Hi Tom, > > Hi > > I'm trying to use the ufs-bsg transport for SSD debug tool and facing > an issue where there is no ufs-bsg node created either in /dev or > /dev/bsg. ufs-bsg is a bsg node designed to communicate with a ufs devices, using non-scsi commands, but a ufs-specific protocol, which your ssd doesn't speak. So you can't use it with any non-ufs devices. To create it you need to open its config switch - CONFIG_SCSI_UFS_BSG. Maybe try using the sg driver?
