I had to put on the search for a solution to a USB port in a virtual machine (HyperV / Vistax64) available. I have some software solutions tested: While you run, but unfortunately Reboots led very often to errors (device was not connected to reboot) .Because I want to here about unattended data from a weather station (IROX Pro) read matters in both absolute reliability , I then pushed research on the Silex SX 3000GB and have this installed at me. Since then I have not a single mistake more. At the Silex I first connected a weather station (this is in the virtual machine read by WSWin), then wanted to know what else goes like this: WebCam, hard drive - no problem, I then HD2 my on the charging station to the Silex connected and via WLAN connected to a laptop: works perfectly! If you put the HD2 in the charging station it automatically connects to the laptop, ActiveSync will start immediately with the device synchronization. Now my HD2 infected at home mostly in the charging station while I was using the laptop to move freely in the home and can use the HD2 via remote software if necessary / control. Again: - previously a single mistake Always in the charging station / out of the charging station, reboot the laptop. I have the Silex since about 8 weeks in operation, the client software runs with me on WinXP, Vista x64, Server 2008R2, Win7x64 without any problems so I'm still to procure additional equipment.
