NOTE: MAC computers do NOT support MTP modes of USB conectivity in a MP player. A Sansa player in MTP mode when plugged into a MAC computer will NOT be detected or recognized. MAC computers supports Sansa players in MSC mode Sansa players can only be recognized by a MAC if the USB mode on the Sansa player is set to Auto Detect or MSC.
Check in the System Profiler Open System Profiler from the Utilities folder, which is inside the Applications folder. From the Contents column on the left, under the Hardware header, select USB; the panel to the right will show all the USB devices that the computer recognizes. It may not identify them correctly by name, but it should have the right number of devices listed. . Navigate to USB Mode settings. Sansa View - From the Main Menu, select More > Settings/Options > System Settings > USB Mode.
Sansa Fuze and Sansa Clip+ - From the Main Menu, select Settings > System Settings > USB Mode.
Sansa Clip, e200v1 series, e200v2 series and e200R - From the Main Menu, select Settings > USB Mode.
2. Select Auto Detect, MTP or MSC. e200R - PlayforSure is MTP and Rhapsody is MSC

I also had the Sansa Clip, to swicth to MSC setting, in sansa clip player, go to seting > USB mode > There's 3 option:
1. Auto detect
2. MSC
3. MTP

Select MSC, it would be normally detected in any computer, if not, try to format your player :)

do u have windows or mac system? if mac,
Although MAC OS is NOT a supported operating system, the Sansa player can still be recognized if the Sansa player is only plugged in MSC mode.

Because you are not including any system information about your computer or history of this problem I am only taking my best stab at this because I had the same issue at one time.


Make sure your M240 is not connected to the computer. Then go into the "settings" menu and then go to the "usb" part. Then Select "MSC" from the menu, instead of "Auto Select (or something similar). If MSC is already selected try changing to the other setting instead.

Then turn off your player and connect it to the Win XP computer and it will be fully recognized and you can then go to My Computer and see it there and use it. It also at this point should be recognized by WMP.

If you mean that the songs don't show up on the computer screen, then you probably need to change the USB MODE setting on the Clip. To do this, disconnect the Clip from the computer, then scroll to SETTINGS. Select Settings, then scroll to USB Mode and select it.. (If your Clip is very old it might not have a USB Mode listed under SETTINGS. If this is the case you should update your Clip's Firmware from the sansa website). Older computers recognize the MSC Mode while newer ones should recognize either mode. (except XP Professional doesn't seem to recognize the MTP mode). Songs entered in one mode won't show up on the computer if you're in the other mode. If you mean that the songs aren't showing up on the Clip's own screen then this solution probably won't help. By the way, I've never had any luck with the "auto detect" mode.

Make sure USB mode is MSC....If this doesn't work make sure that you are connected to a 2.0 USB port....I had to install the update on to my labtop and finally it recognized it and updated....
Download Update if you haven't yet(http://mp3support.sandisk.com/sansa/Installer/1082/SansaUpdaterInstall.exe)
Then connect to your computer and see if it works
Hope it does..........Please rate

There are two connection settings in USB: MTP and MSC. For some reason MTP is the default, but it doesn't connect properly on all computers. Select MSC and plug the player in again, the computer will recognize sansa e250 but not show the driver just yet. It is installing recognition software (just basic drivers - nothing heavy) and it doesnt tell you what its doing until its complete. WAIT FOR IT. Once it is complete you will see both the sansa e250 and the removable memory slot in your "my computer" now you're good to go.

Make sure player's usb menu is set to MSC, so computer will recognize it. Not sure why, but sometimes it helps to try another usb port on the computer. Good luck.

Hi there , in the settings menu in your player if you go into usb you can change it to msc mode and it will read as a normal usb drive so you can transfer songs etc

I agree with the above suggestion. Try setting the USB Mode under "Settings" on "MSC" on the Sansa. My computer would not recognize the e260 when the mode was set to "MTP"; works fine on "MSC".
