USB Mode I just bought a Sansa e250. It tells me to switch to MTP Mode. It says to go to Settings/USB Mode. My player does not have USB Mode anywhere in the menu. I went to the store and looked at one, and sure enough, it had USB Mode under Settings-mine does not! How do I get that setting? Help!

Hope this helps. See the section about the hot fix first----- If you are using Windows XP: you need the following. Windows XP SP2 or higher Windows Media Player 10 or higher Download and install the latest Windows Media Player if it's not installed. If you are using Windows Vista: 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. Refresh the players driver 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. 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. 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 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: 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 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 Kit ......

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.

For a more detailed explanation of MSC and MTP modes see my tip posted here --- -> http://www.fixya.com/support/r3774047-solve_mp3_player_connection_problem <-

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.

I jumped the gun on my earlier advice - the format function was not on this particular Sansa. Go to the Settings Menu of the Sansa and change the USB Mode to MSC mode or MTP mode - whichever one it is on now, change it.

Go intothe Settings menu of the Sansa and change USB Mode from MTP mode to MSC mode or vice versa

switch to mtp mode or auto in the menu - read your manual for details, and see if you have better luck

SETTING USB MODE
1. Select Settings menu in Main Menu.
2. Select USB
3. You can select AutoDetect or MSC mode.
Note: AutoDetect will default to MTP mode. The MTP mode supports Windows Media Player 10 only.
You must use the MTP mode to synchronize music files using Windows Media Player 10 for the optimal
system performance.

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

You're pretty much screwed that way because the way to change the USB mode on the device is actually in the mp3 player's firmware, you'd have to navigate to the settings and somehow make your way to the USB setting. Sorry about your luck.
