I am expecting to use an AT90USBKey for a project.
From a prior thread, my recollection is that there are connector issues, but I couldn't quite follow the thread. I've done some more reading since.

Is there a standard cable that will connect the thing labeled "USB MiniAB" to a USB port on a PC?

Did Atmel do something evil with the port pin connections that will cause me problems?

Is 8 MHz the fastest clock that will work?
The Hardware User Guide mentions 12 and 16 MHz, but it also says that the internal voltage is 3.3V and a diagram in the spec sheet for the AT90USB1287 chip says that 12 MHz is too fast at 3.3V.

Edit: fixed tipo

[at least in the units I have] Atmel provided the needed adapter to a "standard" cable.

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

That is good to know.

Also, I'll want some of the smarts to be on the PC-side.
What are others using for PC-side code?
I'm considering using pyUSB.
Any recommendations?

You can find a set of 6 AT90USBKEY port adapters on my site. Link is below.
