Jim, Does anything else in the directory hierarchy return good data? If not, this may indicate that the fuse data access functions are broken. In other things work, then it is more likely something in the owfs code.
owhttp does not depend on fuse, so it will check the lower level access to the device. jerry On 08/27/2010 01:32 PM, Jim Kusznir wrote: > We have tested with an owfs mount, and it returned nothing in memory > (when we know there is something there), so its also broke at that > level.
