Really don't know what to tell you. I googled for awhile and found that people just did the nousb and nofirewire and theirs worked. So I don't know. Other then maybe 4 or 5 places your laptop isn't exactly well documented with linux.
Which is also a mistake I made cause pcmcia doesn't work for me too well on this ze4325. Now I wish I had bought a dell. But for the price that my laptop was, no pcmcia until it's supported isn't that big of a deal. It's still a badass laptop. Problem with laptops, they aren't exactly commodity hardware. So support for other OS's is limited to running.
I really wish I could help more then that. It's not really linux's fault, if hardware manufacturers would be more cooperative, things like this wouldn't happen as much. But hey. Thing's aren't going to change overnight. Oh well.
