            I also have this problem.   I've used the trial version 4.7.2 on Linux successfully, but after installing license key into /etc/ftusbnet.key, I get the following error message      # /opt/ftusbnet/sbin/ftusbnetd -d -k /etc/ftusbnet.key   Usb Over Network (for Linux) version: 4.7.2 (compatible with 4.7.0 or newer)      This software uses the libusb 1.0 library.   The components of libusb are distributed under the GNU General   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.      Trial error: -4      The operating system is XenServer 5.6 (which is based on CentOS 5.x)
