The CPU is more likely than the USB controller. The erroneous pointer values we see are virtual addresses, whereas the USB controller would probably write a physical (or DMA) address if it was malfunctioning. Or it could be some bizarre timing problem with the memory bus, or something else equally obscure. You didn't mention before that this was a SoC rather than an ordinary PC.
