发帖数: 11 | 1 how to check how many USB Camera is connected on one computer which has
multiple USB port? For example every time I hooked up a camera onto one USB
port, The New Device Found dialog pops up. After installed it, one new key is
added in Registry. If I installed 4 cameras, I got 4 keys. But when I unplug
1, it seems there is so change in Registry. I can find the information (3
cameras) in *Device Manager*, but how can my software know how many connected
right now.
PS. I just need this information w |
