The USB ports on my PC have stopped working for certain devices only. Devices
such as my ipod, scanner & a card reader which used to work fine, no longer
work on any port and a new camera does not connect at all. Yet other devices
such as my bluetooth receiver, broadband DSL box & an old card reader still
work fine on any port. If I plug in any of the former devices it tells me
that an unknown device is connected. I know of no reason for this as I
upgraded to SP2 after this started happening. Can anyone help? Thanks. (P.S.
I am not a techie so please type in words of one syllable!!)
May be this means that USB connector no longer supplies enough power.
No idea how this can occur (of course, if these high power devices actually worked before...),
try to connect them thru a powered hub.
