I am having similar issues.  Writing to an SDCard sometimes kills all
USB ports.  I can recover all USB ports by logging in over ssh and
running the following script:

for port in $(lspci | grep USB | cut -d' ' -f1); do
    echo -n "0000:${port}"| sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind;
    sleep 5;
    echo -n "0000:${port}" | sudo tee /sys/bus/pci/drivers/xhci_hcd/bind;
    sleep 5;
done

This has happened 3 or 4 times in the last 2 weeks and each time I can
recover without reboot.
