Thanks for the report! Good catch, I might know what the issue is, could you please test this firmware for me and report back?
It's almost working :)
It correctly identified both keyboard and mouse connected through the HUB and worked perfectly. However, once I disconnected the HUB's cable and connected again, nothing was detected until Raspberry's restart
And this behavior is consistent: first connection after RPi restart - everything works; any subsequent re-connections - no
This seems like a TinyUSB issue, deadlocking when two devices try to enumerate in a very short timespan (or something similar). I've tried to dogscience it, but I don't know what I'm doing so it might blow up.
Any improvement with this? beta_firmware2.zip
hmmm... After changing to the beta2 firmware it completely stopped recognizing mouse via the HUB. But after rolling back to the beta1 firmware I wasn't able to reproduce the behavior even from my previous comment... I'll try to do more experiments tomorrow
I have managed to recreate it, seems like it fails with:
[1:] [1:] USBH Defer Attach until current enumeration complete
and ends up in a deadlock. First 1 or 2 re-plugs work for me, then it hangs. With just one device plugged in the hub it works as well... This looks internal to TinyUSB, more debugging needed.
First of all, thank you very much for this project! The idea, documentation and the quality of models/schemas are amazing! It was a pleasure to build this device, everything went smooth
The update from yesterday indeed enabled partial support of USB HUBs. However, there's an issue I'm facing with mine:
I use Ugreen USB switcher (https://www.amazon.co.uk/dp/B01N6GD9JO?ref_=cm_sw_r_cp_ud_dp_8NEX4KNSA6PH3T8T8QWG), I've connected my keyboard and mouse into 2 USB ports (2 other ports are empty). However, only one device is recognized by Deskhop.
When I switch outputs on Ugreen, or if I simply unplug and plug it in - only keyboard is recognized and works. The mouse is not detected.
In case I try to unplug the devices from the HUB and plug one by one - only the first device is recognized. For example, if I plug the mouse first and then the keyboard, only the mouse will work. It doesn't depend if the USB HUB is connected to A or B.
Is there any other debug info I can collect (I use Linux on both computers, in theory a Windows one is available)
