VCP (Virtual COM Port) Name?

matt_Damon
Hello,

When a VCP device is connect, what will be the new com port number on
MINI2440?
The VCP driver is installed successfully but not able to figure out the new
com port number.

Hello Matt,

I'm using an FTDI chip as VCP.
It occurs at $device\COM10 in CE6.0.

I also use a FTDI multiserial, but if I connect to a USB hub I errors. For
example, serial ports are disappearing and I can not open them ...
This happens on both WinCE 5 to 6

Hello: 
also I am trying to use ftdi_ser.dll for ARM. and it does not appear by any
place a new port! . 
It tries with all the ports. 
In CE6.0 this qualified from the port com1 to the port com9. when attempt
to use the port com10 says to me that it is not a name qualified like com
port. I am using compact framework with visual C# studio 2008 somebody
already had some experience with this?

I got it working,
-Download the driver from FTDI;
http://www.ftdichip.com/Drivers/VCP/WinCE/CE60/ARMv4VCPDriver.zip
-or for ce50
http://www.ftdichip.com/Drivers/VCP/WinCE/CE4252/ARMv4VCPDriver.zip
-Copy Ftdi_ser.dll and ftdiport.inf to the \Windows directory of you
Friendlyarm
-Plugin your ftdi device and on the screen comes an messagebox
"Unindentified USB device" , type now in this box ftdi_ser and it should
work.
-For me the port occurs with the name; $device\COM10.

In Vb i'm using the following to get all the port names in an array, i
believe the syntax is almost the same in C#.

Dim nameArray() As String
nameArray = System.IO.Ports.SerialPort.GetPortNames

Have fun.

hello 
thank you very much! 
it was of much aid! the error that was committing, was that only it placed
COM10, time to put $divece\COM10, 

        serialPort1.PortName = $divece\COM10

is why it did not detect the door to me. 

for see them,
 
string[] ports = SerialPort.GetPortNames();

            foreach (string port in ports)
            {
                textBox1.Text = ports[4] ;
            } 
andres thanks

DIVICE   !! NOT DIVECE.. ;-)

has anyone tried to connect the multiserial to a USB hub?
WinCE fails to correctly recognize the COM ports

Edje11
I don't know exact what you mean with "multiserial" , but the FT2232C works
fine here with ce60
The FT2232C is an dual serial and gives me $device\COM10, $device\COM11

jeangr
I use the FT4232H chip as multiserial with 4 serial ports. I'm using both
the driver D2XX (http://www.ftdichip.com/Drivers/D2XX.htm) that the VCP
(http://www.ftdichip.com/Drivers/VCP.htm) without problems. My problem is
that if I put in the middle a USB hub (mini2440 only has a USB port!), I
can not access the ports correctly.
I am clear?

hi Edje11


I put into my image nk.bin with platform builder 2 files: ftdi_ser.dll and
ftdiport.inf and typed in textbox "ftdi_ser.dll" (the window doen't
disappear and I have to close it), but every time I reboot with the device
connected, this not detected. I have to disconnect and reconnect ...
Why?

jeangr
every usb device connected at the WinceCE startup is not detected.I have to
disconnect and reconnect it...
Is it possibile that my image made with platform builder is wrong?
