Aegis,If i understand correctly;
1. This device had worked in this computer correctly before?
2.It is not "files" that you are looking for in "my computer" it is the presence of a "removable device'--when it is plugged into "any" USB port is there any reference to "something" removeable in my computer?
3.What does your device manager say about your USB hubs?
4.Does any other device work in any USB ports? IE: printers,scanners,mouse,keyboard,card reader,etc.?
5. Are your USB ports "enabled" in your BIOS?
