Well, look for the file that creates the "fg_DIR_615_H1_ralink_rt3352_soc" 
machine. Are there any "pci" related things in there? Anything related to 
"scsi" ? Is it using any of the macros starting with "IF_" ? E.g. IF_SD, 
IF_VIRTIO, IF_IDE or IF_SCSI? ... that would be an indication what kind of 
device your machine supports.
