Dear all,
This series of patches introduces WebSocket to USB/IP.
0. Version info
V2)
# Formatted patches from linux-next.
# Fixed change log word wrapping.
# Removed SSL patches.
# Fixed a bug that vendor and product names are not shown by usbws list
-l because usbip_names_init() was not called in libusbip.la.
1. Why WebSocket?
It allows to use USB/IP in internet. WebSocket is widely used to
encapsulate packets in HTTP and to carry them through firewall using
HTTP port numbers.
Assumed use case is a system that service in internet serves
distributes devices in home or office networks. Service may be called
as cloud and devices as ubiquitous.

Device Service

cameras ................................... monitoring, recording
ID/biometric readers ...................... authentication
2. Features included
It also includes some independent features effective in themselves.
1) Exporting devices
Export request and response PDU had been defined in a header but not
been used.
Now it works!
Also, it supports senarios, for example, connect ubiquetous devices to
a Linux based cloud service.
In this senario, it's needed to establish connection from a device
inside of firewall to a service outside. Exporting is suit for the
senario.
2) User space transmission
USB/IP transfer URBs in kernel space. It's better for performance but
difficult to introduce application protocols.
Like fuse for file systems, it allows to transfer URBs in user space.
When usbip_ux.ko is loaded, it replaces kernel_sendmsg() and
kernel_recvmsg() with user spcace interface. When USB/IP utilities find
usbip_ux.ko, they start threads to read/write PDUs from/to usbip_ux.ko
and send/recv them.
3) Replaceable protocols
Both transmission(send/receive) and connection establishment are
replaceable.
4) a WebSocket implementation
It's made with Poco C++. DNS and proxy are supported.
I published scripts I used while developed the patches.
