The upcoming Linux 6.19 kernel cycle is expected to land initial support for USB3 with Apple Silicon devices.
Being worked on the past few months for upstream inclusion into the mainline Linux kernel has been patches for USB3 support on Apple M1 and M2 devices. Sven Peter has been leading the charge. These patches were updated earlier this month and now look good to go for making it into the next Linux kernel merge window.
@fdnomad @cm0002 @linux Asahi Fedora on an M1 MBP has worked for me, but so far I’ve only used an external monitor over HDMI. Type C dongle is fine for my keyboard and webcam.
