I didn't think the Axiom 49 (I have one) needed drivers.  My old Oxygen 8 does not show as Oxygen 8 in device manage but something different with the word legacy in it.  
 If you have another DAW you could see if it shows up.  My Oxygen 8 shows up in Reason but it wont let me use my EWX2496 in ASIO unless I use ASIO4ALL.
 My solution to using M-Audio products is to not buy their stuff again. Nothing but poor driver support.

While we're here, I have one other issue. Every time I open Sonar, I get the error message below. It seems to be inconsequential, but it's just annoying.
 
Runtime Error!
Program: ...\SONARART.exe
R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
 
Any advice on that one?

The problem seems to be that the manifest for your installation of Sonar Artist is absent, defective or inaccessible. You could try re-installing Sonar Artist using the administrator option which might solve the problem if  access to the program's manifest is limited by a permissions issue. Right click the installer application exe file and choose "run as administrator" in the dropdown menu. Or before trying that, see if you can run Sonar as administrator and avoid the issue. It may well be inconsequential, and the best advice on this one would be from "the application's support team."

Interesting. What type of file is a manifest? Is it one of those .dll files?

Really???

 Just contact Sonar support if this is an issue.

What, were you shocked that I didn't know what a manifest is? Lol...that's not exactly common knowledge.

Actually surprised that you wanted to pursue that rather arcane line of enquiry. Waaay more than I would attempt. Good luck.
