... The card was recognized by the Windows PC and the driver is installed automatically, but the application could not open the ports to communicate with the devices. When replacing the driver (from the CD), there was a system crash (blue screen), which unfortunately came back every time you restart. It helped only to reset the system to an old restore point and work the drivers automatically found. Unfortunately we had no success with the device communication (in our case a serial receipt printer and cash register display) and the product can not be used. :-(
