My NEC MP900 won't sync!

I've tried everything, tried to find a solution in other forums etc. I'm beginning to think the usb port doesn't work. I bought this on ebay and have never been able to sync it. I don't get any communication between the device and activesync (3.8). Any help will be greatly appreciated!

Re: My NEC MP900 won't sync!

First when you plug it with your PC.. do you hear the sound of the connection ? ... can you see the USB Icon at the system tray? Doest the system pop-up a message saying that the USB device isn't recognized? If it doesn't ! then there is no USB connection made... Try live support.. it's better to solve problems.

Window Vista syncronizing with iPAQ 3835 problem

In order to sync any iPAQ with Windows Vista, you will need to download and install Windows Mobile Device Center 6.1 from

Activesync will only work for XP Operating Systems and earlier.
  • To find out whether your version of Windows Vista or Windows 7 is 32-bit or 64-bit, click Start, right-click Computer, and then click Properties. The version is listed after System Type.
  • You can use Windows Mobile Device Center 6.1 only with phones running Windows Mobile 2003 or later. ActiveSync and Windows Mobile Device Center won’t work with Windows Embedded CE 4.2 or 5.0, Pocket PC 2002, or Smartphone 2002 devices. (To see which Windows Mobile operating system you’re using, and if your phone doesn’t have a touch screen, click Start > Settings > About. If your phone has a touch screen, click Start > Settings > System tab > About.) To sync content to any of these devices, you must use a USB or serial cable and your computer’s Internet connection and File Explorer.
  • You must use Microsoft Outlook 2002, Outlook 2003, or Office Outlook 2007 to sync your e-mail, contacts, tasks, and notes from your computer.
  • You must use a USB cable to connect your phone to your computer the first time you use Windows Mobile Device Center to sync.

Getting connected

What kind of Drivers? USB sync Drivers or Orinco Wi-fi Drivers? Try here for USB to Computer Drivers if you have Windows XP: The full CD contents that come with the Mobilepro can also be downloaded from the same page. For Wi-fi Drivers, I THINK the Agere Wi-fi Drivers will work, although I may be mistaken. Try them Here:
And any MiniUSB cable will work with the Mobilepro

USB Sync Cable

I dont' think so. No other PDA does - it would be quite a drain on the USB port. It isn't like powering the tiny LED in an optical mouse.
