Routine Description:

When I play the usb device,get BSOD titled “41 Must_Succeed_Pool_Empty”
Could you advice?Thanks a lot.

Well lets start with this: “Callers of IoBuildAsynchronousFsdRequest must be running at IRQL <= APC_LEVEL.”. First fix this issue and the get back to us. By the way do you ever bother to free the IRPs that you are allocating with IoBuildAsynchronousFsdRequest?

Turn driver verifier on. Build against prefast and fix all the errors.

When I play the usb device,get BSOD titled “41 Must_Succeed_Pool_Empty”
Could you advice?Thanks a lot.
