USB Key dead after Knoppix install? Please help me!

[detsiwt]

I got Knoppix to work on my flash drive last night, went to bed, and now my USB Key does not work.

I plug it in and the power lights do not even turn on and nothing happens when I plug it in.

I know my USB ports are good because I am able to plug other devices in.

I bought the key yesterday and it worked fine up until the point I went to bed.

Please someone help!

Addon:

I've tried the key on another PC and still nothing.

I do not know if this helps but it's a SanDisk 4gb micro cruzr
