iLok Error Across Windows Clients with Server Running on Ubuntu 22.04

Submitted by asai on #1

Greetings,

Thanks Michael for all the work you've done on this great piece of software.

I have VirtualHere generic server running on an Ubuntu 22.04 desktop (installed today via script) and 2 Windows 10 clients.  uhubctl for Ubuntu is installed and I've been successful at power cycling the iLok port via CLI.  And to be sure, I've added the onUnbind.088e.5036=uhubctl -l 2-1 -p 6 -a 2 (corresponding to the correct hub and port.) I'm attempting to share an iLok across both computers (not simultaneously,) but when I disconnect from one computer and try to connect on the other I get the "Cannot be shared across multiple operating systems" error.  

This is what I'm getting in the syslog when I disconnect the iLok from the vhusb client:

Apr 29 11:02:59 serverrm vhusbdx86_64[376093]: Executed "uhubctl -l 2-1 -p 6 -a 2" for onUnbind.088e.5036

Apr 29 11:03:01 serverrm vhusbdx86_64[376093]: Device 216 [088e:5036] BOUND to connection 2

Can you point me in the right direction on troubleshooting this?

I should add that I get the error only on one Win 10 computer.  

On the first, the Ilok comes up normally, but on the second I always get the sharing error.  I've shut off Virtual Here client on PC #1, restarted both server and PC #2, and I still get the sharing error on PC #2.

This is expected behavior, you must use a per-port-power switching hub.

VirtualHere will be selling USB Hubs with Per-Port-Power-Switching in the next month or so.

However in the mean time you could buy one from this list, https://github.com/mvp/uhubctl 

The best of the list would be the MEGA4 but it has an awkward USB connection to the host and you need a usb female to male cable which is not easily purchasable since its non standard.
