No access to USB devices

[couissent]

This morning none of my USB devices were working - I have a printer, scanner, external HD and webcam. Have checked lsusb, and this is what I get:

Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

Any ideas about what I can do to get them back?

Not really without some more info

Did you do any upgrades?

Also, have you tried the live CD and stuck in the external HD? If that doesn't work, you may have to consider faulty hardware...

Probably not a faulty hardware problem. There is a similar report at:

Re: No access to USB devices

Are you using a USB Hub, or are these devices connected to on-board USB ports?

Re: No access to USB devices

Thanks everyone. I used a live CD, but still couldn't get access, so I was putting it down to a hardware problem.. I was not getting access to either on board USB ports or to a hub.

Then, I booted up on the following day, and all was well, and has continued to be so since! So no problem now, but absolutely weird that on Sunday on none of the many occasions on which I booted up (once with a live CD) was I getting any access.

But many thanks for your help - very much appreciated!
