REG - windows not recognised

I get the following message after connecting the SANSA EXPRESS to my PC. "USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."

For some models pressing select and the + volume button for 10 sec resets the device and it is recognized by the pc on connecting. Check ur manual to check the way to reset ur device. You can download the manual from http://www.sandisk.com in case you have misplaced it. Drop me a mail at [email protected] to let me know if the solution worked for you.

On the SanDisk Sansa Exprss 1GB, I found the only thing tht works is when you disconect the devise from the USB, hold the volume+ and both squares by the screen aka the selecttion and the silver solid square all at the same time. so you're holding down 3 buttons at one time, volume+, thumb presses both main squares at the same time. then recharge into USB.

Had this problem too. If you are using one of the front mounted USB ports on your case try using one of the rear ones that are mounted direct to the motherboard. I recently built a new system with a Coolermaster case and found the case mounted USB gave this problem. No idea why as everything else I plug in there works fine. Fortunately my monitor has a couple of USB ports so I don't have to grope around behind the case.

My sansa clip (blue) does not charge when I connect it to the usb port on my computer. I've tried resetting it and using other cables but it still does not accept a charge. The computer does not recognize...

Why is my Sansa player not being detected by my computer when I connect it?

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.
Image
2. Click Device Manager on the left pane.
Image

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.

MY Sansa Express, says USB malfunctioned, when connecting to PC

These are the most common methods for recovering Sandisk's Sansa Mp3 Players. I have been almost universally successful in recovering Sansa players using one or a combination of these methods. These methods do not work if you are having synchronization or music format issues - they are for recovering a player that will not power up, freezes, flashes, is not recognized by the computer, and a host of other issues.

Reset the Sansa Player first. On most models, restart is done by holding the power button in for 15 seconds or longer. Check your specific manual to be sure. The manuals are available from the Sansa website if they have been misplaced.
Download the Sansa Recovery Tool from the Sansa website.
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/DriverDownload/driverList.asp
If these fail, then:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
If you get the problem where MTP Device keeps popping up continuously, uninstall the "MTP Device" by going to Start à Control Panel àSystem à Hardware à Device Manager (you computer may vary slightly, depending on Windows Version).
You may have to restart your computer after each of these methods to get them to work properly. Disconnect your Sansa player BEFORE shutting down your computer.
