[moved] Nokia E52: problems with the port USB1

[raulrodriguez]

Hello to all,

I’m developing an application on Java ME for Nokia E52, platform S60. I have a problem when I try to open a connection by the next way:

import javax.microedition.io.Connector;
.
.
comm = (StreamConnection)Connector.open(“comm:USB1;baudrate=115200");

It causes the next error:

Symbian OS error: -21

But when I invoke the method as follow (port USB2):

comm = (StreamConnection)Connector.open(“comm:USB2;baudrate=115200");

It works perfectly.

It is possible that the USB1 port is occupied by another application?



Thanks!

if you check the error description for -21: http://wiki.forum.nokia.com/index.php/Error_codes

you could maybe conclude that the port is in use and thus you can not use it.
