Our standard linux version is redhat 5.3 (old) but we have one machine that’s running RH6 (kernel 2.6.32-71) which is supposed to support USB 3.0 and this chipset (according to the docs). I can find that card with “lspci” (output below) but it won’t recognize anything connected to it. Is there something else that I need to do?
