USB2.0 4 MiniSD memory "unknown device"

I just got a 512mb SanDisk MiniSD and mobile card reader/writer usb2.0 i am using it for my moblie phone. when i plug it in my usb ports it comes up as unknown usb device i have been searching forums and sites for 2 hours D/Ling drivers and what not. i am running a asus A7N8X-E mobo and they have worked for everything else like joysticks mouses headphones and what not... i have found on the asus website that other people are having the same problem with USB... please if anyone has and info on this issue it will be much appreciated and if i figure it out i will be sure to post

 

Try a different USB port (sounds stupid, but I've seen bad ports before that work, yet don't).
Check the BIOS to see if USB is configured
Flash the BIOS (this is the 3rd time I've recommended flashing BIOS today, but its often overlooked)
Try every driver you can find for it, even older ones. I've even used drivers for SIMILAR devices to find that one will work.(often its just a few lines of code that makes a driver work for one device and not another)
Try it on another PC if ones handy (just install the driver temporarily). Try to rule out if its your mobo/BIOS/Windows config

Good luck
