I have a Dell Studio 1745 running windows 7 64 bit. I did a factory restore of the laptop as I was experiencing slowness on running applications. Everything is running ok now, but I have 1 device in the Device Manager which isn't recognised.
It says USB Device Controller and the hardware id's are
I can't find any information on this and can't find a driver using the Device Manager. I think it may be the built in SD Card reader, but I have no information on the manufacturer of it (laptop is around 3 years old)
