OT: a USB barcode scanner?
....g. after identifying the
USB device). I think this is a pure Linux-related question, it is
unrelated to the scanners (just as if you would attach 2 keyboards).
If you have a recipe for that, just let me know ;-).
One of the scanners I tried is this cheap scanner from dx.com:
http://www.dx.com/p/xyl-901-handheld-usb-wired-laser-barcode-scanner-black-yellow-286474#.WEvbKnUrI_M
It just works out-of-the-box when connected to a Linux-system.
Start "cat" and you'll see the scanned codes.

OT: a USB barcode scanner?
Hi, folks,
I'm about to go googling, but thought I'd ask here if anyone's using a
barcode scanner with CentOS, and if so, a) what scanner are you using,
and b) what, if any, software are you using to record what it scans?
<mutter, mutter, the serial number of every bloody h/d that we're asking
them to deGauss...mutter,mutter>
