Example code doesn't seem to work with Pico-PIO-USB 0.7.x

[HanYangZhao]

Describe the bug
I ran the example code with both Pico-PIO-USB 0.6.1 and Pico-PIO-USB 0.7.0 with the following outputs. The only change i made was
#define PIN_USB_HOST_DP 12. I'm not using a hub. Could it be related to sekigon-gonnoc/Pico-PIO-USB#149?

Pico-PIO-USB 0.6.1

Pico-PIO-USB 0.7.x

I tried unplugging and re-plugging my midi controller but no change, it doesn't seems to get detected

Expected behavior
Same outputs for both versions

What is your setup like?

• RP2040
• usb_midi_host master branch
• arduino-pico @ 4.4.0

@HanYangZhao Your change should not matter. Do you use a USB hub? If you are not using a hub, then I do not know the answer. If you do, then I would say it is possibly is related to the the same issue. Either way, this issue needs research in the Pico-PIO-USB project or perhaps the adafruit_tinyusb_arduino project.

@HanYangZhao What version of Adafruit TinyUSB library are you using?

[HanYangZhao]

I was using the bundled Adafruit TinyUSB version from arduino-pico @ 4.4.0. From the commit , I think it's 3.4.1
