Sounds plausible. I wasn't aware of the particular 8-byte-garbage symptom (or heard of it and forgot it). Some people (regardless if Windows, OS X, or Linux users) were able to make their PL3507 work with new firmware: http://wiki.linux1394.org/FirmwareDownload Very old revisions of the chip don't support firmware upload. And some boards with newer revisions apparently prevent firmware upload with a resistor: http://club.cdfreaks.com/showthread.php?p=957178 -- Stefan Richter -=====-=-=== =--= ==-== http://arcgraph.de/sr/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
