BadChecksumErrors

[mattchrist]

I'm running into issues trying to backup my PineBuds firmware. When running backup.sh, I get checksum errors:

com is: 0
1
This tool assumes your buds are the only thing connected and are enumerated {right,left} order. YMMV
Right bud is at 0
Left bud is at 1
Please disconnect and reconnect the bud on the right

Do you have any suggestions how I might get this working?

Thank you!

This is more of a bestool issue, could you open an issue there? I'm in the process of refactoring that tool, but it shouldn't affect you right now.

Also, when you open an issue here, please post the output of lsusb with the PineBuds plugged in.
