Hi,

I've got a bus enumerator that's similar to usbstor.sys. It enumerates
removable disks. If the disk is completely blank, then the drive loads
with no problems. I can format it and everything is happy, no reboot
required.

But, if at plugin time the disk is formatted, the disk can be
read/written just fine (Autoplay shows the contents right away), but
Windows complains that a reboot is required. I look in Device Manager
and the driver with DN_NEED_REBOOT set is VolSnap.sys.

If the same exact disk comes up as fixed, there's no problem either.

How can I get the removable disk to come up with no reboot (like
usbstor.sys)?

Thanks,
Kevin
