 > One more test that finally throws some light into the problem:  we have
 modified the wireless firmware to reattach to USB '''before''' waking up
 the host, instead of waiting for the host to issue the request.  At the
 time of this writing we've done over 55 successful suspend/resume
 iterations on [http://dev.laptop.org/ticket/1752#comment:8 xo2], the same
 xo on which we could not do more than 10 before.

 Excellent!  Are you able to share this firmware with me for testing here?

 > *Suggested fix:*  Have EC send the 'USB attach' signal to the wireless
 module '''before '''waking up the host.

 Richard, if you're able to get me an EC (I can brick-test myself) update
 that does this, it would be a massive help..
