I just bought the Razer Megalodons and I've run in to a problem. I cannot transmit while playing audio. I also keep getting "USB bandwidth exceeded" errors. I'm using a 850W power supply and I used to be able to transmit and receive audio simultaneously in the past using a USB headset.

I'm using Windows 7 64 bit for gaming, and my headphones are plugged into a USB 2.0 port.

I've discovered that I can transmit/receive if I plug my G15 keyboard into the USB hub that is part of my monitor, and keep the headphones plugged into the USB ports on the motherboard.

    The "headphones suggestion" part of your question(and the comment) is very subjective and borders on a shopping recommendation, which is considered off-topic here; I would recommend removing that question and sticking with troubleshooting the Megalodon. Also, as a future tip, multiple questions should be asked as, well, multiple questions, as opposed to sticking them under one header. Please read the FAQ.

  • Alright, I edited the post to remove anything not pertaining to troubleshooting these headphones. Sorry about that.

  • Try updating the firmware on them, and see if that helps: razersupport.com/…

(Answer as described by OP in comments)

The headphones (and other peripherals) appear to be drawing too much power from the USB hub, so you need to find some way to split peripherals across powered hubs. Using the USB ports on a monitor should work, as should adding a card that contains more USB ports.
