Dell Desktop USB not working (need driver)
I'm getting this yellow exclamation after a clean Win 7 install using the bios mod/OEM activation method. I think the yellow exclamation is for the front side and back side USB ports because all of them are not working. Nothing happens when I plug in a USB thumb drive. Alternatively, it can be for the Apple HD Cinema Display 23' USB ports at the back of the monitor but they are working properly.
My system specs are as follows:
Dell Precision 390 with SLIC 2.1 bios mod
Win 7 Ultimate x64 SP1
Intel Q6600 quad core cpu
Intel 975x chipset (with Intel 9.4.0.1017 chipset driver installed)
I searched the Dell support page but it's useless because my setup was made for XP. Any suggestion? Thanks!
