I have bought this keyboard and mouse combo quite some time now from CompUSA, just recently this Sunday, the keyboard stop working! I thought it needed new batteries as always, so change the batteries the the software pickups the signal from the keyboard, but when I try to punch in the passkey it doesn't work!!! Why??? I tried the wireless link applet at the control panel and detects it as a CSR-bc2 device rather than Microsoft Keyboard, anyone has this type of problem yet??? I'm not really concern on how XP should detect the device but as long as I can type again so I can connect my keyboard back. HELP PLEASE.... glady appreciate it.
