is on a pogoplug (ARM) and I'm on an arch tablet on the same network

So I turned debugging on and looked at the log, and admin.cgi and printers.cgi both crash when i try to visit the admin page or the printers page. (signal 11)

After having the same Internal Server Error issue myself, I stumbled on the solution here: viewtopic.php?f=15&t=3264#p19708
