I just verified the USB hub fixes from felis/USB_Host_Shield_2.0#414 work on the USB Host Shield. I will see why they do not work on SAMD.
from usb_host_library_samd.
_EDIT: Never mind. I don't know what's going on, but today, the original lib (gdsports) works fine, although enumeration is slow. _
I had this issue also. The in particular, the example in USBH_MIDI/USB_MIDI_converter_multi only worked for me if I had a single controller on the hub. I used @DatanoiseTV's fork, and everything works ok reading midi from two controllers. For a project I'm working on (not yet in github) I need to be able to write the devices as well. Here things did not go so well, even with @DatanoiseTV's changes, until I refactored the example code to wait in setup() for the devices to be ready before going into reads/writes in loop(). Even so, it takes about 45 seconds for my devices (Source Audio guitar effects pedals) to be ready to go into the read/write loop, which seems excessive. I forked your repo, and then merged in @DatanoiseTV's changes, so my fork is current with your repo. Let me know if you want me to do a pull request. BTW, Thanks for doing this port of @felis's UHS2! My goal was to be able to debug/test an Arduino Uno using UHS2, and deploy with your SAMD port on my Trinket M0, and that looks like it's going to work out at this point.
