Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of Devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure Devices at startup or when they are plugged in at run time. These Devices are broken into various Device classes. Each Device class defines the common behavior and protocols for Devices that serve similar functions. Some examples of USB Device classes are shown in the following table

CrE-ME410_X86_CE40_HPC The .exe file that you will receive upon download is an installer to be executed on a Desktop PC to which your Windows CE Device is attached through ActiveSync. Should this fail (and also if it succeeds) you can find a CrE-ME CAB file in the ActiveSync folder on the PC ("\Program Files\Microsoft ActiveSync\NSIcom") which you put on the Device to install CrE-ME (by clicking on it as it appears on the Device s file explorer).

DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new Devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, Device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.
