I am using Windows 7 x64 and an arduino uno. It uses the pc's power source to power up some LEDs and it's connected to the pc via USB. It works perfectly fine while the pc is running, but whenever I try to shut it down there is a blue screen and it restarts. That doesn't happen whenever I disconnect the arduino so it's clearly the problem.
I analysed the crash dumps and it shows me stuff like this:
On Thu 28.02.2013 21:48:22 GMT your computer crashed crash dump file: C:\Windows\Minidump\030113-20311-01.dmp This was probably caused by the following module: usbport.sys (USBPORT+0x16F4B) Bugcheck code: 0xFE (0x4, 0xFFFFFA800B6ADBD0, 0xFFFFFA800AC748D0, 0xFFFFFA80082A6C00) Error: BUGCODE_USB_DRIVER file path: C:\Windows\system32\drivers\usbport.sys product: Betriebssystem Microsoft® Windows® company: Microsoft Corporation description: USB 1.1 & 2.0-Porttreiber Bug check description: This indicates that an error has occurred in a Universal Serial Bus (USB) driver. The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system which cannot be identified at this time.
So there is some kind of problem with the usb-driver...
any ideas on what to do?
