Automatic USB mounting #322

Hi!
I'm working on a simple project where I only need to keep a "flashy" gaming mouse and keyboard awake, so they can do their flashy things. When the mouse or keyboard is connected to a USB charger, they don't power up, so it seems they need initialization.
I'm thinking about using a Raspberry Pi Pico as a USB host for this.

I've been able to get this working using a generic USB hub together with the device_info sketch. However, when unplugging and re-inserting the USB connector, the USB hub (or any other device for that matter) doesn't get mounted, and I'll have to physically reset the Pico in order for the mouse and keyboard to "flash" again.

Is there a way to automatically mount a connected USB device without having to reset the Pico?

Thanks!

it should auto unmount, and remount device. Try to enable debug log to see what went wrong.

Thank you for your reply @hathach! Sorry, but I'm new to both the RP2040 and the TinyUSB library. I tried to enable debugging in the TinyUSB library by defining CFG_TUSB_DEBUG as 1 or 2. If I define it as 3, I'm getting a "USB not recognized" error from Windows.

However, when I have CFG_TUSB_DEBUG defined, I'm not getting any other output than what the test sketch provides.
Are there any additional steps I should do to properly enable debugging?

For reference, I'm using the earlephilhower rp2040 core.

log is output via UART (Serial1)

Now I can't get it to initialize any usb device. Not sure why. I've chopped off a male-to-female USB A connector and soldered it to VBUS, GND, GPIO16 (D+) and GPIO17 (D-).

When I apply power to the target, the USB device (a keyboard) is already connected. I then unplug it, and connects it again.
