Good idea using USB, but these device make minimal use of the USB bandwidth.
1.2 kSps continuous and 8 kSps burst to a 4K buffer. That's far far below
USB capability suggesting that the processor doing the USB conversion is the
bottleneck (else why burst to a buffer).

USB2 has the promise of making MSps Flash converters available.

But, at 12 bits, a good start.
