Hi,

I'm trying simulate a device unplug and re-plug in one interface driver of
the composite device. On Windows XP, there is no problem using
IOCTL_INTERNAL_USB_CYCLE_PORT request but IoCallDriver function returns
0xc000000d (invalid parameter) on Windows 2000.

It look there is a problem to use IOCTL_INTERNAL_USB_CYCLE_PORT on composite
device and Windows 2000.

Is there any way to simulate a device unplug and re-plug on composite device
for Window2K and Windows 98SE?

Any comments welcome.
Thank in advance.

Jeth
