I have no USB sound card. Perhaps someone else can answer that
question.
There *are* reported latency problems with USB, ALSA and JACK due to
isochronous USB data transfers and JACK's need for a constant power of
two buffer size. IIUC, USB sends a block every 1ms. With some sample
rates this does not result in a constant number of samples in every
block. Progress has been made with certain specific devices (usx2y),
but I believe the general problem still remains.
These issues seem to become more intrusive at lower latencies. But, I
really don't know what the limits are for your device.
