Firmware upload required? * How to trigger special functions, i.e. a builtin mixer? * Which streaming format is used? You could live without the second, but the other two are important. It's basically what the FFADO project does for each firewire interface, but with USB-2.0, each vendor implements his own on-wire protocol, there's no common platform chip. So prepare for a lot of sniffing. (capture the packets your windows driver sends to the box and try to understand. There's isochronous traffic for the audio streaming and non-iso (async) for device handling) If nothing helps: run Windows in a VM (virtualbox?), make a USB passthrough and then reroute the audio/midi ports via netjack (jackd2) back to your Linux machine. Don't know if wine can load drivers, if so, you might be able to debug/sniff the win driver directly. In any case, help from your vendor would be a good thing. Try to contact him and ask for documentation. I bet the answer will be "We don't care about Linux", but if so, please tell us. This way, others could avoid buying Tascam in the future. ;) Cheerio -- mail: a...@thur.de http://adi.thur.de PGP/GPG: key via keyserver USER, n.: The word computer professionals use when they mean "idiot." _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
