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:
That allows me to identify+eject the device via its non-volatile serial, but I need it to recycle, not just eject.
I have read this:
I do not understand it.
This has been mentioned in other USB related posts:
It is not relevant to my problem.
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();
