[CentOS] 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>
