In general, you can't. They're hardwired. You'll need to buy an extra USB adapter. There are a few PCMCIA ones, like: http://www.byterunner.com/byterunner/category=PCMCIA+USB+and+Firewire+Cards http://shopping.uol.com.br/pcmcia-usb.html?nortrk=1&url=/index.html&lout=47,49&psid=1#rmcl There are also some models for Express Card bus. Just be sure to buy one that will work with your notebook (if you're in doubt, you may see http://en.wikipedia.org/wiki/ExpressCard). > > Att, > Daniel Bastos Moraes > Graduando em Ciência da Computação - Universidade Tiradentes > +55 79 88455531 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
