Dear all,

I'm working on a way to read in data form ADCs to a PC via the UM245R.
It is working, but i could only achieve 630 KB/s compared to the
theoretical speed of the device (1MB/s with d2xx drivers). I'm
assuming that my code is inefficient, since I'm only a hobbist at
programming.

IIUC, in the time you measure, you are including the printf calls to the
console.  Don't know how much this influences the result.

Thomas
