Hi William and Peter again… Can it actually be a module problem if it is creating the directories for the devices one wire bus, just not detecting the devices?
Thanks!

My understanding was that 3.8 and above kernels needed no module, simply the DTO. It was pre 3.8 kernels that required the kernel module. Or am I missing something there? Certainly, every page I'm reading referring to 3.8 kernel 1Wire has absolutely no reference to kernel modules. So, perhaps, but if there is something wrong with the device tree blob file, the driver wont auto load. Which would give us an indication as to what's wrong.

It should look something like( more or less ) with hopefully the generic one-wire module also loaded. My understanding was that 3.8 and above kernels needed no module, simply the DTO.
