There may be some hiccups with getting the FX2 firmware going on this
device. There are significant changes in the FX2 firmware between a
29xxx and a 24xxx device - enough so that firmware for one variant
simply won't work on the other - and I imagine it's likely to be a
troublespot different in this case. I seriously doubt that the 29xxx or
24xxx specific FX2 firmware would even work on this device.
That is not to say you shouldn't give this a try. It's certainly what I
would do. It's also possible that your device has the needed FX2
firmware resident in flash somewhere in which case the pvrusb2 driver
will probably skip any attempt to send the FX2 firmware. But in any
case this is a step in the initialization where things might stumble.
If it appears that you do need the correct FX2 firmware, you might try
running through the "manual extraction process" documented on the
