Merge tag 'usb-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/…
…git/gregkh/usb
Pull USB/Thunderbolt updates from Greg KH:
"Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
Nothing really major in here, just lots of constant development for
new hardware. Included in here are:
- Thunderbolt (i.e. USB4) fixes for reported issues and support for
new hardware types and devices
- USB typec additions of new drivers and cleanups for some existing
ones
- xhci cleanups and expanded tracing support and some platform
specific updates
- USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio,
spi, and i2c drivers for that type of device (all acked by the
respective subsystem maintainers.)
- lots of USB gadget driver updates and cleanups
- new USB dwc3 platforms supported, as well as other dwc3 fixes and
cleanups
- USB chipidea driver updates
- other smaller driver cleanups and additions, full details in the
shortlog
All of these have been in the linux-next tree for a while with no
reported problems"

This commit may have introduced some incompatibility with the latest Lenovo X1 laptops, specifically X1 Carbon Gen 10 / X1 Yoga Gen 7:
After updating to kernel 6.7 the USB connection on my Lenovo X1 Yoga Gen 7 became unstable. For instance, when I try to use my PlayerOneAstronomy Uranus-C camera in its native resolution, it fails to initialize and is stuck in an infinite reset loop. The respective message in the kernel log is:
kern :info : [Feb15 18:44] usb 4-1: new SuperSpeed USB device number 2 using xhci_hcd
kern :info : [ +0.018551] usb 4-1: New USB device found, idVendor=a0a0, idProduct=5850, bcdDevice= 0.00

[...]
I contacted the software developer of the imaging programme I am using and after we established that it is not a bug in the software I contacted the device manufacturer. I also updated the BIOS and firmware to the latest available version. The bottom line is, that all evidence points towards an incompatibility with the USB controller that has been introduced with this kernel commit: this commit happened between kernels 6.6 and 6.7 and changes were made in many places relating to USB and XHCI.
