Hello:
I am a newbie in this please, bear with me. I want to develop a USB-Serial driver but Windows native solution doesn’t include a call to inform to the device that the application requires enabling the hardware flow control in the serial communication.
We need a class specific request (using EndPoint 0) informing that the device must enable the Hardware flow control.
Now my question is: Should I use a filter driver above or below usber.sys, develop a KMDF driver or a UMDF driver will do? thanks!
