[sane-devel] Re: SANE driver for NEC Petiscan scanner

[m. allan noah]

TIS is teco image systems. 2ax000 must be part number. next is date code.

there is a little hp that uses this chip (photo 1000 iirc).

your best bet is going to be usb sniff from windows, and compare the data 
to what is used by the other teco backends, just on the off chance that it 
is similar or encapsulated version.
