I found a way to improve USB HID/Mass Storage compatibility with some motherboards. I would like to ask you to check if there are any problems because of this. If successful, if you didn't have MSD working, it may work after this change.
<!-- more -->
Please check this on your configurations: whether HID/MSD worked before, whether it works after the patch. I will be happy to hear about any changes (both positive and negative).
Run on Pi-KVM:
```console
rw
sed -i -e 's|^dtoverlay=dwc2$|dtoverlay=dwc2,dr_mode=peripheral|g' /boot/config.txt
reboot
```
This can be easily undone if problems occur.
