I followed your instructions Arturia instructions.
Connected the cable from "Clock In" to "Clock Reset Out", powered on, disconnected.
Removed the Arturia device from device manager. Gone.
I also tried to remove the "KeyStep Pro Firmware Updater".... this one appears always when reconnecting.
I downloaded MIDI Control Center again, reinstalled.
I also downloaded a new copy of the firmware file.
Same result.
Software says things like:
"Can not open the device"
"Could not get firmware revision"
"There was an error during the burn process: Cannot find device id"
The unit does not work.
Any other ideas?
Have in mind that yesterday when I bought the unit, it booted with "Vegas mode", then I plugged it to the computer (as you have a paper in the unit says: "before use, please update firmware".)
I plugged the unit, the firmware started uploading up to 50% and now the unit does no longer have lights.
I have tried with differente USB ports 2.0, 3.0, all direct. (no hubs).
I also tried with another Windows PC and a couple of MACs.. same results.
Sad,
Alejandro.-
