Re: USB drives me nuts

Hi Michael,

With MIDI devices the rule is to try to always plug them into the same USB port.  In XP, anyway, there are a limited number (eleven, I think it was) of MIDI ports available and if you plug the same device into two different USB ports at different times it will wind up having two MIDI ports assigned to it, one to each USB port.  I ran into this problem when I got a Steinberg CC121 controller and got a message that there were no midi ports available.  You can go into the registry and clean out the duplicates, though.

As I said, though, that's XP, and Vista might act differently.

Subject: USB drives me nuts

My Vista notebook has 3 USB ports. I currently use them for:  Soundcard,
Axon Midi controller, Steinberg key, Midi-2-USB, Nanokontrol, Nanokey (until
its usb plug broke off), Nanopad (probably I have forgotten one or two). I
use a passive little hub to plug them all in.

The thing that I wasn't aware of is that apparently it is important to plug
the devices exactly into the ports that were used during the installation.
Otherwise, often they aren't recognized. Today, I spent some time (not for
the first time) to persuade my system to recognize the Axon controller and
the Steinberg key again - each of them had been working before but not
today. This drives me nuts because I find it hard to understand the pattern
of this, much less the reason why this happens. My intuition believes all
devices should work everytime, independent where I plug them in.

Are there simple rules of thumb?
