StarTech HB31C2A2CB is a supported hub (tested)

[loupiote]

I found that this hub (not in the supported list) works with uhubctl (tested on Ubuntu):

StarTech model HB31C2A2CB

USB ids:
Manufacturer: 14B0
ProductId: 013F
Rev: 0003

Note: On the device itself, it says "Rev 2"
I only tested with this revision, but I assume other revisions will work too.

The Hub has 2 USB-A Ports and 2 USB-C ports. Only the USB-A ports are power-controlled with uhubctl

I tested it with a ledger device which i needed to power-cycle. I could see it reset as expected.

log:

• uhubctl --action cycle --delay 0

Thanks for your submission, added it to the list.

I've noticed that with this hub (and some others), USB 2 devices (or USB 3 devices connected via a USB 2 cable) power off correctly, but USB 3 devices do not (there are no errors, but the devices disappear and re-appear on the host but the power / LEDs on the device never drops).

I think any testing / adding of hubs to the list should include testing both USB 2 and USB 3 devices, so that any differences can be noted.

Actually I've got it working. The only way the power turns off to a USB 3 port is if every USB 2 and every USB 3 port is powered off. Then the USB device successfully powers down. I guess that makes it a bit like the Raspberry Pi 5 behaviour?
