Issue Description

In Test 4 of ACP_ACP_EXT.1 in the KM PP-Module Supporting Document, Step 9 states Connect a switchable 5 volt power supply with a USB Type-B plug into the TOE KM peripheral device interface.” It is not necessary for the USB plug to be Type-B; any compatible USB connector may be used.

Resolution

The KM PP-Module Supporting Document is modified as follows, with strikethrough indicating deletion and underline indicating addition:

Section 2.1 is modified as follows:

Switchable 5 volt power supply with any compatible USB Type-B plug - used to verify electrical signals are not sent to non-selected computers.


Test 4, Step 9 is modified as follows:

9: Connect a switchable 5 volt power supply with any compatible USB Type-B plug into the TOE KM peripheral device interface. Modulate the 5 volt supply (i.e., cycle on and off) manually at various speeds from approximately one cycle per five seconds to one cycle per second. Verify that no new USB traffic is captured on all non-selected computer USB analyzers.

Justification

See issue description.
