This may be caused by one of the following:
1. Minimum system requirements were not met.
2. Corrupted drivers.
3. Computer restrictions.
4. Power issue.
To resolve this issue, try the following solutions:
SOLUTION 1 - For brand new player or first time connecting to this computer.
For Windows XP users: verify the following operating system requirements are met.
- Windows XP SP2 or higher
- Windows Media Player 10 or higher
Download and install the latest
Windows Media Player if it's not installed.
For Windows Vista users: If the player is seen in My Computer when using MTP mode, but not showing in Windows Media Player.
- Download the hotfix from
http://support.microsoft.com/kb/939211.
- Run the hotfix.
For MAC users, see
Sansa player not recognized by a MAC OS
NOTE: If you are trying to connect
to a Computer at work that is part of a network, there may be user
right restrictions that are set to disable access to new hardware or
stop any program installations. You may need to check with your IT
administrator to see if this is causing the problem.
SOLUTION 2 - Refresh the driver
STEP 1 - Connect the Sansa player to the PC
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 readily available. Ensure 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 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.
.
STEP 2 - Check under Device Manager
1. Right-click
My Computer, and select
Manage.
2. Click
Device Manager on the left pane.
NOTE: Sansa MP3 Players can
connect to your computer in MSC or MTP mode. Exceptions are Sansa
Connect and Sansa Express which only use MTP mode. MTP mode is the
recommended and default method for Sansa Players when used with Windows
OS.
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)
2. Portable Device (if the player is set to MTP mode)
If there is a yellow exclamation point (!) or question mark (?) beside the device, try to refresh the drivers.
STEP 3 - 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.
SOLUTION 3 - Connect using MSC mode
Connecting in MSC mode will help determine if there is a problem with
MTP mode or with the Auto Detect mode feature of the player. You can
use Forced MSC mode or switch the player settings to MSC.
Instructions to connect in Forced MSC mode are listed here:

Instructions to switch player to MSC mode are listed here:
http://kb.sandisk.com/app/answers/detail/a_id/207
If the player is detected in MSC mode but not when set to MTP mode, try to update or reinstall the Sansa firmware
NOTE: Sansa Express and Sansa
Connect do not have MSC mode. For Sansa Connect you can try
reinstalling the firmware using the Connect Recovery Mode.
Additional troubleshooting notes:
If you have replaced the Sansa Player and you still have problems
getting it to recognize in the computer, then you may need to try some
additional troubleshooting.
- Try connecting on another computer.
- Try using a different USB cable
- Try connecting to the back USB ports which may supply better power.
- If only MTP mode is not working, try reinstalling Windows Media Player
For Windows XP try also
download and install the MTP Porting Kitfor more answers at:
