Hi, I had a problem many people complain about and few get answered. My Pocket POD worked perfectly on my desktop, but on the laptop it did not. Every time I connected the USB to any laptop port the POD worked for a few seconds to a minute, then suddenly shutdown and rebooted. I tweaked USB power settings, I changed out multiple USB cables. I moved to different ports. Sometimes everything seemed to be resolved only to have it do a sudden reboot once again. By chance while googling various phrases to find a solution I randomly discovered that a wireless mouse may be interfering with MIDI. I changed my wireless mouse to a wired mouse and the problem was solved.
