Re: USB Serial Driver

IIRC Atmel typically implement the function side of USB CDC Modem
Class (uses "usbser.sys" driver in XP). CE5 do not ship with any sort
of USB Serial/Modem Host class driver, so unfortionately you have to
write the driver yourself. There might exist 3:rd party drivers for
CE, but I don't know any.

Thanks a lot for your response.

Basically my Black box works like a RS232 to USB and USB to RS232 device.
For this we are using ATMEL 89C5131 8 Bit uController PCB. In addition to
simple RS232 to USB functinality it will do lot of other analog sensing
process. ATMEL given there Vendor ID and Product IDs.

If I connect this device to my XP PC, PC will show connected USB as a
available COM port. If suppose my PC having already two RS232 COM ports,
connected USB device will show as a COM3.

Same functionality I wanted to make in my Windows CE based PC. So that from
my CE application by using WriteFile and ReadFile I can write or read data
from device.

It's impossible to say. "Black Box" generally mean that you have no
idea/don't care what's inside. You need to know a little about what's
inside to know wheter or not it is possible to easilly hook it up to a
CE device.

The term "Client device" is a little ambigous (it has many meanings).
Does the CE device use a host or function interface to communicate
with the "black box"? Do you know what USB class it implements -"CDC"
is a broad standard spanning several different USB classes. You mean
USB serial (Iike in USB Modem)?

Currently I have following drivers in Windows CE Image:
HKEY_LOCAL_MACHINE/Drivers/USB/ClientDevices/Hid
HKEY_LOCAL_MACHINE/Drivers/USB/ClientDevices/Mass_Storage_Class

HKEY_LOCAL_MACHINE/Drivers/USB/FunctionDrivers/Serial_Class

HKEY_LOCAL_MACHINE/Drivers/USB/LoadClienets/Default.

Out of all above where I need to change registry settings for my blackbox
vendor ID and Product ID?

Thanks,
Suresh

My hardware vendor gave product ID and Vendor ID etc... information for USB
Serial Communication.
By creating simple INF file in XP machine we are successfully found black
box from XP machine and able to communicate.

To achieve same functionality in Windows CE 5.0 machine, please explain how
I can do in Windows CE machine- Dölj citerad text -
