How is the signal grounding handled? Is it brought out through the USB and PC power ground? Are there any issues with grounding?

I am not sure how the grounding is connected. I would ask Velleman. However, I would think the USB grounding was connected to the PC's power cord grounding.

I only use a FireWire cable from my PC for power. Mine works fine that way.

Rickk, there is a USB dongle you plug into your computer that provides a communication interface. The setup for this is very simple, just plug in, power up, press the connection button and done.

Grounding in not necessary. If no dedicated phone inputs, just connect to any vacant input (game, aux, etc)

What method have you been using to charge it? Usb to pc or usb to power adapter? Also, have you tried using a different cable? I would try holding the power button down a bit longer than usual just to see if it eventually comes on. Hoping it fires back up for ya!

As with the prior response, mine has a "regular" grounded plug on the end of a fairly long cable. Am very pleased with the unit. Hope this helps.

The cable man told me that (but theirs is down the street) and I put this on anyway; his signal device said it didn't ruin my signal so he could leave it on (after I made him check it.) I lost a cable modem and a router nic after a storm with their protection so I put this device on hoping it would do more. YOU MUST ground it, that is how it works. if just a few feet a way you have the shielding grounded then I'd think you wouldn't need it but I'm not an electronics expert so I can't say definitively. Edit: I looked into the matter and the device can't fully function as well without being grounded from the sound of it; my friend thought it would do something but not much without being grounded itself.

Thanks for the feedback. I've found that I can use other USB cables on other PC's even if they don't have the Creative Centrale software installed, so that's the good news. The Ac adaptors with the same kind of USB connector have not worked. So looks like I need to buy the zen Ac adaptor. It should at least allow me to listen and charge at the same time <grin>

I'm using my USB connection to successfully power mine. I have not encountered any issues with this.

I've never had this issue. The only time I had any connection issues is when I was connected to a surge protector. After plugging directly to the wall socket, the issue went away.

Drear Lorain, This will eliminate ground loop problems with your cable modem but are your modem's ups and downs caused by a ground loop? Not very likely. Ground loop noise is at low frequencies - mostly 60 Hertz and might reach as high as 1 MHz. Cable modems operate above 5 MHz thus what you are experiencing is most likely interference, such as noise coming from other cable modems that share your line. Another cause of ups and downs is a faulty connection or faulty cable amplifier and the best solution is to call the cable company to test the line. If you still want to try this isolator it won't hurt and there's a small chance it will work for you. Eli

These are UB3 adapters. My laptop has only USB2. But the adapter worked and worked well. I experience no problems with signal quality. The two I purchased have rather stiff cables with them, this may or may not be important but the cable certainly are awkward in use.

As I remember the device gets its power from the PC through the USB cable. I had to use a USB extension cable and found that with the extension cable the PC supplied power wasn't sufficient so I used the power supply from my old Plantronics headset. Other than that it works great. Very pleased.

I ended up throwing that one away because I needed one that sent a signal to the receiver from the computer and it does not do that. It seems to work only from a component to the computer but not out of the computer. Hope that helps.

OK I see there are 2 USB headers on my motherboard. Do I have to ground any wires or anything?

Tripp Lite tech support is great. it is grounded. I have this exact unit and use it as a backup to my Xantrax

I have not had any trouble except changing the battery. As soon as I put the usb port in my computer.I was ready to go.I hope you find the out the issue soon.
