Any ideas what I could have done wrong?
it's not amazingly hard, this, there's not actually a lot to do, so the number of things wrong will be very small.
can you take a picture and make it available online, also compare against the photo here:

btw if you haven't re-flashed the firmware at all, then by default it will come up with LD2 blinking happily. check first that that's what happens by returning the U5V jumper and plugging in a mini-usb cable.
btw you should *NOT* plug in a mini-usb cable at the same time as the USB cable across PA12 and PA11!
also make sure BOOT0 is shorted to E5V *before* pressing reset, then hold reset for at least 0.5 seconds, *then* release reset, then release BOOT0 screwdriver-short.
hey, I got it finally. I think I made something wrong with the screwdriver (noob!), but after some more attempts it worked and I got the miniblink working.
yaaaa sounds familiar :)
I will go on with the usb-rewrite stuff now, and see how it works.
you should actually be able to use libopencm3 master, now, because some usb commits for stm32f072 were made last week.
