USB arrival detector

I'm testing a code that i found on Internet which detects cd-rom arrival. Now i want to change it in order to detect removable disk arrival.

This is the condition but it doesn't work

Code:

---

q.Condition = @"TargetInstance ISA 'Win32_LogicalDisk' and TargetInstance.DriveType = 2"

---

What is q?

q is a WqlEventQuery Class

Try changing this:

Code:

---

q.Condition = @"TargetInstance ISA 'Win32_LogicalDisk' and TargetInstance.DriveType = 2"

---

to this:

Code:

---

q.Condition = @"TargetInstance ISA 'Win32_USBControllerdevice'";
