I've recently gotten a new USB drive, and the problem is, whenever I plug it in, it just shows up as an unknown device. It also won't install the driver. So, basically, I can't use my USB, which is obviously a problem. I've already tried a lot of solutions, and trying to use the troubleshooter promptly gives me an error (sdiageng.dll isn't valid or something). I've tried using the USB with other computers, works perfectly fine. I've got Windows 7 btw. Thanks in advance.
Note : I'm translating all the window names, like troubleshooter, etc. from Dutch, so bear with me.
