According to Phoronix, Linux 6.2 will support a USB4 connection/wake on disconnection. The patch submitted by Greg Kroah-Hartman has been merged into USB-next and will be incorporated into the mainline when the Linux 6.2 merge window opens next week.
This feature is disabled by default but can be toggled via the new “wake-up” property under the USB4 interface with sysfs support, a small improvement to optimize the experience.
In addition, Linux 6.2 will support Intel Razzle Solo, Sony PS4 grip, as well as initial support for Apple M1 Pro / Max / Ultra Mac devices.
