Good call on the Wii Linux there are tons of drivers for it and if you buy a hub just make sure it supports linux, simply check the box before you buy it and you are good to go. Or just buy a plug and play one and then it doesnt matter but they are always limited to 4 ports so the max you could have is 8 ports on your Wii. 4 coming off of each port, for a total of 8, but who needs more than 8 usb ports on a Wii. I mean can someone seriously tell me a list of more than 8 usb items you would need to have hooked up at all times? The best I can do is cooling fan, keyboard, usb pen drive, mic, camera, Rockband Dongles (Split off to hold drums and bass or mic), Tony Hawk Ride Dongle, and I have nothing for the last slot and this is with 2 mics plugged in. I guess you could plug in a second pen drive or a USB mass storage device. Anyways I suggest you get 2 cheap generic plug and play 4 port hubs and some velcro tape and tape the velcro to each side of the Wii (use velcro tape cause it comes off easy and leaves no residue and is easily hidden so it keeps the sleek look of the Wii) and then Velcro tape the bottom of each hub and then mount one on each side of the Wii and plug them in and voila you have 8 ports and a still sleek looking Wii without a ton of clutter around your Wii. When I did mine like this I faced the ports front for easy access but that is up to you. The only downside is that you have to use the intercooler cooling fan that runs off the power cord cause there is no place to mount the fan on the port in back for a traditional USB cooling fan. But you can still use the normal USB cooling fan stand. Between the intercooler and the stand fan my Wii's thermostat never goes above 38C and therefore the LEDs stay Blue or Green. Oh its a modded case if you didn't figure that out. I have had good luck with the hubs other than the 1/2 and 3/4 issue I mentioned earlier but that can be avoided just by paying attention to what you plug into what ports. No big deal. Hope this helps. Talk to you later.
Sincerely,
