On the topic of firmware updating, I also have a project for a
firmware-flashing API that supports both BTC and BenQ DVD burners (in theory,
anyway-- it's 100% untested at this point). It uses libscg (indirectly,
though calls to fwscsi_*) to access the devices, but uses regular old /dev
device names (or the SCSI number things). If anyone wants a snapshot (or CVS
access, to contribute), let me know and I'll post it in my public_html...
Current plugins:
Image formats: CVT, Intel HEX, and BenQ EXE
User interfaces: 'fwflash' (commandline)
Devices:
DVD+-RW: BTC and BenQ
Build output:
lib/libfwflash.so
lib/libfwflashscsi.so
lib/fwflash/device/dvdrw_benq.so
lib/fwflash/device/dvdrw_btc.so
lib/fwflash/imgfmt/benq_exe.so
lib/fwflash/imgfmt/cvt.so
lib/fwflash/imgfmt/intel_hex.so
bin/fwflash
