+ <title>Combined ATR/APDU message</title>
+ <para>For some cards the firmware does not send an USB message at
+ the end of the ATR. The ATR and first APDU will be send in one message
+ and the host utility fails to split APDUs and nothing will be traced.
+ A band-aid for the firmware exists and can be found on the mailinglist.
+ <title>Lost bytes</title>
+ <para>For some new high speed cards the firmware can lose bytes. The
+ issue appears to be when the received bytes will be copied to the memory
+ of the USB controller. The workaround is to reduce the size of the buffer.
