Hi there,

I think there is a problem in the way you want to do ansyc non-EP0 Xfers:

in BeginDataXfer() you use the fixed-statement for the lpInBuffer, lpOutBuffer and lpOvLap that you pass to DeviceIOControl. The documentation (msdn.microsoft.com/en-us/library/f58wzh21.aspx) states: "The fixed statement sets a pointer to a managed variable and "pins" that variable during the execution of the statement.". After the async call to DeviceIOControl, the pointers are unpinned, and by the time the transfer performes hardware access, the pointers may be something else....

I think you should consider redesigning your async data transfer...

Best regards,

Detlef
