3. Check Driver Installation.
------------------------------

    a. Open the Windows Device Manager
	i) Right-Click the "My Computer" icon on the Desktop.
	ii) Select "Properties" from the drop-down menu.
	iii) Click the "Hardware" tab.
	iv) Click the "Device Manager" button to show the current Hardware list.

    b. Confirm that the New Hardware has been included
	i) ASIX USB Compound Device is in the Universal Serial Bus Controllers. 
	ii) "USB SerialPort (COMn)"  in Ports (LPT & COM) categery 
	ii) "USB ParallelPort (LPTn)"  in  Ports (LPT & COM) categery 
	iii) In our case, one  Serial Port and one Parallel Ports were added.


4. Removing Previously Installed Drivers
-----------------------------------------

Sometimes it will be desirable or even necessary to remove the previously installed 
drivers, so that a new, clean installation can be performed. Drivers can get 
corrupted when being written to their installation medium (CD-ROM etc.). If this 
happens, the drivers may not install properly.Even if the installation proceeds 
without errors, the drivers may not work. Sometimes older outdated drivers are 
shipped with a product. Newer machines may require newer updated drivers, but the 
older drivers prevent them from being installed. The easiest way to remove old 
drivers is to use the MosUPortUninst.EXE program (located in WINNT\System32 
directory or in the Installation disk supplied with the product). 


Using MosUPortUninst.EXE to remove old Drivers

    a. Unplug the USB Compound device. 

    b. Open Start->Settings->ControlPanel->Add/Remove Programs.

    c. Select "ASIX USB Compound Device" click change/remove. 	    

    d. At the next dialog, Click "OK" button. 

    e. Then click "RebootNow" button to reboot the system.
