Comment:

 The root cause of this problem is the way that #11845 was fixed.  That
 change (svn 3004) caused ports to be reprobed, even if there was a device
 attached that had been successfully probed and was working; reprobing
 could cause it to stop working, particularly in the case of built-in hubs.

 The fix to this ticket is in svn 3444, which modifies the selftest logic
 so that devices that are already present prior to selftest execution are
 not reprobed, but rather their identification information is displayed.
 With this change, execution of USB selftest is stable in any order,
 whether in diag mode or not.

 svn 3444 add the additional feature of making it easy to invoke the old
 fisheye test, which svn 3004 hid under the hood.  To invoke fisheye:

 {{{
    ok false to diag-switch?    \ diag-switch? is usually already false ...
    ok test /usb:fisheye        \ Fisheye pattern to unpopulated USB root
 ports
    ok test /usb:fisheye/hub    \ Fisheye pattern to unpopulated USB hub
 ports
 }}}
