I've been using a home brew interface to a DS9490 USB interface for some time now.
I just upgraded to Fedora Core 10 (from FC 3) and see that there is a kernel module for this device (called DS2490). It seems to find the DS9490 (and complains a lot at boot time about devices on the bus!)
Anyway, if this is a "standardized" interface to 1-Wire, I'd like to start using it, but so far, I've yet to find anything about the module's use or interface.
Any help would be appreciated.
