I have UoN Server running at my laptop with Win7 (Core i3 2.2GHz, 3Gb RAM) and UoN Client at my PC at work (WinXP SP2, Celeron 2.6GHz, 1.5Gb RAM). Laptop and PC are connected via VPN, so I can open connection from laptop to PC (and I suppose, from PC to laptop too).
When I plug the USB flash drive to a laptop I can see it in the UoN Server window and click "Share USB Device". At work in UoN Client I can also see my USB flash drive and click "Connect USB Device".
But when I press "Connect USB Device" button in UoN Client, explorer on PC just hangs - I can not update information (via pressing F5) about connected disks in "My Computer", but I see the drive in the "Safely Remove Hardware" and I can extract it. When I press "Disconnect USB Device" button in UoN Client the flash drive appears in "My Computer" for a second and then disappears. After that explorer at PC droops and everything going OK.
This is a known issue and our developers are working on finding ways to fix it. It may happen that your explorer can stop hanging in 5-10 minutes. It happens with some USB devices that send a lot of information to the system. And when this information is being redirected through the network it causes hanging. We will let you know when this issue is fixed. If you want to help us in resolving this issue please write us to support@fabulatech.com so we can continue our conversation by e-mail
