    Hi I have a 1.66 Intel Core Duo Mini with 1.25GB RAM. This problem started a while back and I've been working around it but now its becoming a hassle. The Mini will not recognize USB device connected to it other than a keyboard (which I have a mouse connected to) . I have a 1TB WD USB Hard Drive, which has its own power supply, a USB Wireless LAN Card, Canon MX 860 Printer - none of which appear in the System Profiler. My Bluetooth is even showing up as Not Available now. I've tried isolating each device with no luck. Tried using a Self-Powered USB Hub… Anyone else expereinced this? I've tried re-installing my OS - nothing seems to work.

    Sounds like a logic board issue to me. Might need to take it to an apple certified technician...

    Good luck

    Bluetooth is on internal USB. Is it listed in the system profiler? Could be bad bluetooth board is killing all the USB.

    If possible boot from another disk to check its not software.
