If you assume that USB can transfer 1MByte per second (in USB2 High Speed
mode, i.e. 12Mbit/sec), then you can transfer 128Kbytes in 125 milliseconds.
Ten seconds data transfer time on top of the 80 seconds for data transfer -
roughly a minute and a half best case. You're probably looking at a maximum of
two minutes worst case - an eighth of the time it'd take to do the same thing
over RS232.
That's 1MB/sec in Full-Speed mode. High-Speed mode would be more like
20-30MB/sec, if the device can supply data that fast.
