 "ps" prints brackets when process arguments are not available to read.
This is typical for kernel threads. scsi_eh_5 is a kernel thread, a SCSI
Error Handler. It is spawned for each SCSI host in computer (there
should be EH thread for each /sys/class/scsi_host/* )

 Probably yes. USB Mass Storage uses various SCSI command sets. Just
like SATA, FC.
