We can't just add devices without any evidence of vbus off testing.
Please tell how you tested vbus off support.

@mvp I followed the instructions in the readme for new devices, checked lsusb -v:

Bus 003 Device 025: ID 2109:2812 VIA Labs, Inc. VL812 Hub
...
Hub Descriptor:
  bLength               9
  bDescriptorType      41
  nNbrPorts             4 # 1-3 are USB-A, 4 is ethernet
  wHubCharacteristic 0x01e9
    Per-port power switching
    Per-port overcurrent protection
    TT think time 32 FS bits
    Port indicator

Then checked that sudo uhubctl -a {on,off,cycle} -l 3-1 -p [1-3] -f (where 3-1* was this hub) worked (Actually turned off the devices plugged in - mouse, keyboard and charger).

*found this by sudo rg 2812 /sys/bus/usb/devices/*/idProduct, you may want to add a note on this in the readme because lsusb doesn't show the part after the bus number, only the bus number.

Lmk if you want me to record a video proving this.

Thanks. Of course I don't need video. But best test is voltage dropping to zero or phone stopping charging when port is off

Reason why I want this confirmation - all too often, when hubs advertise per port power switching, uhubctl is usually able to turn port off which always stops data communication. But some hubs don't remove power (aka VBUS) upon port turn off. We don't want to add such devices.
