Re: usb keyboard via hub on rpi 3a+

Thank you for all this information, it might take a bit of looking to fully absorb everything that is shown in the descriptors and take note of anything that could be important.

In the meantime I just wanted to clarify a couple of items. Because you have a keyboard that includes a usb 1.1 hub and you are now testing with two different usb 2.0 hubs it is not perfectly clear in some of your descriptions above when you say hub which one you mean so I'll ask you the following:

1. Does the first USB 2.0 hub, the Maxxter device with card reader, work correctly with Ultibo when the USB Keyboard/Hub combo is NOT connected?

2. Does the second USB 2.0 hub, the Vivanco device, work correctly with Ultibo when the USB Keyboard/Hub combo is NOT connected?

3. Do I understand correctly that the USB Keyboard/Hub combo works briefly sometimes when connected to the second USB 2.0 hub and then stops working but never works when connected to the first USB 2.0 hub?

I'm sure you are being very methodical about your tests, I just need to make sure I am following it correctly from afar so we don't waste time with misinterpretations.

The usb hub however does work under linux. Somehow the usb makes the usb part in ultibo freeze when trying to access it?

Regular readers will know that whenever someone says freeze or hang we always want to know more information about the manifestation of that freeze or hang. In most cases a single thread hanging while performing a certain function (like the USB dump to file) will be due to either a deadlock (waiting to acquire a lock that another thread is not releasing) or an exception (such as accessing a null or invalid pointer). In either case it is likely that the rest of the Ultibo core is still happily running and you can use that to assist with diagnosis.

In the case of an unhandled exception then a log entry will often (although not always) be generated to alert that the thread has been halted due to an exception, you can find references on how to enable logging in the Forum Quick Reference.

A thread that is simply waiting to acquire a lock that will never become available can be harder to see but using the WebStatus unit (also found in the Forum Quick Reference) allows looking at the state of each thread and in particular the one you asked to perform the USB dump.

None of the above will provide an instant answer to the problem, they just help to narrow it down further.

In this case it is possible that the keyboard is going into an error state and being disconnected after 5-10 seconds which is why it stops working, any USB error should also be reported in the logging output as described above.

The maxxter does not seem to work ever but i dont have another device to attach to it. With or without the keybard the usb dump 'freezes'

The vivando does not give problems without the keyboard attached. But as with nothing attached i cannot verify its function.

The 2nd hub, the vivando, gives a temporary working keyboard for 5-10 seconds on replugging the keyboard. With the first hub, the maxxter, the keyboard never works.

Dont know how that is going to work in a rpi3a+ without an ethernet adapter. Or is wifi working also? I believe i read wifi is not working yet for the rpi3 series. Maybe next weekend i can try that on my rpi3b+ ( i need to take that out of another project).
