The `usbip list -l' command shows your local usb-devices.
Example:
$ usbip list -l
$ Local USB devices
$ =================
$ - busid 1-1 (13fe:1d00)
$ 1-1:1.0 -> usb-storage
$
$ - busid 1-2 (0409:55aa)
$ 1-2:1.0 -> hub
However this list command doesn't show which device is connected
to this busid. Therefore you have to use another tool e.g. lsusb
to determine that.
This patches adds the possibility to see which device that is.
Example:
$ usbip list -l
$ Local USB devices
$ =================
$ - busid 1-1 (13fe:1d00)
$ Kingston Technology Company Inc. : DataTraveler 2.0 1GB/4GB Flash Drive / Patriot Xporter 4GB Flash
$ 1-1:1.0 -> usb-storage
$
$ - busid 1-2 (0409:55aa)
$ NEC Corp. : Hub (0409:55aa)
$ 1-2:1.0 -> hub
If parsable is specified the info will be not printed.

The command `usbip attach' uses --host for specifing

This is confusing and this patch adapts this.
In Addition changed the manpage and README accordingly.

$ usbip list --remote <host>

Since the names.c/names.h are taken from another project, some
functions which names.c provides aren't used by usbipd.
This patch fixes:
- removed useless comments
- unified debug/error messages by using the macros
provided by usbip_common.h
- removed unnused code
The code cleanup includes:
- remove unused data structures
- remove code to create them
- remove code to access them
The file names.c is used to parse the `usb.ids' file. The parser
stores a lot of information about usb devices that is never used.
The `usb.ids' file has several sections. Some variables (like
`lasthut') store the ID of the current section, and those variables
are used to decide which section is currently being parsed (i.e. in
which data structure the current line will be stored).
We removed the code to read those IDs because they are never used
anyway. We replaced them by the pseudo-ID `1' (instead of reading the
ID from the file) to indicate that the parser is in a section that
can be ignored. If the parser is in such a section, the current line
(which contains sub-items for this section) is discarded.

USBIP daemon relies on functions available in glib2 library
to spawn handler code for incoming connection. This makes the
whole program dependent on glib2 library, which is a GNOME library
that on systems that don't have GNOME results in pulling more
dependency, only to be able to run a relatively trivial
socket-based program.
While this may not seem to be a problem on full-blown desktops
that already have the necessary libraries, it is a big issue
on small embedded systems (think USB hub with an Ethernet port)
that only have bare essentials in their file systems.
This patch eliminates glib2 dependency by reworking the
code to use lower level system calls to dispatch connection
handler. Instead of using glib2-style event loop and dispatching
mechanism, just do a ppoll(2) system call in our own loop and call
accept(2) followed by fork(2) on the socket that has incoming
connection. Stevens' books taught us that more than twenty
years ago. No need for anything smarter in a simple server, such
as usbipd.
