This same problem I reported a few months back is still in 2.5p4
I am polling a USB adapter once per second, after a while some sensors come
up missing (thats ok), but then I still get this error:
. . . . . . . . . . . . . . . . . . . . missing buttons
Set([Sensor("/05.893A26000000")])
. . missing buttons Set([Sensor("/05.893A26000000")])
. . missing buttons Set([Sensor("/05.893A26000000")])
. missing buttons Set([Sensor("/05.893A26000000")])
. . . . missing buttons Set([Sensor("/05.893A26000000")])
. missing buttons Set([Sensor("/05.893A26000000")])
. missing buttons Set([Sensor("/05.893A26000000")])
. . . .

AttributeError: 'NoneType' object has no attribute 'split'
at line 375:
self._attrs = dict( [ (n.replace( '.', '_' ), self._usePath + '/' + n )
for n in owfs_get( self._usePath ).split( ',' ) ]
So owfs_get is returning None.. everything goes downhill from there.
