SUMMARY = "userspace usbip from Linux kernel tools"
DESCRIPTION = " USB/IP protocol allows to pass USB device from server to \
client over the network. Server is a machine which provides (shares) a \
USB device. Client is a machine which uses USB device provided by server \
over the network. The USB device may be either physical device connected \
to a server or software entity created on a server using USB gadget subsystem."
