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.
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
