What does /sbin/lspci show?  The card I have (DWL-G650) shows:

02:00.0 Network controller: Intersil Corporation Intersil ISL3890 [Prism
GT/Prism Duette] (rev 01)

This works well with the prism54 driver.  Not sure that the prism54
driver supports your particular chip set or not.

I suspect that the driver you are using does not support the scan
option.  If there is an alternative driver available maybe that will
work for your chip set.  I don't think ndiswrapper which uses windows
drivers will support the scan mode.  I have read that it does not work
with kismet.
