MSP432E401Y: ULPI Interrupt not working

Part Number: MSP432E401Y

Hi,

We are interfacing MSP432E401Y (Development kit) with USB3300 (Waveshare module) in host mode.

To start off, we tried USB Host Mouse example in FS mode.

But there is no interrupt when the mouse is connected or disconnected and hence not getting detected.

Changes made to the example:

1. External USB clock enabled (USBPLL disabled)

3. ULPI command sent to USB3300 to turn ON power by enabling CPEN pin
