I’m trying to update the firmware of my LP-16, current version is V-8503 on an iMac with OSX V 10.10.5.

The LP-16 is detected by OSX as an audio interface and it says USB interface mode on the device.

The does NOT recognize the device, so I’m not able to update the firmware.

I tried the following:
– shut down all audio software
– unplugged all usb devices
– started the firmware updater, plugged in LP-16 and switched it on
– tried it the other way around too, plug in, switch on, start the firmware updater.
– nothing happens…

Thanx for any advice…
