I have a barcode scanner (UF-101 PS/2 keyboard wedge). Was working fine one day, the next it won't read anything. (Shines the LED light on the barcodes, but won't "read" them).
So I bought a new scanner (POSX Xi200, also a PS/2 keyboard wedge), but it doesn't work either. Tried both on a different machine (should've tried this first) and both work fine.
So evidently the problem is with the computer, not the scanner. Any idea what could be wrong?
Some of your drivers/options could be messed up; try going into Device Manager and clicking "reset to defualts". Otherwise you could just reinstall Windows.
Seems to have fixed itself... I ran Registry First Aid, re-seated the PS/2 plug a couple times (with power off, of course), then re-started the computer. Maybe a pin was bent or corroded, or maybe there was a driver conflict that RFA cleaned up. Whatever, seems to be working now.
