Not working on the latest Arch Linux (Python 3.12)?
Just cloned the repo and tried boot-g12.py:

First, I reduced the block size for the failed function call back to the default 64 bytes:

I tried to play with block size (AMLC_AMLS_BLOCK_LENGTH, AMLC_MAX_TRANSFERT_LENGTH, and AMLC_MAX_BLOCK_LENGTH) for the above error to no avail. There is also another error that I'm getting:

So it is mostly dev.getBootAMLC and dev.writeAMLCData throwing errors on me now.
I'd like to check if this is my own system issue, or if this is an Arch issue.
Can you precise on which usb controller model you are running? Can you run lsusb -vv ?
Upgraded the system today and the issue disappeared. The kernel was upgraded from 6.8.8 to 6.8.9 so maybe something was not right in the previous release.
