WOOHOO!!! MY CABLES CAME TODAY!!! My 6k now rivals laptops!
*goes and buys every usb device he can find- ethernet, bluetooth, mice, hubs, card readers...*
My USB flash disk and a mini-hub worked out the box, my usb mouse lights up (need to find out how to get it to do something with QPE) and my SL-5500 will charge off it (I think I messed up the 5500's USB settings ).
A big thankyou to Trisoft, StreamlineCPUs, and of course, Euroclie.
