When it comes to SCSI Read Format Capacities command, the gadget
driver gives attention condition error in
check_command() in the code snippet below, and the command is not
processed by do_read_format_capacities().
if (curlun && curlun->unit_attention_data != SS_NO_SENSE &&
fsg->cmnd[0] != INQUIRY &&
fsg->cmnd[0] != REQUEST_SENSE) {
curlun->sense_data = curlun->unit_attention_data;
curlun->unit_attention_data = SS_NO_SENSE;
return -EINVAL;
}
Besides the code snippet, the only place that sets unit_attention data
to SS_NO_SENSE is in handle_exception(). How is UDC driver able to
overcome this problem? SCSI READ CAPACITY also has the same attention
condition problem. What can i do now?
