hi wila,

thank you... that was the problem.

In SUSE tumbleweed the vmware service doesn't start at boot, I don't know why but also using YAST I can't do that.

Anyway, everytime I need the workstation I run manually 

sudo systemctl start vmware.service

 and it works.

Now I updated the script:

sudo systemctl start vmware.service
sudo vmware-usbarbitrator

 and now I can see the usb devices in removable devices.

Also note that I can see the mouse and keyboards devices only in the VMs where I modified the vmx like in the KB guides.

I think that the services problem have to do with the kernel... I'm running 5.10.16-1-default by now, while in the OpenSUSE 15.2 I have not services problem and it is running the 5.3.18-lp152.63-default kernel.

I hope this informations will be of any help to someone else.

Manually run a script every time i boot is not ideal, but it works.

Thank you for your help.
