we have applied this article: https://kb.parallels.com/en/124784 Hi Community, We are currently testing Parallels RAS to expand our data center and offer better services. Primarily we currently have the scenario with a customer, webcams which are connected via an IGEL must be usable on the terminal server. The problem is, however, that the RDP connection closes again immediately after logging in if the USB device redirection is active. Without a webcam connected, the Parallels connection to the RDS will not be disconnected. We tested two different webcams (including the Logitech C920). Does anyone have any ideas? No suspicious logs can be seen on the affected RDS server.
