Desk Pi Lite Front USB Support

juansif · September 14, 2022 at 12:23 AM

Hello, although I have used this LibreElec for sometime, I have never really tried to use the ssh terminal. So here is the deal, I just purchased a Desk Pi Lite case for my Raspberry Pi 4 with has 2 USB ports on the front. According to the manufacturer I have to install the driver (http://github.com/DeskPi-Team/deskpi_v1). However with I login to my pi using PUTTY it says file could not be found. I did not change the login for LibreELEC it is still the default stuff. Is there a way to manually install this driver into LibreELEC.

Thanks

^ that's the install script adapted for LE quirks and locations .. no idea if it works or not.
