lsscsi has been "CONFIG_SYSFS_DEPRECATED_V2" tolerant since version 0.21 released 20080710. The current version is 0.23 released 20091201 which will soon be displaced by 0.24 to cope with the most recent breakages.
Writing a user space tool that relies on sysfs structure and contents, stable over the whole lk 2.6 series, is impossible. For a history of my pain with lsscsi see its ChangeLog.
Happily most of my tools are based on an ioctl! SG_IO was a suggestion from Joerg Schilling and has now found its way into most block devices. Now it has a new lease of life in the bsg driver.
