I wonder when it comes to a driver-managed queue, what’s the diffence
between those two? Someone told me it is better not to mix a driver-managed
queue and a device object’s queue, especially the one created by
KeInitializeDeviceQueue(…). True?

Thanks

Well it comes done to this if you have a device that can only do 1 read or
write at a time, use System Queuing. If you have a device that is capable
of doing reads and writes simultaneously, then use driver queuing.
