Hi,
It appears your USB Host Controller Hardware has crashed.
Could you boot having the following line in /boot/loader.conf:
hw.usb2.uhci.debug=15
And send new dmesg.
Patch you can try in the meanwhile:
Edit /sys/dev/usb/controller/usb_controller.c:
- usb2_dma_tag_setup(bus->dma_parent_tag, bus->dma_tags,
- dmat, &bus->bus_mtx, NULL, 32, USB_BUS_DMA_TAG_MAX);
+ usb2_dma_tag_setup(bus->dma_parent_tag, bus->dma_tags,
+ dmat, &bus->bus_mtx, NULL, 30, USB_BUS_DMA_TAG_MAX);
This will reduce the DMA bits to 30.
--HPS
