Christopher, Please read my response to Cary, below:

Please keep all correspondence on-list. (cc-added) I generally ignore private

You do not want to download dvb-usb-bluebird-01.fw to the FusionHDTV Dual
Digital 4 . Although the usb control API is identical, the internal mechanism
is completely different. The dvb-usb-bluebird-01.fw firmware image doesn't know
how to operate the Dual Digital4 internals... Can you please test your device
in windows and confirm that it still works after downloading that firmware to
As an aside, the Dual Digital4 stores the firmware in an eeprom on-board.
Firmware download for this model is not required, although it should still be
possible. If your unit doesnt work in windows anymore due to the firmware
change, then I can probably release a new firmware image for you in a few days.

I have a driver that should work (in theory) ... I dont want to release it yet,
until I can test it on somebody's machine. There is slight risk of eeprom
corruption due to i2c probes, so I am feeling very cautious about trying this
out in the real world. If you're willing to possibly end up with a paperweight
as a result of testing a driver, then let me know.

Go for it. I wonder what you'll come up with. Just don't do any random i2c
probes! I will make an announcement once my driver is ready and tested, but I
cant say how soon that will be.

I don't know if it makes a difference. I live in Brooklyn. :-)
