Device Has Malfunctioned.

[Win]

I bought a new computer recently, and I haven't been able to use a Wireless adaptor with removable storage. Whenever I plug a USB storage device in, it doesn't load and says 'This device has malfunctioned'.

If my Wireless adaptor isn't plugged in, then any USB storage device works fine, as normal.

I have tried multiple Wireless adaptors, with the correct drivers, and it still doesn't fix the problem.

I am using Windows 7 32-bit.

Thanks in advance.
