I have developed a usb mass storage removable disk, without a remote
wakeup function.

When I pluged this disk into a PC whose OS is winXP, the USB host
would send a suspend signal two times.
The first suspend signal was send out when the disk was just plug in,
and the second happened when I delete the disk in the right icon.

why the USB host send the suspend signal in the first time, and it
happened just two times?

It's thankful for your reply.
