************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Does your app run off the USB device?

Does your app run off the USB device?

The message is thrown as soon as I run the app, as soon as it starts to
use the USB port I suppose...

How are you accessing the USB device? Can you display an OpenFileDialog from
within your app and browse to the USB device?

Hi CT,

Thanks to your last question I found the solution to my problem...

The app is to be used with a specific USB port (port 0?). In fact, when
I disconnect the device or I connect it to an "invalid" USB port, the
app says something like "ERROR N° : 901 bMICROCHIP_OpenUSB 0"... So I
connected the device to another USB port on my computer, and now... it
works...

Many thanx !!!
and have a nice day !
Victor
