Virtualhere for steam link (please purchase a licence to share more devices simultaneously

Hi ,
I'm from Turkey
I purchased VirtualHere for Steam Link (unlimited) on steam.
i am using on raspberry pi. when i plug in a second or third device (mouse, joystick)
this warning pops up
"please purchase a licence to share more devices simultaneously"
(i think trial version installed)
I would be glad if you help.

0. Stop and exit the virtualhere client if its running on your pc
1. In the pi steamlink menu select the virtualhere section and select the USB devices you want to use via virtualhere
2. Click Start Streaming and then everything is automatic. You dont need to use any devices yourself in the virtualhere client, and you dont even need to start or download the virtualhere client yourself.
