The perms do need to change, thanks for noticing that bug. That's not a bug. For starters, we have transport classes that provide generic store methods but can't pass the information on to drivers. For these, we set the attribute to read only even if there is a store method. Even if that weren't the case, how do you know which of UGO wants the write setting? Finally, if you look at the sysfs code, the place where mode settings of the sysfs files are handled doesn't see the show/store methods at all (these are handled at a different layering within the generic driver model).
