Hi,
Out of interest, who wrote the USB.Patches devices - and is the source
code to these available?
Source is not available, Be themselves wrote them. AFAIK, the "patches" are
simply some usb related files taken from Dano. So the legality is highly
questionable. In any case, we should not concern ourselves with that too
much seeing that Michael Lotz is progressing so well with the Haiku USB
stack. As was already said, the Haiku USB stack is compatible with BeOS USB
drivers, including the USB Mass Storage driver in our repo. The problem is
that the UMS driver is at the same time an add-on to the SCSI subsystem.
This is most likely the place where it needs to be adjusted. Siarzhuk would
know best... :-)
You are right. The vanilla BeOS SCSI CAM interface was "a bit"
non-standard and I suspect that there will be some work with it. The
"fake" devices reservation is also will be not required, I hope. By the
way, is Haiku SCSI CAM use 6-byte commands by default as BeOS does? If
not - this is also should require some fixing. The command sequence
during initialization can also affect on some of hardware items. The
CD/DVD SCSI command sets are also were problematic due very
"interesting" behavior of "scsi_cd" driver. :-)
