Windows has stopped this device because it has reported problems.

Well I have a MIDI keyboard instrument that was working on my Win7 x64 machine, with proper drivers, and then it just stopped. I get this error message "Windows has stopped this device because it has reported problems. (Code 43)". Oddly it works on an XP machine I tried, while it fails on other Win7 and Vista machines I've tried. Could this device have gotten damaged? If so, is there any way to have it detected in Win7, considering it works in XP still?

If anyone is wondering it's a Yamaha ez-250i keyboard instrument.

Also, I used a 12 foot usb cord. I remember reading something about USB only being designed for 6 feet or so, could this have damaged the device? Thanks.

have you confirmed that the Yamaha is compatible with Vista/win 7? Chances are the USB cord has not damaged the device but may be the reason it is reporting problems.

Yep. I downloaded official Windows 7 x64 bit drivers and it was working fine before. Also, I've tried about four different USB cords.

Well after reformatting my computer it has seemed to detect the MIDI keyboard correctly now. I'm wondering if this was brought about because I do not safely remove the USB device. If this is the case and the driver gets corrupt, how could I delete the driver, given windows detects the device as a malfunctioning USB device, still? Thanks.

You could try uninstalling it from the Device Manager then re-installing it from scratch and see if it starts working again.

On the other question: using a longer USB cable doesn't really damage the device, but can make it work not properly (it happened to me with a scanner and with an external HDD: in both cases changing the cable for a shorter one revived the devices which weren't working) so if you mind a suggestion I'd use the shorter cable possible.
