New USB mixer

I just bought a USB mixer. Not because it was USB, but because my other one was flaky. I was told about this USB feature at the store, and don't know how to get Sonar to see it. I've plugged the cable in, and Windows used that ASIO4ALL driver, but when I started Sonar, I expected it to detect a new input, and when it didn't, I then expected a new input option to be available for a track, but I don't see anything. I poked around the Properties window, but am at a loss. Also rebooted the PC to see if that would help.
 
Like I said, I didn't buy this because it was USB, and am currently fine using my regular M-Audio sound card, but I was told the USB connection might reduce noise, plus I'm just curious if I can use it.

Possibly your installation of ASIO4ALL is masking the ASIO driver of the new unit. What model is your new unit?
 
Meanwhile, if you already have another device configured to use ASIO4ALL, you may need to go into the config dialog of ASIO4ALL to choose your new device. Sonar won't see that choice.

Sorry everyone, duhh... It's a Behringer Xenyx Q802
(who comes up with these names?)

I don't really care which one I use. I only need one stereo input anyway. I really just wanted to try out the USB to see if it was better or easier or anything. 
 
I tried plugging in the USB and Sonar popped up a message saying there was a new input and asking me if I should install it. I said Yes, but in my track inputs and the Properties page, things look the same. The Windows hardware page indicates a new input, namely USB Audio CODEC, which I set as the default. But nothing in Sonar says anything about USB. The only inputs still say M-Audio Delta ASIO etc.
 
I was just about to unplug the RCA from the M-Audio card to see if it is maybe recording into USB anyway, but I realized there's another complication I'm confused about:
 
As mentioned, my sound card only has the single stereo in, which is really fine for my needs. However, it means I need to use the Effects send to record anything to the computer while still hearing everything else. So my mixer's effects send goes to the PC input on the sound card. (The sound card's output goes to the tape in on the mixer for monitor purposes.) When I want to record a vocal, or bounce down a Midi track, I just bring up the effect volume knob for that channel and make sure everything else is 0. Works fine. (If I need to record a stereo Midi track, or my digital piano, I repatch a bit to record the stereo, since the FX send is mono).  So if I switch to the USB, don't I lose the ability to record into the PC on one channel and simultaneously monitor the others?

Take it back and get the 802 without USB. 

There's no need for asio4all if you audio interfaces already have proper asio drivers. And as I said you can use 2 devices if you swicth to WDM mode , this is really what asio4all is doing anyway. ,
Asio4all can cause many issues once installed and it's not that simple to 100% remove it. 
 

Guys - Behringer has started providing ASIO4ALL instead of proper drivers ...

in ASIO 
 
LEFT INPUT 1/2
RIGHT INPUT 1/2
STEREO INPUT 1/2
 
that's the nomenclature it uses.
 
again, tho, as I said above; the delta and the berhinger will have TWO DIFFERENT CLOCKS.  if you try to use them in the same project, regardless of using WDM driver mode or not, you WILL have timing drift between the tracks.

You should still use ASIO mode whenever it is available. I only mentioned WDM mode if you were going to try and use both interfaces to record. ASIO only allows one device. WDM mode is more forgiving but does come with pitfalls. 
In loopback testing I found WDM mode was out of sync. So I don't recommend it for overdubing at all. It will work fine for the live recording because syncing tracks is not involved unless you are using 2 devices. 
  
As that's a good point about the 2 devices possibly not syncing. I have yet to use my Yamaha for a full recording in tandem with my us1641.  I just set them both up and tested a short piece in Sonar to see if it would work. Both the Tascams  inputs and the Yamaha ( marked as Steinberg ) show on the inputs list in Sonar. I'm foggy but I do seem to remember the Tascams SPDIF do not show in WDM mode.... 
 
I leave everything in ASIO mode and it seems to not cause any issues with Sonar running and the Yamaha playing back music from Windows. Note I am staying in 44.1/ 16 which might make a difference. 
 
I have recorded straight stereo from the Yamaha mixer to Wave Lab and Sound Forge and that is fine too. I get no hums or issues. But somehow it doesn't suprise me that a Berhinger would hum. It really sucks that they are not taking the trouble to supply drivers. The USB connection is therefore pointless. Take it back and buy a Yamaha, Mackie or A&H.

Sorry to be obtuse, but what do you mean by "use"? I am using the behringer as my mixer, and its effect send is going into the sound card. the sound card's out is going to the tape in on the behringer, for monitor purposes. I am not using the USB at all now.

If you are not using the USB part of the mixer then it won't be a problem.  the clock timing issues will occur only when you're trying to use two soundcards.  the USB device for the mixer and the delta both are soundcards.
