Hi Arun,
(I've to work on my email setup - it seems to be drastically flawed :( I
didn't notice this hadn't gone through till now.)

Hello,
I'm trying to access barcodes scanned and saved in a scanner's flash
memory. The scanner, Opticon's OPN 2001, connects via a USB cable
(which rather niftily also charges its battery), but the interface is
actually serial rather than "native" USB. Opticon scanners seem to be
supported as of Linux kernel 2.6.29
A quick glance at the opticon.c code looks like it is a driver which only
gives generic serial port like access to the scanner (makes life of a
programmer simple by not having to work with USB).
Makes sense.
You will have to ask for
the protocol from the manufacturer to talk to the device to collect the bar
codes stored in the flash memory.
I was hoping that wouldn't be necessary :(
Update: Opticon tech. support has been responsive on this, much to my
surprise :)
Some manufacturers might not give it (Of
course they will have free windows software and drivers for it) . For an
other manufacturer I had to sign a NDA and fax it to the USA before they
gave me the protocol for a DAQ device...
Looks like I'm stuck with a Windows machine for much longer than I'd
hoped would be the case.
Update: They've reused the Symbol CS1504 protocol. The only (!) problem
now is that the Opticon device doesn't respond, which is a driver issue,
acc. to the Opticon support guy. There also seem to be some ongoing
issues with USB serial code, from this Linux kernel thread:

Thank you,
