[quote=”FOH” post=773]USB by default does not allow multiple active units. That is the unfortunate artifact of the obsolesce of good ‘ol Firewire….[/quote]
Where have you seen that ?
I (and friends) can of course use several USB soundcards on the same computer, even with a USB Hub, all depends on the driver.
For example, I can aggregate 3 ESI Gigaport HD with ASIO4All on Windows or with the aggregate feature in OS X, but only one LP-16 is actually recognized and can be used on a computer (request made a few months ago).
For LP-16 + LR-16 it will depend also of the drivers…
