RTOS/TM4C1294NCZAD: USB hangs when using SSI2

Part Number: TM4C1294NCZAD

Tool/software: TI-RTOS

Hello

We are building a test application, that send commands through the USB, and gets a response after performing some HW calls.

We see a USB freeze after any call to the SSI2 interface (connected on port G Pins 4,5,6,7).

Even when calling the SSI2 from the SW without using the USB - the USB is being disconnected.

We are able to use this interface without USB.

We are able to send requests and get responses on SSI3 (flash - read and write byte streams) using the USB.

any ideas?
