Switch on RP4b not working (worked on raspberry b+ first gen) #413

Closed nightyx closed 2 years ago

nightyx commented 2 years ago

Hey there, I have an unusual issue and did not find any solutions online.

I used uhubctl on a raspberry b+ first gen successfully with an Rosonway RSH-A16. Admittedly I didnt test all ports, but during development I could switch the ports on the 'furthest' hubs/ports (e.g. 1-1.4.4.4).

Then I upgraded to a raspberry 4b ("Raspberry Pi 4 Model B Rev 1.5") and now the switching does not work.

I have the feeling that the power-switching command is not send to the RSH-A16 hub. Example: I have two USB devices connected (one is a single usb lightbulb, and the other one is the RSH-A16 (containing more lightbulbs). When I turn off all ports (e.g. via uhubctl -l 1-1 -a 0), then the lightbulb turns of (as expected), however the other lightbulbs in the RSH-A16 hub are still turned on.

I tried using the repeated turning-off thingy (e.g. uhubctl -l 1-1 -a 0 -r 1000) and that did not work. I tried forcing the power-off with -f and that did not work as well. I tried using the usb hub on usb2 and usb3 ports. makes no difference.

Checking lsusb -v it shows, that the RSH-A16 supports power switching (at least, that the raspberry correctly identifies that the usb hub is capable of it).

I´m not sure what my mistake might be. As I said, the same usb hub worked on the raspberry b+ first gen before but now doesnt work on the 4b. TBH it worked once briefly and then after a reboot it did not work again. Any ideas on what to try to make it work?

mvp commented 2 years ago

What version of uhubctl you have? Anything older than 2.4.0 is not likely to work on RPi4.

mvp commented 2 years ago

Ah sorry I missed that you are using latest version of uhubctl - just make uhubctl -v shows 2.4.0-something.

As for reasons why it doesn't work, one possiblity is that usb2/usb3 port matching code may not able to find proper port pairing. You can bypass it with -e switch, but then you have to send turn off commands to appropriate usb2 and usb3 ports twice. Can you show uhubctl output when you turn off port which doesn't turn off? It should be displaying commands sent to usb2, then usb3 busses. If newer RPi4 changed USB topology, it may theoretically break. Actually, can you just paste output of running uhubctl without any parameters?

sorry that it took a while. i dont have regular access to the device atm. With regards to output when turning a port off.. yeah, I remember that it showed turning off two ports. I´ll get an output for that one next (forgot it this time). The output above looks normal, right? edit: although... is it normal to have 2-2.4.4 and 1-1.2.4.4 .. last one has one level more

edit:

pi@raspberrypi:~ $ uhubctl -v
2.4.0-30-g6f1c71d5

and we tried switching off one light with this command. However, the light is still turned on.

It seems that you have wrong batch of RSH-A16. I have tested mine and it defintely works great. However, some people are now reporting different kind of RSH-A16 sold, and it does not seem to work. More in issue #411. I will close this as duplicate I guess.

nightyx commented 2 years ago

Hey there, i finally got the chance to test the RSH-A16 on the old raspy again and it works! Thus I´ll reopen this one. So now I would think, as the usbhub works fine, that either the script or the raspbi4b is not working properly. It would be nice to make it work on the raspi4b, as my old b+ is acting up ;) So any idea on how to solve it for the 4b? Anything you would need from me?

Here are some outputs:

Its a very old raspberry b+ first gen Raspberry Pi Model B Plus Rev 1.2 Linux raspberrypi 5.10.63+ #1488 Thu Nov 18 16:14:04 GMT 2021 armv6l

pi@raspberrypi:~ $ sudo uhubctl -v
2.4.0-24-g61187d75

output of lsusb -v interestingly doesn't show anything related to powerswitching, but the output itself looks way different than the one on the raspy4b, so I guess it's due to the very old linux version / version of the lsusb package ;)

I just did an apt-get upgrade/update on the 4b, but still power switching is not working on my raspi with the RSH-A16. Happy to do testing if you have any ideas on how to make it work.

nightyx commented 2 years ago

as an additionall comment.. looking at this discussion: https://github.com/mvp/uhubctl/issues/417 my rsh-a16 has the same (faulty?) chips. However: power switching on the old raspi b+ works flawlessly. Switching with a raspi4b is not working.

mvp commented 2 years ago

I don't quite get what the issue is @nightyx. RSH-A16 works when connected to old RPiB, but not when connected to RPi4B? In that case I would recommend trying to use USB2 only cable to force hub USB2 connection to RPi4B

nightyx commented 2 years ago

thanks for your quick reply

RSH-A16 works when connected to old RPiB, but not when connected to RPi4B?

yes, thats the current issue. And as the old b+ is acting up, I´d like to switch to the 4b :)

Great idea using a usb2 cable. I tried that, and the output is this:

However switching did not seem to work. The output says, that the ports were switched off, but that didnt affect the usb-lights unfortunately. e.g.:

pi@raspberrypi:~ $ uhubctl -l 1-1.1.4.3 -a off

Do i need to turn off the internal usb3 hub stuff on the raspi4b for this? I didnt do that yet, since this should affect the external usbhub, right?

mvp commented 2 years ago

Another idea is to disable xhci. It seems that old hardware would use ehci or uhci, and new would always use xhci (even for USB2 forced connection). I don't remember how to disable xhci exactly, must be either via kernel bootup options or modules.conf setting

TexHexx commented 2 years ago

Hi, do you have Rosonway or RSHTech on the top of the hub? Cause I am having RPi4b also and wanted to order this hub with Rosonway brand on the top.

mvp commented 2 years ago

@TexHexx, I have Rosonway branded RSH-A16 with USB vendor id 0bda, it seems to always work for everything.

nightyx commented 2 years ago

@TexHexx I have the RSHTech-branded version

TexHexx commented 2 years ago

Hi @nightyx, i just got my hub. It is really not working with RPi4b. Mine is branded as Rosonway, but chips are the same "VIA Labs". What RP did you use before on witch it was working?

TexHexx commented 2 years ago

@mvp i think they change chips to VIA everywhere, data is cutting but power is not on RPi4

@TexHexx I have the Raspberry b+, first generation. Unfortunately I don't have access to other raspberries, so I can't test more. Edit: Ah, and if you manage to make it work with the 4b, please let me know

TexHexx commented 2 years ago

@nightyx no way, i took even RPi 3b+ now to test and also not working ...

TexHexx commented 2 years ago

@nightyx @mvp hi guys, tested with RPi3b+ again deeply, working ok, cutting data and power fully on all ports. Will retest now all on RPi4b+ again. Device detected as 2109:2822 Via. On the top of it is Rosonway brend.

nightyx commented 2 years ago

@TexHexx sounds great. What did you do to make it work on the RPi3b+?

TexHexx commented 2 years ago

@nightyx nothing special, reinstall OS again, did update & upgrade and install uhubctl from sources

TexHexx commented 2 years ago

Hello @mvp, after lot of tests i found out that stable work is for ports witch has from 1 to 3 digits bus number, ports with 4 digits not working. So from 1 to 8 ports power switching ok in usb 2.0 mode, in usb 3.0 no port switching at all, but ports from 9 to 16 - can not switch power. Is it possible to do something with it? Can attach any logs if needed.

mvp commented 2 years ago

Sorry, not much can be done from uhubctl side if your hardware is misbehaving. There is very small possibility that uhubctl gets confused with USB2/3 duality and tries to switch off wrong hub pair, but that is only applicable to USB3 mode. If you are unable to control ports in USB2 only mode, that must be hub fault. Since this is USB3 hub, there is a possшbility that its firmware can be updated. However, I do not see Rosonway offering firmware updates. Some companies like Plugable do offer firmware updates for their USB3 hubs, not sure if those can be used instead - most likely not.
