Make sure that prism2_srec is also compiled from the CVS sources.  Make
sure that you have PRISM2_NON_VOLATILE_DOWNLOAD uncommented in
driver/modules/hostap_config.h

Also see the kernel log.  It's displayed by the "dmesg" command.

Maybe -ENODEV was returned by the driver.  There are just 6 places where
it's returned (not counting the PCI and PLX drivers).  If dmesg doesn't
show anything useful, you could use binary search to find which function
returned -ENODEV.

Not all kernel messages are logged in /var/log/messages.  dmesg may give
more information.

That's because genesis mode is RAM download.  You should use
RAM-downloadable firmware for that.  But don't attempt flash download
after RAM download - it won't work.
