You may need to check with your ITadministrator to see if this is causing the problem.SOLUTION 2 -
Refresh the driverSTEP 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 anothercomputer if one is readily available. Ensure you are connectingdirectly to the computer USB port and not to a USB hub.
- If there is nothing showing on the screen and the player does show upin as a storage device in an explorer window, then the screen is justnot 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 canconnect to your computer in MSC or MTP mode. Exceptions are SansaConnect and Sansa Express which only use MTP mode. MTP mode is therecommended and default method for Sansa Players when used with WindowsOS. 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 yellowexclamation point (!) continually appears and disappears, then theplayer is most likely failed. Additional troubleshooting is unlikely tocorrect the problem.SOLUTION 3 -
Connect using MSC mode
Connecting in MSC mode will help determine if there is a problem withMTP mode or with the Auto Detect mode feature of the player. You canuse Forced MSC mode or switch the player settings to MSC.
Instructions to connect in Forced MSC mode are listed here:http://kb.sandisk.com/app/answers/detail/a_id/61
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 firmwareNOTE: Sansa Express and SansaConnect do not have MSC mode. For Sansa Connect you can tryreinstalling the firmware using the Connect Recovery Mode.Additional troubleshooting notes:
If you have replaced the Sansa Player and you still have problemsgetting it to recognize in the computer, then you may need to try someadditional 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 Kit
