I have finished the conversion of the UMASS driver to my new USB API. If you
have got a UMASS device laying around, and want to help the USB project,
please give the new driver a test.
I want you to collect some statistics first:
dd if=/dev/daX of=/dev/null bs=131072
dd if=/dev/daX of=/dev/null bs=524288
What is the maximum speed you get before and after installing the driver?
What is the maximum CPU load reported by "ps aux" before and after installing
the driver [while doing the "dd"]?
# How to install the new USB driver
# on FreeBSD 6.x / 7.x:
# First get all the sources
# (you need /usr/ports/devel/subversion installed):
svn --username anonsvn --password anonsvn \
# The following commands will
# install the driver on FreeBSD 6.x/7.x:
make S=../src package
# Then build a new kernel (with modules)
NOTE: You still can't detach the UMASS device while it is in use, but this
problem is being worked on.
