[Pcsclite-muscle] Possible cause for error "CCID_Receive Activity aborted by Host"

[Umberto Rustichelli]

Hi all,

during a signature stree test, I recently encountered this 
non-replicable error in the logs (all the USB smart cards connected to a 
USB hub stopped working):

pcscd: commands.c:1245:CCID_Receive Activity aborted by Host

I'm not sure but it seems that this comes from commands.c -> ccid.c (old 
versions, sorry).

in ccid.c, function CCID_Receive:
if (cmd[STATUS_OFFSET] & CCID_COMMAND_FAILED)
         {
                 ccid_error(cmd[ERROR_OFFSET], __FILE__, __LINE__, 
__FUNCTION__);
                 ....
         }
...in ccid.c, function ccid_error:
case 0xFF:
                         text = "Activity aborted by Host";
                         break;

So, the command status (cmd[STATUS_OFFSET]) is 0xFF.

I've never seen this!
What is it/may be in terms of hardware? What could be the actual cause?
