You have a Windows 7 machine.
You have a serial USB device, while the device reads data in a loop from a USB Serial device; you encounter a Bugcheck 0x000000D1.
Cause
The bugcheck occurs due to a synchronization problem in a code path where it completes a IRP while another is trying to process it.
Resolution
Workarounds:

1. Do not use COMMTIMEOUTS in your device, but Application level timeouts.
2. Move to WinUsb/UMDF.
3. Use the UsbSer source code which is released in the Windows Driver Kit (WDK).
