[Prism54-devel] 3CRWE154G72

[Cliff Rowley]

Hello :)

I recently bought a 3CRWE154G72 on the chance that it might be one
supported by the prism54 driver (I can't get any orinoco cards cheap
enough where I live).  It appears to be supported, but doesn't actually
work.  I have spend a couple of days researching information on the
problems I've seen - and the general concensus appears to be that either
(a) Linux is handling PCI interrupts incorrectly somehow or (b) my card
is in fact a SoftMac card or (b) some configuration aspect of my laptop
could be preventing it from working.  Unfortunately I cannot disable
ACPI since I am on a ThinkPad laptop that doesn't behave correctly 
without ACPI enabled.

Aside from obviously wanting to determine whether my card is SoftMac or
not, I would also like to offer any help I am capable of providing.  I
have no driver development experience (though I do have C/C++
experience), but I am willing and able to test.

So in short, firstly how do I determine whether my card is SoftMac or
not? (and if not, would shifting devices to different IRQ's help?)  And
secondly, how can I help with this project? :)

Many thanks :)
