USB can not generate interrupt upon DMA read/Write Access error

Details:

USB does not have mechanism to generate error event / interrupt if its DMA R/W access sees read/write error response on VBUSM. This can happen if there is address/MPU error while accessing the memory, resulting in bus hang.

Workaround(s):

  1. SW needs to program correct addresses for TRB’s and Data.
  2. Use USB transfer time out and read following registers which log the bus error

GSTS. BUSERRADDRVLD (Host/Device Mode)
USBSTS.HSE (Host Mode)
