Hadn't done that before. Was using the zadig driver install/update method. I uninstalled the device and deleted associated driver then used your link to install the 64bit version of the SL driver. Device now shows up on COM5. Is that where it's supposed to be instead of USB?
When I tell MM to scan for new hardware it shows up along with my GPU (again for some reason). Will try to start mining here shortly and let you know.
Thanks!
The driver I linked is the PROPER driver for your RBox so you should be good to go.
COM5 is one of many USB "ports" on your computer, the more USB devices you add, the more COM channels will be used. My 3d printer connected via USB communicates (COM) over COM4 currently. If I swapped USB ports, the COM# will change accordingly.
