D2522UK Usb Drivers

Hey guys i have a Packard Bell D2522UK PC which i cannot for the life of me find the correct USB drivers for.

I have a fresh install of windows 7 home premium, and the USB keyboard + Mouse work fine, when i plug in my external hard drive or blackberry the system a) doesnt detect it and b) if it does detect it, it only runs on USB 1.0 *(ideally id like at least USB 2.0!)* I have searched everywhere for an answer, with no luck at all.

Any tips? Hints or information would be great!

Many thanks

Eddy
