Hello,
I have setup a linux client with ftusbrdpd and freerdp plugin
I got from ftusbrdpd the debug information:
D: 1488897400: conf_update_mode: Section [all] has got rule weight = 1
USB for Remote Desktop version: 5.2.3
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.

if I started the process with "strace ftusbrdpd -v debug" I got:
...

) = 47..
which means, it tries to open library cache to find libudev.so.1 and does not find it.
But ldconfig -p shows the libray:
...
libusb-1.0.so.0 (libc6) => /lib/libusb-1.0.so.0
libupower-glib.so.1 (libc6) => /lib/libupower-glib.so.1
libupower-glib.so (libc6) => /lib/libupower-glib.so
libudev.so.1 (libc6) => /lib/libudev.so.1
libthunarx-2.so.0 (libc6) => /lib/libthunarx-2.so.0
libtheoraenc.so.1 (libc6) => /lib/libtheoraenc.so.1
libtheoradec.so.1 (libc6) => /lib/libtheoradec.so.1
libtdb.so.1 (libc6) => /lib/libtdb.so.1
...
any Ideas?
