Hi,

  This issue could be related to a number of things. First check your connections.

  Have you tried connecting to different USB Ports?

  Are you using a USB hub?

  Make sure you have the latest drivers installed:

Hey Deathwalker,

  If it used to work on the same laptop and now it doesn't, something must of changed on the laptop. Did you apply any software or hardware updates to your computer around the time you started to experience this?

  Another thing to check on is your Windows power saving options. If this happens to you while running on battery power it is possible that there is USB power saving option enabled that is limiting USB bandwidth, try and disable this setting to see if it helps.

  You also mentioned that there was an issue with 2 out of the 3 USB cables you tried, you might want to try getting a new to eliminate the possibility of it being related to the cable itself. I would also suggest to retry the connection to the additional laptop using the new USB and all available USB ports to help determine if the problem is related to the computer's USB connection or the POD HD500 hardware.

  Thanks.
