This is the driver for the Entrega hub4U2S1P. Under Windows 2000, the drivers worked great. I did have some problems with the serial port emulation. When I installed the serial port portion of the driver, I had to check the "Install one of the other drivers" and select the Xircom driver. The default selected drivers did not work properly in my case. The ZIP file includes a readme with complete instructions.
Although it is tough get running, but I've enjoyed it so far. ) Good luck!
