does this device work while connected to a usb jack?

Yes. I usually have it plugged into my laptop, but I've also plugged it into the USB jack in my car and also into a USB wall adapter.

Yeah, I see now - I have the X2 which does - apologies - hopefully, it works with the usb plugged in - if not, move up. Best - js

The device operates from a USB port on your computer. It adds the phone jack that is missing on modern computers. I think the answer is "no".

I have used this device with my desktop and car stereo only,,, any device which has a USB port.

Good question, dont remember if it actually does. I pretty much use it via USB power.

Yes, I purchased the same one and it works perfectly. When plugged in, the MP3 will turn on automatically and the computer will find USB drivers. You might have hidden adware, spyware and or virus(s). try a good cleaning of your computer first. It is possible the cable is bad but mine works perfecly. Good Luck!

Yes, it just plugs into the USB port. I would not recommend it, though, mine only worked for about two weeks.

YES. I specifically bought this so that I could charge while using line-output to speakers. So yes, it will charge and function simultaneously while connected to usb power.

Kerwin, the answer to your question is yes. I started playing my usb and then unplugged the unit. When I plugged it back in, it started playing again on it's own with out me doing anything. PS Be sure to move the selector knob to usb. Just tried it and if you don't move the selector knob the usb just flashes and doesn't play. So move the knob to usb. This happens to be a great little unit. :)

I honestly can't see any reason this will not work on any device with a USB input slot, but every manufacturer of products could potentially block it's use. I have not had any issues with that yet. Please Note one thing I forgot to mention, our aspect of on and off seem to be opposite from either the manufacturer or me. When I think it is on it is really off, but just watch the red optical light for acknowledgement it is on, but that has no bearing in using the product. I still recommend it.

Seems to work well when connected to a regular USB port. So far I have not confirmed that any of the USB ports I have used are USB2. I apologize for that. Good luck with finding a definate answer.

NO! and it's one of the things I love about it. You just plug into the USB port and you're good to go!!

Yes, but not for long. Mine is now scrapped because of the failed USB port and I tried everything to fix it...

This should as long as your USB is working. I wouldn't use it in an application that needs to be removed often as the audio jacks are not robust. But if the plan is to install it and leave it plugged in you should be fine.

I believe it only converts from analog to USB connected device. I don't think it goes the other way, but I'm not sure. Sorry I couldn't be more help.

No-- the device essentially turns a single usb port into a multi function peripheral that is feeds the appropriate signal back into the primary cpu. It has its own power supply and remains on even when computer is powered down.
