Hi, Are you getting a "USB device not recognized" error whenever you plug in a USB mouse, keyboard, or other USB device? I love USB and have 5 ports on my computer so that I can connect my mouse, keyboard, camera, phone, and printer to it all at once!
However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!

So I started with the normal fixing methods, including uninstalling the drivers for my devices and reinstalling them. That didn't work! Next I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That didn't work!
I read online that in order to fix this problem I should go to Device Manager and uninstall all of the devices under USB Controllers. Restarted the computer, reinstalled the USB drivers, but the problem STILL did not go away!
You may also see in Device Manager that the device shows up as an "Unknown Device".

So how did I finally fix the problem? Well, apparently it's a super simple solution! No need to edit the registry, uninstall drivers, or anything of that sort.
Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that's it! Note that this does not mean just turning off your computer because modern computers don't really turn off when you press the power button as the motherboard still gets power.
First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be "rebooted" also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!
So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.
Hope this helps someone fix that pesky "USB device not recognized" Windows error!
-Check all connections (Ethernet, Power, USB, etc) -Install the appropriate driver for the device, usually included on a CD -Double Check compatibility with your system (system requirements usually on packaging of product) -If you haven't rebooted since you set it up, then reboot, this fixes a lot of things -Try the product on another computer -Try different cables/ports on the comptuer.
If nothing works, then send it in if it's under warranty or contact a professional service.
Did you try another USB drive? Only MP3 and WMA are compatible. No partitions, no data security, etc. Check page 20 of the instruction book. If you don't have it, then go to books.jvc.com and download the instruction book.
you have to keep the usb plugged into the same one you had it in before than shut your computer down than turn it back on and click install now wizard that should help you...
Make sure the audiobook is in the correct format, and that it has transfer rights.
This is the worst mp3 player ever invented - i have to tell you this up front. There is no driver, the company does not support the product anymore - I would return it now while you still can.
Either the device is bad, the pc port is bad, or the software is faulty. Try connecting to different usb port, then a usb port on a different pc with a compatible os. If still not recognized, then there is physical damage to player.
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
should have at least windows 2000 sp4 or xp sp1 as operating system. plug into usb port on computer while computer is turned on. computer should recognize and install it as mass storage usb device and assign it a drive letter. sometimes xp will recognize it as a panasonic mtp device. this doesn't matter, you can still drag and drop files on it through windows explorer file manager.
