It looks like you are missing brackets around the else case.
This patch does seem to fix the problem I described, though admittedly
I haven't exactly figured out how you are supposed to use the ldusb
driver. It looks like I need to first write some magic numbers to
initialize the device before a read will produce useful data. I guess
I need to study Greg KH's Go!Temp driver to figure out what exactly I
am supposed to write to the device.
