USB Problem

[lpollsnoop]

Dell 8300
Windows XP home

When I try to download photos from a Canon Powershot a75 I get
a message 'unrecognized hardware found'

I bought a SanDisc CF card reader and it was not recognized at all by the system.

When I plug in a memory stick from an MP3 player the system does recognize
the device.

I have tried all of my 6 USB ports with the same results.

I have disabled the automatic powering down of the USB Root Hubs.

Delete the USB Root Hubs from the device manager, reboot. Post back with what happened.

SNG - thanks for the reply.

Deleting the Root Hubs had no effect.

There are no other USB devices attached to this system.

The camera used to be recognized -
