I write a driver, which attch the tcp,udp,rawip device,that i used to get the process of the transport endpoint, but on win7 it blue crash while tcp connect sometimes,however i only use IoCallDriver
I believe nobody could tell you the BSOD reason before getting more information about your driver. But I can recommend you to use WinDBG tool to debug your code. You sould attache a debug machine with WinDBG tool via 1394 or serial port connection to your
test machine with the driver your developed.http://msdn.microsoft.com/zh-cn/windows/hardware/default.aspx http://whqlcn.wordpress.com
