Hi
I'm using a axiom 49 keyboard on my windows pc, and when
i power it up, sometimes windows tells me "usb devices not recognized", then
i leave it powered until windows recognizes it, but after some usage the keyboard drops again and i lose the control on live.

A signal: the screen flashes, like the device is having a power instability...

PS. sometimes it works like a charm, it's a very random thing.
PPS. i tried everything said on m-audio support.

Thanks in advance.

Is there enough power going to your USB devices? That's all I can think of... maybe hookup a wall wart to power the keyboard or use a powered usb hub.

It definitely could be a power issue. I had bad luck with a usb hub initially, even with it plugged in (powered hub). Once I plugged it directly into the computer, no problem.

However while it seems to be working fine, I have also started getting the blinking screen. It even went blank-blue on me once! Fiddling with the usb cable seems to help, but it might just be my imagination. We'll see... Other than that and the pads not retaining their new numbers (for Impulse), it seems to be working correctly.

But it's always something with M-Audio stuff....

Try a different USB cable. If jiggling the jack makes a difference the jack may be loose/broken, crack it open and add some solder to the connection.

Thank you for your answers guys, i'm getting a power supply to see if things
get better.

hehe really, it's always something with M-AUDIO stuff
