This is so weird....
On my Device Manager, it shows that USB flash drive as "Other Devices" and under that, it shows "USB Mass Storage Device" with yellow question mark.....
Now, I borrow a USB flash drive from friend next door, I put it in and it works fine. Under device manager, it show correctly under "Univeral Serials Buss Controllers" (USB) and under it, it shows "USB Mass storage device"
The computer next door can handle anything. any usb will works automatically, external HD, external dvd burner...you name it. it will automatically install drivers and show "your device is ready to use"
Both computer are the same specs.
