Could you have tried my new USB driver and see if the problem is the same?
#
# First get all the sources
# (you need /usr/ports/devel/subversion installed)
#
svn --username anonsvn --password anonsvn \
checkout svn://svn.turbocat.net/i4b
#
# The following commands will
# install the driver on FreeBSD:
#
cd i4b/trunk/i4b/FreeBSD.usb
make S=../src package
make install
#
# Then build a new kernel (with modules).
#
When the device hangs, turn on USB debugging:
sysctl hw.usb.umass.debug=-1
--HPS
