hmm, there are about 5 different types of firmwares... 
- TWO for minipci cards 
	- fullmac are exclusively for prism54
	- softmac are only for p54
- one for isl3886 chips with a net2280 pci-usb-bridge (your card/stick)
- one for isl3887 chips (they have a native USB-Interface)
- one for conextant's cx3110x (spi interface) (found on some Nokia N800/N770 I think
	Johannes did some work here, but that was long ago)

so stick with prism54.org recommendation 2.5.6.0 ...

(Ad-hoc isn't supported... there was a patch but no review!)

And you always have to bring the interface down to change the mode
it's more a mac80211 thing than p54's fault...

Ad-hoc isn't supported and monitor-mode will filter out anything
except beacons...

Hmm, I found 2 problems and I guess there are some more...
(Will post them later today or tomorrow, my timezone is CEST)

but you'll need:
- wireless-dev git-tree (which can be found here:
http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git )
- the "patch" - utility
- time to test & report...

hmm, do you have usbmon enabled in your kernel? Or is there any other facility
to "monitor" what ndiswrapper or p54 is doing? because this logs are very handy!

hmm, I haven't heard of anyone with success...
