USB vs. other interrupts

how working interrupts on the LPC11u67, when is active USB HID_GetReport()? It is possible temporary disable the HID_GetReport() request?

Main loop communicate with memory by SSP0. SSP0 is working in the interrupt mode. Through USB HID Report Feature I need sometimes read the memory, but when is activate HID_GetReport(), the SSP0 stopping work. The HID_GetReport() is look as a interrupt with highest priority than SSP0. The SSP0 do not transfer all bytes, but HID_GetReport() is waiting for it, code is on loop.

Can I temporary disabled USB, when SSP transfer is provided from main loop, or setting "interrupt" priority?

The USB and SSP are based on LPCOpen library.

Thank You
