A Disk puzzle!!!

Hello all tops,

I can use GetDriveType to get the driver type, such as Fixed Disk, CD-ROM.

But I can’t judge if the current disk is a usb disk because GetDriveType
return Fixed Disk.

Is there any way I can follow to judge a usb disk? either by kernel driver
or by app program?

Any hints?

Anthony

One way to determine the bus type a storage device is using is to use
IOCTL_STORAGE_QUERY_PROPERTY, and ask for the adapter properties. In
the
returned structure is a bustype field; USB is one of the supported
reported
bus types.
