[question] Kobo nia USB OTG as a host

[Szybet]

First, I want to thank that this repository exists, I really appreciate that, It made kobo better than other ereaders on the market

So here is my question, is it possible to use the kobo nia as a usb host? just like it was made here. I tryied the same thing, but with no success.

Here are the dmesg logs

They are cutted out and connected together for the most important part, but the point is it registers new usb devices, begins with 0 and goes infinite. I also measured the power consumption of the keyboard, it was raising to 50 mA and then back to 2 mA ( i was using an external power supply, yes the ground was connected together ) all the time. Also, there were only those logs with only one keyboard, using the oryginal or a other OTG cable.

Any ideas? I tryied recompiling the kernel, adding drivers, nothing worked.
