Whew. This morning the USB adapters and gender changers I had ordered finally arrived, so I was all set to try out one of the various solutions I've been reading about here for weeks, and hook up my keyboard, hub, and various other things to my 770... yay :-)

(Side note for conspiracy theorists : four plug shapes and two genders... can you believe the USB standard was NOT designed by and for cable manufacturers ? :-)

Below is the account of much hacking, sawing, drilling, soldering, swearing and whatnot.

Warning : if you've read ALL the relevant threads in the forum, you won't learn much, if anything, in this one. All the ideas implemented have been described by others (and credited, I hope correctly) ; there are only minor variations (depending on what was scavenged, what had what plugs etc.). The main point is to confirm those solutions work, add a few pix to the gallery, and, well, rightful bragging after a day's work :-)
