Question USB External Hard Drive not detecting

Bossman is trying to connect his external 120Gb 2.5 IDE Hard Drive to his PC.
I tryied the USB Connection, and the light turns on, but the drive is not detected. I have drive this on all the USB ports
I connect the drive in my PC, and it works with out a problem.
There is nothing wrong with the USB as there is as lot of other devices connected too it.

Now I connect the drive via firewire on bossman's PC and it works.

Now Bossman has a crazy amount of USB devices on this PC.
1x Keyboard / Mouse
1x PDA sync cradel
1x Bluetooth adaptor
2x Chinese writing tablets.
1x Printer
1x USB hub.

Would it be possible to say that all this USB devices are drawing too much power?

Try this:
A computer that is running Windows XP cannot detect a USB thumb drive, an Apple iPod, or an external hard disk drive
