USB Device Server SX 3000 GB

We use the device server for a printer in the private network. Since we have a multifunction printer that Fritz was not ideal, because the scan to the printer does not work directly on each PC. For the SX 3000GB is the right person. If you want to print, the server automatically connects the printer to the PC during and after printing, the printer automatically unlocks. When scanning of the printer (scanner) is manually connected to the desired PC (click) and after scanning the printer must also be released again so that it is again available for other network users.
We have two Windows7 - installed PC (a 64-bit, 32-bit) software. On the 32-bit machine within 5 minutes, the 64-bit machine was a little more complicated, but then worked.
The server runs without problems for 2 weeks.
