Here’s our FireWire driver for OHCI cameras:
Currently requires Mindready LLA, but there’s full source
code for our camera driver, including multiple camera and
hot plugging support. It’s a QNX resource manager; when
running, cameras appear under “/dev/fw0”.
It probably isn’t that big a job to convert this to work
without the Mindready LLA. All the LLA is doing is talking
to the OHCI chip and managing buffer queueing. We had to
do all the bus management ourselves.

MindReady decided today to port their FireWire driver and IIDC module

Just found this old thread. Maybe they decided on this after my company
reported to them that our preliminary testing showed that it worked?
And if they had only sold a single-digit worth of licenses (as previously
reported) then no one but my company must have a license!
Despite this, our negotiated price just changed under our feet and some
items TRIPLED!!! in price with our latest order. Needless to say, there are
some VERY unhappy people here. We were already paying a premium, even
committing to using MindReady’s very expensive boards, but now the pricing
is totally ridiculous.
I really think the time has come for someone (and it will likely be me if my
company ends up doing it) to write/port a working alternative that works
with IIDC cameras and just release it into the public domain to kill
MindReady once and for all unless they come to their senses on pricing. I
don’t mind paying a reasonable amount for a board and driver (I had been
paying $715 for the board, LLA and IIDC stack) but now the pricing is
My company has in the past implemented our own camera drivers, and it looks
like we have to do it again. We have expertise in this area and have always
ended with a robust driver that gives better performance than the board
manufacturer’s drivers under other OS’s. Previously the drivers were
considered proprietary and we kept them to ourselves, but if we have to do
it this time for 1394 I think I’ll throw it out to the masses this time.
