I have used both a compiled flash and one downloaded on the github along side the OS and in both cases I get the same error with my USB plugged into my PC or 3d Printer.

What does dmesg command says? I had similar problem and it appeared that USB was shut down due to EMI produced by my PSU.

I currently don't have the board as our dev has it atm. The issue for me ended up being I needed to flash the board without the CB1 board plugged into the manta for it to properly take the firmware. After that it worked fine and the serial pulled up.

I have no idea why this worked for me but... try ls /dev/serial/by-path/

This was the only way I could find a path, not sure exactly where I found this, I had been struggling for over 2 days to get a usable pathway but this for some reason worked!

I have noticed that if i installed a 32 bit OS image it appears normal

This is likely due to using a distro that has the known bug that causes this exact issue. You can find more information about that here https://klipper.discourse.group/t/debian-bullseye-bug-causing-klipper-to-no-longer-find-the-printer-board/8231

That is strange, now i have no issue with both cm4 and cb1 using latest os image. Both are working fine.
