Approved Sewell USB Drivers

Please Note:  The Sewell USB-to-Serial adapter was standard on CompuTrainer for about 4 years and is recognized by the blue housing marked with the words SEWELL.  It, as well as a previous adapter (created by BAFO, which was black and had a removable cable) used a program chip manufactured by Prolific.  The drivers shown below may NOT be the latest drivers Sewell/Prolific has released for use for these operating systems, but they are the drivers we have found to be the most stable when used with CompuTrainer.

If you have a Vista 64-bit computer or Windows™ 7 (any version), we recommend upgrading to the current FTDI-based adapters as no drivers have been found we feel work. 

Please note as well that if you have Vista 32-bit and use the Sewell adapter, and have the operating system set to automatic updates, the operating system may update drivers without you knowing -- thus replacing the working drivers with "newer" non-working drivers; in which case you must reinstall the older drivers again, by force.

Unzip the files into a Sewell folder you create and using the driver update wizard in Device Manager, point the driver update to the location where these file reside.

Windows™ XP (zip file)

Windows™ Vista (zip file) (64-bit Vista and Win7 users should NOT use the Sewell/Prolific adapter)

FTDI-based adapter

Approved FTDI-based USB Drivers

Please Note:  An FTDI-based adapter has been standard with CompuTrainer for all Vista 64-bit sales beginning October 2008 and then became standard on all CompuTrainers sales beginning in December 2008, at which point all in-house support for the Sewell adapter was suspended - except as noted above.  The first FTDI USB-to-Serial adapter is recognized by the tan and blue housing with blue lights flashing when in use.  This driver is the same for all FTDI adapters including our new custom FTDI-based USB-to-Stereo adapter, which now ships with all new CompuTrainers as of January 2009.

This driver executable is the same for all operating systems and will correctly detect and install the driver for the operating system you have.
