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.
 | 
						|
 | 
						|

 | 
						|
 | 
						|
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. |
