Hello,

 

I've been trying to run the same70 in USB host mode for quite a while. I have already managed to operate the USB mouse in host mode, but I have not managed to get a keyboard or CDC device to register via the USB interface. As soon as I plug in a keyboard or a CDC device, it runs until uhc_enumeration_step6, after which the communication breaks off. Has anyone had similar problems and knows the solution?
