Ok, I don't really know much about ASIO, but I get the impression it
accesses the hardware directly, and hence each device needs a specific
driver.
On Linux, ALSA accesses the hardware. Jack sits above this and provides
a low-latency sound server.
ASIO works around limitations in the standard windows sound API
(DirectSound?) that aren't present in ALSA.
So - you have nothing to worry about other than whether the device
is supported under Linux. If it is USB Audio class compliant, it
will show up as an ALSA soundcard. If not, you need a specific ALSA
driver for it.
You shouldn't need Jack unless you need a low-latency sound server, but
it doesn't sound like you do.
You might, however, want to look at realtime kernels to prevent audio
dropouts when the computer is busy.
