Yes, evdev is loaded and I see some /dev/input/event* nodes.  The unique
ones for this device (that show up when I plug in the device) are event3
and event4.  Also, I see mouse1 and ts1.

In /dev/input/by-id, I see:
usb-Cypress_Cypress_PS.2_Keyboard-event-{kbd,mouse}
usb-Cypress_Cypress_PS.2_Keyboard-mouse

I tried your "od -x" trick on each of these to no avail.  I pointed the
barcode scanner at some arbitrary barcodes, and it beeped and turned off
the red light, but nothing appeared on my screen as a result of the "od -x".

Are there other possibilities to consider?

Thanks!

Andy
