Yep, I went through this conumdrum a couple of weeks ago when I wanted to connect my lovely new Yoshimi Pi to my PC (in this case USB A at both ends, but once again MIDI to MIDI).
I had the same issue when I was stuck in Holland :)
As resources were limited to what happened to have handy, I ended up plugging my little Keystep USB keyboard into the Yoshimi-Pi, and the audio outputs from my Yoshimi-Pi into the audio inputs on the computer.
This of course meant no MIDI sync with the Pi and that proved surprisingly challenging to work with, especially as the computer I was using at the time had issues with audio in general.
USB MIDI is brilliant when all set up with a DAW in the middle to sync and control everything but at the risk of repeating myself (and Martin) again, I do think it was a significant failing that when USB MIDI came along trivial device-to-device communication was effectively dismissed, especially given that it was such a central tenet of conventional MIDI use.
I've had to built two separate 'networks' for MIDI in the studio; one all USB, the other all DIN, and I've got a Kenton USB Host MkII (a wise impulse-buy at the last Synthfest!) floating about in there to patch in if necessary to bridge between the two.
At the very least I think the standard should have dictated that connecting two devices together using a double-ended type A cable should be the equivalent of using a pair of DIN cables for the same purpose, and a 'USB MIDI thru' port would have been great to see manufacturers adopt.
