USB problems after using bootcamp

Yes, I followed all the previous steps from when I first insatlled windows. Now they don't show up. I've tried assigning a drive letter using the command line and the Computer/manage/computer management/disk management. Both methods state there is an error as they can't find the specified file. the first time I used the computer mangement tool it said that my console version was out of date, even though I had ran all the windows updates, I did however have another update today but that still didnt manage to solve the problem.

I've tried using a driver fixer from windows, but again still didn't work.

P.S. When I plug in the USB stick, the computer does recognise them and install a driver, it then tells me that the driver was installed correctly and is ready to use etc. but there's nothing in the computer section 😟

I can't do a repair install there's an error saying unable to crete folder whilst copying temp files, I've just reinstalled windows and inserted the OS X install disk, installed all the drivers and again still no USB showing in my computer and still un able to assign drive letters.

Ok then, I'm trying to get round this error and use the windows disk for repair. I'll let you knnow how it goes and if it works. Thanks a lot for your help so far though!
