I don't use a usb hub. I tried all USB ports on my PC and I always get that message. I just attached a pic of the message in the first post.
I've re-checked the USB ports with my DigiCam and my Synthesizer and they all work just fine.
Hi everybody, The HD500 is connected to the computer via USB. I always get the attached error message. ??? I don't have MIDI cables. Doesn't work the update via USB cable? Thanks
