Comment(by andy):

 Yeah.  I made a patchset last night that reduces the probability of this
 down to 10% rather than 50%.

 There's a big fat warning in the USB device code that it is really time
 critical and not to printf() there... we added some I2C transaction for
 current limit on that code path in a recent patch...

 Why shifting that out didn't fix it 100% I dunno, but 90% is better than
 what we got.  I guess this might always have been there at 10%
 probability.
