while at the issue of reading stuff from devices in windows ...
there are also weird problems with libusb on windows. seems that there are
some quirks in windows that prevent the hi-speed use of such ports (usb is
serial as well....)
im wondering if there are any special calls in the windows api that need to be
called first, to set certain parameters first, like for buffering?
