Oct 28, 2026, 4:47 PMThe Asahi Linux downstream Kernel 7.2.12 has initial USB4 / Thunderbolt 3 support. It does not yet support the 2 features (PCIe and DisplayPort tunnelling) everyone expects. Tunnelling of USB3 and Host to Host (Ethernet over USB4) are working on all supported M1, M2 and M3 devices.
This means USB3 ports and integrated devices on Thunderbolt hubs might work. USB4 network speed is much slower than the theoretical 40 Gbps due to interaction between the Linux driver and the IOMMU (DART),
