now running libftdi-1.0 linked against libusb-1.0.

After fighting some other problems, the same thing happens. As soon as in
following expression

#define CHUNKEXP 14
  if (ftdi_read_data_set_chunksize(&ftdic, 1<<(CHUNKEXP)))

CHUNKEXP gets bigger then 14, blocks of data get skipped. Maybe something in
libusb or even the kernel...
