" i0 u1 M$ n2 W, D  E+ V) WDecision: OSM EE conclusion: decision only in the minutes
" a+ P0 `/ N5 E! iDecision 06/6 deleted and replaced by decision 14/4:
If the accessory is designed to the Universal Serial Bus (USB), version 1.0 or 2.0, or IEEE 1394 sets of standards and is provided with a single connector configuration required by those standards, it may be assumed that the accessory is supplied power by an LPS, and thus may use HB material without further test. See also first bullet of 9th paragraph of 4.7.2.2.
Accessories using non-standard USB connection are excluded from this decision.
Confirmed by IEC TC108.
1 o. `$ T4 w7 MPoE and USB 3:
OSM agrees that input from IEC TC108 is needed. Until then PoE and USB 3 should be considered not to be LPS.
