Microsoft driver. Instructions for making the replacement are included in "To Update the
OrangeUSB USB 2.0 Driver".
To Update the OrangeUSB USB 2.0 Driver:
This procedure is highly recommended when a laptop computer will be used to
communicate with the ST-133. As stated before, we recommend the SIIG, Inc. USB 2.0
PC Card, Model US2246 if USB 2.0 is not native to the laptop's motherboard. To reduce
the instances of data overruns and serial violations, the OrangeUSB USB 2.0 Host
Controller installed for the SIIG card, should be replaced by the appropriate Microsoft
driver (Windows XP or Windows Vista, depending on the laptop's operating system.)
Note: This procedure may also be performed for desktop computers that use the
Orange Micro 70USB90011 USB2.0 PCI.
