How can I process both bulk pipe and interrupt pipe of USB?

Hello,

I'd like to process both bulk-pipe data and interrupt-pipe data.

I have made the scenario for this as follow:

1. User app starts bulk read operation with overlapped operation and
finishs after bulk read operation done.

2. For interrupt pipe read, user app requests IO control for creating
a system thread that sends URB to USB interface and saves
some of received data to buffer.

3. After creating the interrupt process system thread, user app starts
read operation of received data from interrupt pipe with overlapped
operation and finishs read operation after data copy from Step 2's
buffer.

4. In user mode, for bulk read and interrupt read, 2 independent threads
are running for each operation.

Is there any problem in my operation scenario?

Your comment will be appreciated greatly.
