What do you mean by "room" and what hubs can rasp pi work with? Thanks
the gap between the yellow lines. (crap drawing lol) because of the size of the asic you would have to use one miss one.
[/URL]most use these

Quite expensive ey?... I have one ASICMiner USB for now, but I am looking for expanding my USB army (dafuq lol) so I am just doing some 'homework'...
Any cheaper or I will have to go back to HK during christmas break and get some bargain
Maybe I can bring some back to UK and sell it here 
i have got one of these running ok but i have only been running it for a week with 5 plugged in, but i did solder a 5amp power supply direct to the board. but how long it will last i don't no. i have already killed 4 cheap hubs but not one of these
