Im making a WPF app.

Im looking for a way to list all plugged in USB devices (disks!) in my comboBox.

I can list all drives using DriveInfo.GetDrives(), but is there a simple way to filter that to USB devices?

thanx

 foreach (DriveInfo drive in DriveInfo.GetDrives())
 {
     if (drive.DriveType == DriveType.Removable)
     {
      ..
     }
 }

Be careful with this that you don't (occasionally, never with a debugger attached) get a horrible messagebox from somewhere deep in Windows asking you to insert a disk into a drive. – Will Dean Jul 27 '10 at 12:38
i have additional question. My combobox had binding to property (type List) on my viewmodel. It works fine, but if i plug in USB disk i have to reload the window in order to repopulate combobox. Is there a way that i could repopulate combobox once the USB devide is plugged in/ out ? – no9 Jul 28 '10 at 05:50
also i shrinked the code u gave me to: return DriveInfo.GetDrives().Where(x => x.DriveType == DriveType.Removable).ToList(); – no9 Jul 28 '10 at 07:14
Use ObservableCollection in viewmodel to bind to the Combobox. Create a DispatcherTimer with some interval to check for Drives, if any new drives found add that to the observablecollection; this is will displayed in the UI. – Ragunathan Jul 28 '10 at 07:19

This does not work with some external hard drives. At the moment the only way to detect if it is a hard disk connected via USB is to use some ugly WMI stuff. You can see a code sample at http://stackoverflow.com/questions/3331043/get-list-of-connected-usb-devices – seveves Aug 14 '15 at 11:26
Isn't this return all the removable drives? including SATA which is not a USB? – AaA Mar 24 '18 at 13:38
