On a desktop machine where : the USB does get detected, the uhci0: line above shows a port address and : a valid irq. The basic problem is that the BIOS isn't assigning resources for this card and expecting the OS to do it. FreeBSD does this minimially right now, and needs lots of help. : So only -current has the good stuff? :) I'm on -stable and would rather : not switch to -current. But thanks for the pointer, I'll go grab code and : take a look-see. You might be able to do a half solution in stable that would work well enough for you. You'll basically have to pick an arbitrary hunk if high memory and use that for the memory ranges that this part uses. The interrupt routing is a little harder since you can't just pick one.
