When executing a kexec kernel on a PowerPC board the new started kernel will not find already enumerated USB devices due a missing reset on the USB bus. As a work around a echo 1 >/sys/bus/pci/drivers/[ex]hci-pci/BUS-ADDRESS-OF-THE-HCD/reset will solve this. But this is far from beauty. My latest kernel without this issue was for EHCI kernel 2.6.39 and for XHCI kernel 3.4, but i have no idea when exactly this behavior was introduced. For X86 all is fine. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
