Is this documented anywhere? Or how did you figure this out?
The other person I've seen report this issue was also using the same board, so it could be an issue with the chip. https://github.com/flashrom/flashrom/issues/237
I got the board recently, and I believe it's a recent revision of the board. It's an FT232H board from Adafruit. It's also using the FT232HQ.
As for SW, I'm running Arch Linux, with Linux 5.17, libftdi 1.5, and libusb 1.0.26.
I also have another board with an FT2232HQ on it, I could test with that if that would be useful. If it works, that wouldn't really say much, but if it didn't work it might point to an issue in the libraries being more likely.
