My device does not show as connected to my computer

If your computer is not showing the device, means it doesn't recognizes the it exists. Check connection of your device to computer and check if your device is powered on. By the way you never said what is ths deice troubling you.

Download the driver from Verbatims web site. Reinstall it some of thos flash drives are really picky. You might have had a virus and it wrecked the connection. Reinstall the driver from Verbatim.

Could be that the control board inside the device is going bad. Have you tried other cables to connect to your computer?
If that fails, then I'd suggest removing the drive from it's enclosure and using an adapter to connect the drive directly to your PC as an external device. I found one on eBay, years ago, for about $13USD.

YOU SHOULD UP DATE YOUR USB DRIVER.RIGHT CLICK ON MY COMPUTER .SELECT DEVICE MANAGER AND SEE IF THE DEVICE CONNECTED IS WORKING PROPERLY

Try and reset the player.
Reset the player:
1. Slide and hold the Power switch up for approximately 20 seconds.
2. Release the Power switch.
3. To turn the player on, slide the Power switch up then release instantly.

Then try this
Connect the player to your computer.
The screen on your player should turn on, show 'Connected' and indicate the battery charging or full.
- If the player does not turn on try other USB ports or on another computer if one is available. Make sure you are connecting directly to the computer USB port and not to a USB hub.
- If there is nothing showing on the screen and the player does show up in as a storage device in an explorer window, then the players screen is just not working.

If you receive the error "USB Device Not Recognized" on the computer, the player is most likely failed. Additional troubleshooting is unlikely to correct the problem.

The Sansa player will show up on Device Manager's right pane as:
1. USB Mass Storage device (if the player is set to MSC)

If there is a yellow exclamation point (!) or question mark (?) beside the device, try to refresh the drivers.
Refresh the drivers
1. Right-click the entry with the error mark, select Uninstall.
2. On the top menu, click Action then select Scan for hardware changes.

NOTE: If a device with yellow exclamation point (!) continually appears and disappears, then the player is most likely failed. Additional troubleshooting is unlikely to correct the problem.

Connect using MSC mode

Hi, When the BlackBerry device is connected by Universal Serial Bus (USB) cable to the computer, it is not detected as a BlackBerry Device on the Windows Device Manager. Universal Serial Bus controllers does not show any BlackBerry device, even though it has already been connected to the computer.
It is because Blackberry Desktop Manager drivers are not registering with the Windows operating system.
To resolve this issue,
1) Uninstall and reinstall the BlackBerry Desktop Manager.
2) Connect the BlackBerry device to another desktop computer to determine if the issue could be related to USB port hardware.
3) Update the BlackBerry device drivers manually.
I hope this information will help you.

Device Manager displays only non-Plug and Play devices, drivers, and printers when you click Show hidden devices on the View menu.
