You should be able to buy an external USB drive (or thumb drive) at any electronics store.
You can connect a USB hard disk drive or USB
memory stick to your TV by using the USB inputs of
the TV. This feature allows you to play files stored in
a USB drive. 2.5" and 3.5" inch (hdd with external
power supply) external hard disk drives are supported.
IMPORTANT! You should back up your files before
making any connections to the TV set in order to
avoid any possible data loss. Manufacturer will not
be responsible for any file damage or data loss. It is
possible that certain types of USB devices (e.g. MP3
Players) or USB hard disk drives/memory sticks may
not be compatible with this TV.
Quickly plugging and unplugging USB devices, is a
very hazardous operation. Do not repeatedly quickly
plug and unplug the drive. This may cause physical
damage to the USB player and USB device itself. Do
not pull out USB module while playing a file.
Media Browser Menu
You can play photo, music, and movie files stored
on a USB disk by connecting it to your TV and using
the Media Browser screen. To do this, perform the
following: Connect a USB disk to one of the USB
inputs located on the side of the TV.
You can connect two USB devices to your TV. If both
USB devices include music, picture or video files, USB
selection OSD will be displayed on the screen. The
first USB device connected to the TV will be named
as USB Drive1. Select a device by using up or down arrows
and press OK

Try NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo management program.

1.plug it on your pc. ..

yes your pendrive is attactked by a severe virus.......you need format it you can do only one thing click on format option or restart the pc then press f8 thenan stat windows setup when you reach the formatting option then only format that pendrive.............

Which "disk utilities" did you use?
Ones that check the "file-system-integrity" (that every file on the disk is listed in the table-of-contents, and that no 2 files point to the same block on the disk)?
Ones that write data to every block on the disk, and read the data back, to confirm that the disk can _correctly_ store data ?

What computer? Desktop? Laptop?

How much voltage/amperage does each USB port supply to the connected USB device?

Are you connecting the devices to a USB hub, or directly to your computer?

Do the external disk-drives each have their own power-supply?

Step 1: Connect your hard drive to your PC.
Step 2: Create a FAT32 partition on your hard drive. If you’re using less than 32 GB, you can use Windows via “Control panel > Administrative tools > Computer Management”. If you’re using more than 32 GB, you’ll have to use an external program, e.g. Partition Magic.
Step 3: Load all the content you want from your PC onto the external drive. This should consist of files that can be read on the Xbox hard drive.
Step 4: Remove the external hard drive from your PC. Plug it into your Xbox 360 console through the USB port.
Step 5: Go to the Media menu on your Xbox screen. Select "Portable Device" from the menu. All the readable files saved on the external drive should be available to read on your Xbox 360.
N.B. Xbox's connection with an external drive is read-only. You can only read files that are already on the drive after connecting. You can't save game files or anything else on the Xbox main drive onto the external hard drive. Also, USB storage devices cannot be used for Xbox live marketplace content.

I'll assume first that you have wav files on your PC that you'd like to import into your 2488 to use as percussion tracks.

You'll have to convert those files on the PC first into mono wav files. The 2488 can handle 16 or 24 bit so the bitrate shouldn't really be a problem. (It will also automatically truncate a larger bitrate down, but you should really dither the files rather than let them truncate... another topic).

You can use Audacity (free) to convert stereo wav files to mono wav (audacity will also dither for you).

Once your files are converted and saved on the PC, on the 2488 open the USB connection from the DISK menu. (This assumes you already have a usb cable connected between your PC and your 2488.) You will see a device appear on your filelist called HD_2488 or something like that with a drive letter. Copy your mono wav files into the WAV directory on the 2488 USB device.
Then on the 2488 press 'exit' to close the USB and from the WAV IN/OUT menu choose 'USB import'. You should see the WAV files listed. If those files are not mono waves you won't even see them listed. Select the file(s) and press enter to import. You'll be prompted to choose which track to import them to.

That's pretty much it.

The USB port is to be used with USB mass storage devices like flash drives, thumbdrive or external hard drives. The IPod's USB connection is not seen as a mass storage device it is proprietary. You need the iPod connection kit, part number KS-PD100 to connect your iPod to the deck.

I had the same problem trying to transfer pics from my camera. The error message is "The Device is not Ready." I got mad when I read the "solution" from the "plumber" that said to read the directions. DUH!. Now for the real solution... and reading the directions won't help. Your PC is trying to find the camera connected to a specific drive. In my case it was the "E" drive which was already in use, mapped to a shared drive. Once I disconnected that drive it fixed my problem. To disconnect, highlight the drive, go to Tools and Disconnect Network Drive. Reboot the PC and plug the camera in before booting back up. (If you have hardware connected to the drive, right mouse click on the drive and eject.)
