FortiClient x in Windows 10 and HSM devices

[mirko1]

We are experiencing a weird behaviour with FortiClient 5.6.6.1167 on Windows 10.

We use USB-connected HSM devices (https://github.com/inversepath/usbarmory/wiki/Host-communication#setup--connection-sharing-windows-7...), which are normally detected as "USB Ethernet/RNDIS Gadget".

Unfortunately, when FortiClient 5.6.6.1167 is installed, only on Windows 10, such devices are detected as "Fortinet Virtual Ethernet Adapter (NDIS 6.30)". As a result, the device never connects, despite the fact that Windows 10 sees it as correctly configured.

The HSM device works perfectly on Windows 7 + FortiClient 5.6.6.1167.

In Windows 7 the driver details show `C:\Windows\System32\drivers\usb8023.sys`.

In Windows 10 the driver details show `C:\Windows\system32\drivers\ftvnic.sys`.

Thanks.
