Thanks Doron,
If all the endpoints are on a single interface, then at which level of the
HID hierarchy would new driver be? Would it be above the HIDClass driver?

If each interrupt endpoint is part of its own interface descriptor (ie
10 interfaces on your device) then this will work. if you want all 10
endpoints on one interface, then you will have to write your own driver.
Hidusb.sys only knows how to read from one interrupt endpoint /
interface.

The new device conforms to the USB HID class specifications but has this
additional feature of multiple interrupt endpoints. I am not sure that
the
existing HIDClass driver available in Windows is capable of handling
this or
do I have to write a driver on top of HIDClass driver. Also is there any
other approach to solve this problem?

Is this new device conforming to the USB HID class… If not then you
may require to develop your own driver

Subject: [ntdev] Interface for USB HID device with multiple interrupt
endpoints
Hi,
I have to develop the software interface for a USB HID device that uses
multiple(upto 10) interrupt endpoints in order to increase the
throughput of the device. Can this specific requirement be addressed by
the HID Class Driver provided by Microsoft or do I have to develop a new
device driver? In case a new driver has to be developed, would it be a
kernel mode client driver above the existing HID Class Driver?
Thanks in advance,
Regards,
Reema
