RPI4B + Inateck HB2025A - cannot power off #589

Closed Matsuo3rd closed 2 months ago

Hello,

I cannot get RPI4b + Inateck HB2025A switching off ports. I purchased HB2025A knowing that RPI4 ports are ganged. I plugged HB2025A on USB 2 RPI port (following guidance from https://github.com/mvp/uhubctl/issues/451). I plugged the USB device (a Sony gamepad) on hub's port 2 (following guidance from aforementioned link).

sudo uhubctl -a off -l 1-1.3 -p 2 Does not power off the port

However performing a power off on RPI4 USB port hosting HB2025A hub before make subsequent calls powering the USB device work.

So the following sequence works:

sudo uhubctl -l 1-1 -a cycle
sudo uhubctl -a off -l 1-1.3 -p 2

... but this resets my whole USB chain which I am not happy with (others USB devices plugged in).

Some context:

uhubctl -v

Note that Inateck HB2025A is listed as having some weird issues e.g. USB2 only compatible, so I am not surprised you have issues with it. Perhaps we should remove it from the list...

If you want relatively cheap and reliable solution specifically for RPi4, I would recommend getting UUGear Mega4. It was specifically designed to support stacking on top of RPi4, per-port power switching, USB3, and is quite cheap.
