Question

I\'d like to cycle (simulate unplug and re-inserting) a USB device (modem) after a certain event has fired. I found a sample on codeproject:

Answer 1

Got it working by using a commandline tool called devcon, which I then called from code.

Dropped devcon.exe into one of the system paths so it works everywhere.

Devcon: devcon

called: DEVCON Remove *usb"*MI_01"

then called: DEVCON rescan

code:

 System.Diagnostics.Process proc = new System.Diagnostics.Process();
 proc.StartInfo.FileName = "DEVCON";
 proc.StartInfo.Arguments = "Remove *usb"*MI_01";
 proc.StartInfo.RedirectStandardError = true;
 proc.StartInfo.RedirectStandardOutput = true;
 proc.StartInfo.UseShellExecute = false;
 proc.Start();
