USB Driver Installation

The 

Actisense

 USG-1 makes use of a virtual serial port 

driver (know as the Virtual COM Port Driver) to interface 

between  the  USB  port  on  the  PC  and  the 

Actisense

 

product.  This  driver  allows  software  running  on  a  PC 

to  communicate  with  the 

Actisense

  USG-1  as  if  it  was 

connected  to  a  standard  serial  port  on  the  PC,  when  in 

fact all communication is done over the USB connection.

The  required  driver  installation  comes  in  two  separate 

packages. The first driver is a called the ‘Serial Converter’ 

which  converts  the  USB  data  packets  to  a  serial  data 

stream.  The  second  driver,  called  the  ‘Actisense  USB 

Serial Port’, makes the USB connection appear as a COM 

port in the Windows Device Manager. 

The  USG-1  with  USB  connection  has  been  extensively 

tested with both Windows XP and Windows 98 SE.

For  the  experienced  Windows  XP  user  who  is  used  to 

installing  drivers,  this  section  will  be  very  familiar. To  all 

other  Windows  users,  the  required  steps  are  detailed 

below to help with installation.

The steps for Windows 98 SE are very similar to those of 

Windows XP and so are not detailed here.

The 

Actisense

  CD  also  contains  the  USB  drivers  for 

Windows  2000.  These  drivers  have  not  been  tested  by 

Actisense

, but should operate in the same manner as the 

Windows 98 SE and XP drivers.

The  required  Linux  drivers  are  already  included  in  the 

Linux  kernels  from  v2.4.20  and  onwards.  However, 

Actisense

 has not been able to test the compatibility of 

the USG-1 with USB and this driver. 

For  MAC  OS  8,  9,  and  X  please  contact 

Actisense

  for 

details (refer to the 

Company Information

 section).

Step by step guide

1.

  Make  sure  the 

Actisense

  USG-1  is  connected  to  an 

available  USB  port  on  the  PC.  The  standard  Windows 

‘Found New Hardware Wizard’ window will then appear.

Select  the  ‘

No,  not  this  time

’  option,  to  allow  driver 

installation  from  the 

Actisense

  CD  which  was  supplied 

with your Actisense product.

2.

  Insert  the 

Actisense

  CD,  choose  the  ‘

Install  from  a 

list or specific location

’ option, and click ‘

Next

’.
