Hi Everyone,
 
I'm new to this forum so please go easy on me! I'm having a problem with X1 Producer. It keeps giving me this message:
 
"USB Audio Device
 
The above Audio/MIDI device was disconnected from your system. Would you like SONAR to reroute these outputs to an available device?
Clicking 'NO' allows SONAR to remember output settings to this device.
Note: If playback is in progress, clicking 'Yes' will stop the transport. "
 
And then I lose function of one or more of my USB devices.
USB devices I'm using are a Line 6 PocketPod, Focusrite VRM Box, Presonus Faderport, and an M-Audio Keystation 49.
I've looked in the device manager, and it shows that there is 500mA per port available, and I'm not even close to using that. I unchecked the "Allow the computer to turn this device off to save power" box in Power Management.
I tried Microsoft's suggestion of creating a "DisableSelectiveSuspend" setting in the registry. Still no luck.
I'm running Windows XP with Service Pack 3.
 
Any suggestions would be very welcome PLEASE!!!
 
 

forget it I did not read the post correctly.

you can rule out the fader port and controller AFA the audio error, I get the message if one of my audio devices becomes disconnected/malfunctions before I launch SOnar, or if it happens when sonar is playing..

1..are you using a USB powered hub?  check obvious connections and power

2. do you have the latest drivers for all four devices?

3. check usb cables for integrity and firm seating 

It also could be related to having the midi devices plugged into a different USB port than where they were in the original project.  It may be looking for a device in 1 port that is now connected via another.  It's good practice to mark your ports to keep the connections in the same place.

a Line 6 PocketPod, Focusrite VRM Box

 
Sure sounds like a power-management issue... 
Make sure these devices aren't connected to a USB-3 port.
 
I'd connect a single USB device (the one used as your primary audio interface)... and make sure playback works as expected.  Then connect the other USB units... one at a time

Totally classic stupid chuckebaby response deleted.

well I wont presume to know his set up but i would assume he is using the line 6 as an fx for his guitar

the VRM for monitoring his mixdown

the fader port for track and mix control no audio there

and the maudio for midi input, (i was too lazy to look it up and see if it has audio capabilities)

of course if he is using AISO then he can only use one device as his audio at a time, and if hes recording thru the POD then he has to be monitoring through it at the same time

but i also suspect a powered hub that may not be powered

I had a similar problem but if I turn on my midi keyboards first and then launch Sonar they are there for me to assign...

Thank you all for the advice. I would have replied sooner but I don't have internet at my house and have to go to the library. My sound card is the M-Audio Delta1010. I don't have a USB hub. I'm using the ports that are connected to the motherboard. I'm using WDM, not the ASIO. I tried the MME and that just created more problems. It seems like the PocketPod has the most trouble connecting. I didn't see any updated drivers on the Vyzex site.

Ah, you didn't mention the Delta 1010 in your OP. So that is a total of FIVE usb devices. I would follows Jims advice and try your 1010 and nothing else for some torture tests and see if it plays OK. then try adding devices.

 I was going to say You should  the Line 6 Gear Monkey Monkey and let it update yoor Pod drivers, but you have no internet at your house so  i suppose you have to D/L drivers elsewhere and bring them home ..

I would suggest ASIO
