devices "Barcode Reader" / Mouse,Consumer Control SOLVED

What are these "Barcode Readers" I get from xinput?  I don't have a barcode reader and as far as I can tell, no barcode reader software installed. Thanks!

Sob story: I was vainly trying to find the model # of my old logitech mouse; the mouse and a no-name PS/2 keyboard are attached by USB, but through converters (cables) so they only use one USB port (mouse: USB->PS2->USB-combined and keybd: PS2->USB-combined)

Solution: adapter shows up as a bar-code reader for some reason.

$ xinput list 

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Barcode Reader  Mouse                   	id=9	[slave  pointer  (2)]
⎜   ↳ Barcode Reader  Consumer Control        	id=11	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Video Bus                               	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ Barcode Reader                          	id=8	[slave  keyboard (3)]
    ↳ Barcode Reader  System Control          	id=10	[slave  keyboard (3)]
    ↳ Barcode Reader  Consumer Control        	id=12	[slave  keyboard (3)]

That converter is detected with the name "Barcode reader".

I think you're right, though that's a strange name to come up with for an adapter, and will mark this solved since I did the obvious and plugged the mouse into it's own USB port and get the same result from xinput, except for

⎜   ↳ Barcode Reader  Mouse                   	id=9	[slave  pointer  (2)] (same...)
⎜   ↳ Barcode Reader  Consumer Control        	id=11	[slave  pointer  (2)] (same...
⎜   ↳ Logitech USB-PS/2 Optical Mouse         	id=12	[slave  pointer  (2)] (new) 

...so now the Logitech mouse shows up along with the imaginary "barcode" mouse.
