Title: USB over Network 4.7 on Linux problem
Post by denis.sizikov on Sep 20th, 2011, 11:20pm
Trying to use USB over Network 4.7 on Linux (Oracle Unbreakable 5.5, kernel 2.6.18).

While starting ftusbnetd in debug mode error displayed:
# ftusbnetd -d
Usb Over Network (for Linux) version: 4.7.0 (compatible with 4.7.0 or newer)

This software uses the libusb 1.0 library.

Public License and the GNU LGPL. You can obtain updated versions
of libusb and the source code from the libusb homepage at
http://libusb.sourceforge.net.

License key '/etc/ftusbnet.key' not found.

Trial: 15 day(s) left
Up to 2 devices supported

D: 1316585852: ftusbnet_run: using libudev for hotplug notifications
libudev: udev_monitor_new_from_netlink: error getting socket: Invalid argument
E: 1316585852: udev_open: udev_monitor_new_from_netlink() failed

Truing to list or share USB devices just hangs with output
ftusbnetctl list
 Id     VID: PID: REV    Location  Device name and status


Any suggestions?

Hello Denis,

Could you please answer a couple of questions:

1. When you plug the device in do the logs react? Do you have any information in your logs when you plug/unplug the device?

2. Does it happen to all the devices (keyboard and mouse too)?

Initially, only Keyboard and Mouse are connected (both are USB)

When I use ftusbnetctl list command, it hangs after displaying header (see 1st post) and does not return shell prompt.

Daemon, started with debug option (ftusbnetd -d )in other window does not produce any output during any device connection/disconnection
