You could just look for DriveType.Removable with DriveInfo.GetDrives

var removableDrives = DriveInfo.GetDrives()
                               .Where(x => x.DriveType == DriveType.Removable)
                               .Select(x => x.RootDirectory)
                               .ToList();

if (removableDrives.Any())
{
   string myPath = Path.Combine(removableDrives[0].FullName, "Config1.txt");
}

Obviously you have to deal with the case that you have no (or multiple) removable drives, however I'll leave these details up to you.

DriveType Enumeration

Removable

The drive is a removable storage device, such as a floppy disk drive or a USB flash drive.

DriveInfo.GetDrives Method ()

Retrieves the drive names of all logical drives on a computer

Remarks

This method retrieves all logical drive names on a computer. You can use this information to iterate through the array and obtain information on the drives using other DriveInfo methods and properties. Use the IsReady property to test whether a drive is ready because using this method on a drive that is not ready will throw a IOException.

You can get all removable drives, and then get their drive letter like this:

 foreach (DriveInfo drive in DriveInfo.GetDrives())
 {
     if (drive.DriveType == DriveType.Removable)
     {
        Console.WriteLine(drive.Name);
     }
 }
