Hi Experts,
I have a usb HID Keyboard,and I want to write data to the Keyboard device.
Through HID.sys,I write a application for above purpose,but always cannot connect to the device.
Could you advice?

You cannot open the keyboard from user mode. If you can alter the
device’s firmware, create a 2nd top level collection and read/write to
the keyboard through the 2nd TLC.

Hi Experts
Thanks Doron.
But I find software Busbound can write data to my USB HID Keyboard.
How can Busbound?

It probably sits at a lower level in the driver hierarchy…but that is
just a guess, I don’t really know.

Actually, you can probably open the keyboard if you only select WRITE
access. READ access will always fail.
