Below are some comments on the latest uas r03a draft doc.
sec. 4.3, 2nd to last paragraph, 2nd to last sentence: reads "After
the last byte of data is transferred and acknowledged, the UAS target
device shall return a SENSE IU on the Status pipe to indicate command
completion." However, for a "no-data" command, there is no statement
of when the SENSE IU shall be returned (as there will be no "last byte
of data ... transferred and acknowledged..."
sec. 6.2.3, sec. 6.2.4, sec. 6.2.7: These sections don't contain the
statement requiring these IUs to be in their own USB packet (as stated
for COMMAND IU, SENSE IU and RESPONSE IU. Either this statement
should be included "The XXX IU shall be contained in a single USB
packet and shall not share a USB packet with any other Information
Unit.". Or it should be stated explicitly that these IUs are allowed
to be combined in a single USB packet.
