	- List driver assignments for USB devices.



    server:# usbip bind --busid 1-2

	- Bind usbip-host.ko to the device with busid 1-2.

	- The USB device 1-2 is now exportable to other hosts!

	- Use `usbip unbind --busid 1-2' to stop exporting the device.

usb-storage driver. To export this device, we first mark the device as

"exportable"; the device is bound to usbip driver. Please remember you can not

[Checklist]

    - See 'Debug Tips' on the project wiki.

	- http://usbip.wiki.sourceforge.net/how-to-debug-usbip

    - usbip-host.ko must be bound to the target device.

	- See /proc/bus/usb/devices and find "Driver=..." lines of the device.

    - Shutdown firewall.

	- usbip now uses TCP port 3240.

    - Disable SELinux.

    - If possible, compile your kernel with CONFIG_USB_DEBUG flag and try

      again.

    - Check your kernel and daemon messages.

        ex. /var/log/{messages, kern.log, daemon.log, syslog}

    - If possible, compile your kernel with CONFIG_USB_DEBUG flag and try again.

    - Check the kernel and daemon messages.
