USB-HID-HOST on STM32F407 / STM3240G EVAL

Question asked by l.s.002 on Aug 15, 2016
Hello,

I tried the example on the evaluation-board STM3240G-EVAL with the USB-HID-Host in Standalone mode HS and FS from the CubeF4 examples.

The mice is recognised properly.
The keyboard seems to work not properly.

I tested different keyboards and when I plug them in, I can say, they are recognised as a keyboard because the screen shows me that a keyboard is active, but when I press a button on the keyboard, there is no further reaction in the software...

What is the problem with the protocol?
Do the keyboards have to fullfill any special conditions to work properly with the evalutaion-board?

Thanks a lot!
