Bluetooth and USB not working in RetroPie

There haven't been any significat updates recently, current version was tagged on Sept. 8 (4.7.19) and RetroArch had the same version since July. You may try and checkout the version before (4.7.18 was tagged in August, commit b8e) just to see if any changes before 4.7.19 have any effect on your installation.

This is where my noob starts showing. How do I get that to download and install?

Assuming a fresh install, you'll need to use some command line commands:

cd $HOME/RetroPie-Setup
git fetch --unshallow
git checkout b8e5974

this will get you version 4.7.18, which you can use to perform an install.
To get back to the current version:

cd $HOME/RetroPie-Setup
git checkout master

@mitu ok thanks, I'll report back.

@mitu Well, It all seems to work correctly. Even the Bluetooth installed and I was able to set the udev rule for 8Bitdo. The only odd thing is when playing a SNES rom on the default emulator I had to press the buttons twice on the 8Bitdo controller for it to register then it would work fine until a screen changed then would have to do it again. There was no lag in the joypad, it was recognized and preformed as it should. Let me know if you want different logs also.

I don't see any differences between the logs - it's the same version of RetroArch as before and the input related log messages are the same. You can update to the current version and see if there's any change.

Ok, it shows everything updated. The joypad still works and the 8bitdo works but requires extra button presses for it work correctly in both emulationstation and retroarch. It was doing this in 4.7.18 also. It's like the 8bitdo has a delay at first. I remember earlier in the revisions that when you first entered emulationstation the menu would jump several spaces opposite the direction pressed then work perfect. I read that was a normal thing with the 8bitdo on bluetooth.

@mitu I have to nuke the current setup and start again. Retropie crashed when starting twice and now the Bluetooth 8Bitdo stopped working like before when I went into the setup menu to look for themes. I can't get the 8Bitdo to reconnect now so I'm starting from scratch. I think installing a theme may have broken something.

@mitu So it seems that after I install a theme the 8bitdo and keyboard stop working after launching a rom. After that I have issues reconnecting the 8bitdo and getting it to work at all. I've Uninstalled the theme and still have issues until I do a complete format and reinstall of Ubuntu and Retopie 4.7.18.
I'm at a loss now. I can't think of anything else that would be causing all these issues unless it's Ubuntu 20.04 and something with both sets of hardware.

mitu

Installing a theme shouldn't cause an issue with the gamepads working. There's something else that's causing the issue, but I'm also not sure what it can be.
Since the BT connection is managed entirely by the OS, I don't think it's something related to RetroPie. Maybe there have been some updates in the OS and you need to re-pair the controller ?

@mitu I'm not sure how to describe it. I've tried 3 different versions of Ubuntu and Pop OS and they all do the same thing after installing RetroPie. It will crash once when starting for the first time then work fine. The 8bitdo buttons don't program correctly the first time but will all map the second time. Then after I run a rom it stops recognizing the 8bitdo or it won't even load the rom and just locks up the system. The bluetooth stops responding on the OS desktop as well. I'll try to look into the 8bitdo firmware and see if that is an issue. I'm at a loss at this point.
