Error Code 19 is raised on USB host controllers when upgrading NoMachine Enterprise Client on Windows from v. 5 to v. 6

This problem has been encountered when upgrading NoMachine Enterprise Client from v. 5.1.26 to v. 6.6.8: after the upgrade, USB forwarding stopped to work in NoMachine sessions and Error Code 19 was raised on USB host controllers in device manager.

This issue is triggered by the fact that NoMachine USB drivers are not updated properly to the new drivers' version provided since v. 6.3.
 

As a possible workaround: 

- uninstall the old NoMachine Enterprise Client, e.g. v. 5.1.26.

- Reboot the Windows machine to completely unistall the old USB drivers.

- Then make a fresh new install of the last version of NoMachine Enterprise Client, e.g. v. 6.6.8 .
