linux client error

I'm getting an error I don't understand -- when I do the ctl tool with a list, it doesn't show the devices being shared on the server:

Hi
According to the /opt/ftvusbnet/doc/README first of all you must compile and load the kernel module fthc.ko:
   cd /opt/ftvusbnet/module
   # tar -zxf fthc-module.tar.gz
   # cd fthc
   # make
# insmod fthc.ko
You can run the ftvusbnetd daemon after that.

Thanks for the reply.
 
But I have already done the steps in the README and it doesn't shows any issues while executing those steps.
 
But couldn't list the devices.

Hi !
Please send me (to support@fabulatech.com) the following:
- the output of the "uname -a" command;
- the screenshot of the execution of these three commands:
 make //from the /module/fthc folder
 insmod fthc.ko //from the /module/fthc folder
 ftvusbnetd 10.2.21.xxx:33000 -v debug //from the /opt/ftvusbnet/sbin folder
Thanks in advance.

Hi I encountered this as well, it looks like in the actual client script (bin/ftvusbnetctl) they specify the port as 1024. It looks like yours is running on 33000, by opening that script in a text editor and changing all the values from 1024 to 33000 you should be able to get a list of devices.
