Exclamation marks ?

Hi.
Just reinstalled Windows 7 Ultimate 32bit.

Now I see exclamtion marks for 2 USB adresses in Device Manager.

I have tested with new drivers for the 2 USB addresses in focus, but
they are still having the issue.

I wonder if it is a defective USB sticker, as I recognized during a boot, thet
I got a message telling, that an USB overload had occured. After having unplugged
the sticker, I could boot again.

But the USB sticker is still in fuction

Hi friends.

Thanks for replies.

I downloaded the Driver Update Utility, and found the drivers to be ok.

After I unplugged an USB Hub, the issue dissappeared.

I think the HUB has been fried.
