Hello. I am implementing USB Host functionality on the LPC4088 for pendrive support. The code works correctly on the LPC QuickStart board, but fails to enumerate devices on our custom hardware.
Specifically, `USB_Host_SendControlRequest()` returns `HOST_SENDCONTROL_PipeError` instead of `HOST_SENDCONTROL_Successful` during enumeration. I suspect the issue lies within `HcdControlTransfer()`, possibly related to pipe configuration, but I have been unable to identify the root cause.
Any insights would be greatly appreciated.
