If you had got your Stylus R240 unit without any ST1000BT64 driver CD or the latter is lost, you may choose to follow the links below. Without a special Stylus R240 driver to your unit, you won’t be able to use all its StarTech.com functionality. The basic ST1000BT64 driver from Windows is only able to support the minimum OmniAccess AP65 set thereof. You are really in need of a fully-featured authentic ST1000BT64 driver.
For Stylus R240 download, please just follow the ESPRIMO V6535 link.
