Hi, I realize there is an issue with PCI devices due to the possibilities of a bad DMA due to a bad driver/device. Does this problem manifest to USB drivers as well or does the usb core ensure that the DMA addresses are always mapped correctly? Can anyone point me to the code file where this is being done.
