I installed Haiku onto a USB memory stick, and have been running it for a few days. It works, but only in the USB-A port. Boot fails if the same memory stick is connected to USB-C.
Yes, this memory stick has both A and C, one connector in each end. Great design. Fits both types of port. But haiku must use A for booting on my ThinkPad.
ChatGPT explains that USB-C is Thunderbolt, and not compatible with booting Haiku on ThinkPad. C only gets to the fourth square on the splash screen, and gives an error message that it could not find boot partitions.
