Subject: don't expect to always receive a full frame
X-Git-Tag: v0.100~38
X-Git-Url: http://cvs.zerfleddert.de/cgi-bin/gitweb.cgi/hmcfgusb/commitdiff_plain/bafd75c9511de5b554fb222331b88518ed2ee96e?ds=sidebyside;hp=6c5c2df75ff018417dd6abb38196d998d5fa5b10

don't expect to always receive a full frame

with this the bootloader-workaround can also be removed, as the
bootloader will only send 1 byte, not 64.
