Copy the SIUSBXP.DLL and SIUSBXP.REG files the the \Windows directory on the CE device. 2. Plug in the CP210x Device with VID 10C4 and PID EA61. If your cP210x still contains the default VID and PID (10C4, EA60) use the CP210xSetIDs.exe application in located in Application Note to change the PID to EA61. AN144 and its software package (AN144SW) are available here: http://www.silabs.com/tgwWebApp/public/web_content/products/Microcontrollers/en/mcu_applications_appnotes.htm 3. When the dialog pops up saying "Unidentified USB Device" enter SIUSBXP for the driver name. The dialog should close when OK is pressed, and the LED on the CP210x development board should be lit. (If the dialog doesn't pop up, but the LED on the CP210x development board is on, then it automatically found the device) 4. The two included test applications can now be run (CP210xWinCETest.exe and CP210xWinCEtoWindowsHTTest.exe) using the CP210x in loopback mode. To put the device in a loopback state, disconnect the two jumpers for TXD and RXD, and reconnect one jumper joining the TXD and RXD pins closest to the USB port - see Figure 1. Under Normal Operation, running CP210xWinCEtoWindowsHTTest.exe will write to HyperTerminal when hooked up via a Null Modem Cable.
