typo? did you mean "enumerated on the bus but not on device list"?
if yes, the first part is ambiguous in its wording, the enumeration
completes by programming a device number. At this point the device is
only 'attached'.
The fix is correct otherwise, please add my tag if you change the commit
message in a v2.
