OHCI controller for full speed usb host #41

Closed s-bruce13 closed 1 year ago

s-bruce13 commented 2 years ago

Hello, I'm trying to get the example available running at full speed instead of high-speed. The example is the usbx_host_hid_keyboard for the LPC5528. The keyboard enumerates correctly, but it doesn't respond to any key inputs. The only changes I saw were necessary in board_setup.c/.h which sets up the appropriate USB0, clocks, and interrupts.

I added the ohci drivers in the project. However when calling _ux_host_class_hid_keyboard_key_get, I do not get any information.

Are there any other changes required for full-speed to work?

I'd like to add that these changes are fine, for host_mass_storage example. I can switch between high speed and full speed without a problem.

Thanks for the feedback, we will check that.

There is an issue in the OHCI driver. The fix will be in the next USBX release and also in MCUXpresso SDK.
