Kévin Redon 7f4f8983dd USBD: send empty packet when non-existing descriptor string is requested
Sometimes descriptor string 0xee is requested.
This is a mechanism used by Microsoft Windows to further identify the USB device.
Instead of stalling, as is the original code, leading to an USB reset, we send an empty packet.
I am not sure if sending an empty string would be better, but an empty packet seems sufficient.
