ything different. So can you please send me your patches?
(X) the patch to legotower.c to get the select()-syscall
(X) the patch to get legos-0.2.6-linux-usb-fastdl-sched working
with brickOS-0.2.6.09
(X) the patch to modify lnpd to support the device-file
with
(X) comments to explain the changes
(X) only the necessary changes
or
( ) all changes including indentation-changes
Thanks
