one of my squaddies posted his x52 to another squaddie because he hated it un-calibrating all the time (gave it away for free and paid the P+P). I'm not sure whether he invested in a usb hub or not but rumble didnt have much luck with it either.
I've tested the x52 around wurzels house and thought I'd show him some of my uber skillz and I just couldn't get anything out of it. Infact it made me look worse than wurzel !!!
CH all the way.
