The device is called a "CUE CAT". And yes, you can get them to read barcodes. First you have to remove the serial EEPROM that contains a Unique Identifier that it attempts to send back to DigitalConvergence (which is of course out of business, but still).Then you have to hack about with the hardware some more to essentially get around the proprietary "encryption" that the cuecat does to all barcode output, which is nothing more then a cheap obfuscation scheme (security/encryption should be left to people who know what they are doing, DigitalConvergence need not qualify). This involves cutting particular traces and adding a jumper line halfway across the circuit board. Good luck.
