Hi,
I have one question regarding to the UMDF driver for USB Device.
The USB device has an USB INput device and HID device. I used to write a KMDF lower filter driver of the USB Input device and it works fine until now. However, can I do the same thing using the UMDF?
Thanks,
Marshall
No, you can’t have a lower filter umdf driver below a km stack
