Does anyone have any idea how to obtain the bus type and bus speed from a
scsi device?  I have a U-160 drive connected to a Adaptec AHA2940 and I need
to obtain the Bus speed and the bus type from the device.  Looking through
the SCSI-2 specs the inquiry data of a device doesn't contain this
information.  It appears that the information is obtained by the host
adapter at boot up time and there doesn't appear to be a way of obtaining
this information after boot.  Any help would be greatly appreciated.
