speculative:
it is well known that conexant wants to sell proprietary drivers for
their chips (linuxsant), maybe they invented little cryptographic
authentication to check if the device is accessed by licenced drivers.

did you see any random data in usb comms? ill check too.

ive hearded of the usb sniffers, the scanner and camera teams seems to
use them too.
which shall i use?
are you sure therere no databooks around? anyway the firmware is closed
source... maybe it could be "disassembled" with a arm devsuite...

done so far:

hardware analysis:

serial wg13142db104927, pcb says rev 5
chips aasembled:

"netchip net2280 rev 1a-lf" layout looks like its attached to usb port,
~ does it have an arm core?:
"isl 38801k",
"isl 3686air",
"isl 3048ir",
"ti cl125 39k",
"(w)inbond? 24lc64" some flash memory?,
"atmel 338 25640n".
"isl 6414ir"

building cvs under 2.4.26: failed due to my "icompetency":

after simply cp makefile26 to makefile24:

i must learn makefile scripting.
