USB hot-plug detection

[boki]

Dear All,
There is a voltage drop be detected by USB host controller,
we can recongnize this signal to know a new device, but, what is the
function or API or method in windows programming? ( VC/VB )

Thank you very much for your help.

Best regards,
Boki.

Why don't you ask in a newsgroup where _windows_programming_ is the
topic: comp.os.ms-windows.programmer.win32? C++ _language_ does NOT
have any means to control hardware.

Except, of course, when implementing UB (undefined behavior), where, as I
understand it, your monitor may make toast or your CD drive launch deadly
missiles across the room (depending upon what the evil compiler vendors
thought would be more amusing).

Well, yes, but the problem is, you cannot make sure that it's exactly
what happens by, say, dereferencing a NULL pointer. The beauty of it
is in its unpredictability... Can you call it "control" then?
