Small learning Mono/C# project to use client/server technology (based on ZeroMQ) to monitor USB events on Linux and send them to Windows WPF client
To start working on Linux side you need to follow those steps (original article here: http://www.kernel.org/doc/Documentation/usb/usbmon.txt)
Mount debugfs (it has to be enabled in your kernel configuration), and load the usbmon module (if built as module). The second step is skipped if usbmon is built into the kernel.
# mount -t debugfs none_debugs /sys/kernel/debug
# modprobe usbmon
Verify that bus sockets are present.
# ls /sys/kernel/debug/usb/usbmon

On my Ubuntu [Ubuntu 12.04.1 LTS] there new devices come up /dev/usbmonX X means bus number. In this project I user usb device connected to bus 1.
The architecture is simple:
- Make P/Invoke call to Ioctl(...) to receive numbers of USB events waiting in queue and collect them
- Raw events converted to UsbMonPacket and serialized to XML
- XML object serialized to byte  array and send via ZeroMQ socket to Win32 port 5555
- Win32 (server) listening (via Replay socket) on port 5555 and basically to reverse to above steps (de-serialize to XML and then to actuall UsbMonPacket)
- When UsbMonPacket finally constructed then new event rised and collected by .GUI project
- Then it should be finally presented on screen and user notify about it
P.S. As for now [07-November-2012] there's a lot of TODOs and event broken/bugged classes. I'm working on them on my spare time so it will be fixed slowly but general idea should work. Enjoy !
