How to 'disconnect' and 'reconnect' an USB device using a VB program ??

[arunb]

Hi,

I am using a USB to Serial converter. The converter works OK for most of the time, but sometimes the converter stops working, the COM port assigned to it is removed from the registery by the Windows OS.

To re-establish the connection the converter needs to be un plugged and then re-plugged.

The OS now detects the converter and assigns the COM port.

Is it possible to unplug and re plug the device using a VB program ??
How do I make the OS start the detection process ??

thanks

Hello arunb,
i realise this was a long time ago, but did you ever find a solution to this problem. I am having the same issue.

Thanks in advance.
