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.
Last week USB subsystem maintainer Greg Kroah-Hartman queued the various Apple Silicon USB3 patches into USB.git’s “usb-next” branch. With the code in the USB-next branch, it’s expected to be submitted for the Linux 6.19 merge window in early December barring any issues from coming up between now and then.
The Apple Silicon USB3 support builds off the Synopsys DesignWare Core USB 3.0 controller IP and with around 700 lines of new code added to the DWC3 driver code is enough to now have working USB3 for Apple M1/M2 Macs on Linux. These USB3 patches were previously carried downstream by Asahi Linux.
