3.3 NEO Expansion Port USB Host Interface

The USB host interface is automatically enabled by the DTS (Docking and Tether Port Ser-

vice) when the expansion device is detected. DTS can be configured to not enable the USB

host interface through the following registry value:

Registry Key: [HKEY_LOCAL_MACHINE\Services\TekDTSvc\ExpansionPort\1\]

Registry Value: “ConfigTether”=dword

The value of ConfigTether should be set to one of the following values:

3.4 NEO Windows-Resident USB Drivers

NEO comes in two classes of hardware configuration: connected and unconnected (or

“batch”). Connected versions of the NEO run Windows CE 5.0 Pro as the operating system,

while the unconnected versions run Windows CE 5.0 Core. Both operating systems include

drivers for operating USB devices through the USB interfaces on the device.

The docking interface on the base of the NEO has pins dedicated to USB communication,

and can be used as either a USB host or USB device, via a partial USB On-the-Go interface

(USB OTG). However, the USB interface pins on the expansion port can be used only as a

USB host connection.

Without adding new drivers, both external USB host ports can be used to support external

keyboards, bar code scanners, the Psion Teklogix USB-to-Serial adaptor, the Psion Teklogix

USB-to-Ethernet adaptor, and USB memory keys. There is no support for a USB mouse,

modem or printer.
