Hi folks: My first time on this forum.
Just received my brand-new N900 yesterday. It is intended to replace my Palm TX as well as my cell phone.
I installed Nokia PC Suite - v 7.1.40.1 (the latest, I hope).
I have the phone connected to my computer (Windows XP) with a USB cable.
I get the following error messages:
Nokia N900 USB connection in a non-compatible USB mode Or
Unfortunately your device is not fully supported by Nokia PC Suite 0r
Nokia PC Suite Nokia N900 USB device connected in a non-compatible USB mode.

There are other issues as well, but I figure if I start by correcting this one, the rest may follow.

Any insightful suggestions, anyone?

Thanks!

Have you tried with a different USB port? What about a different USB cable?

Have you selected "PC Suite Mode" upon connecting the device? (on the n900 screen you have two modes after you insert the usb cable: Mass storage and PC Suite)

This is just a warning meaning that some features are not available.

Yes, this is a known and solved problem. All you have to do is find that file as downloaded and right-click it and select Properties. Then you will find a category called Compatibility. Pick something like Windows XP Serviice Pack 3 (that's what I picked) and it will work fine.

This should be on a FAQ here somewhere, I would hope.

(I'm assuming you are running Windows 7.)

Perhaps the other comment is correct, too. It was so easily solved I didn't pay much attention.

He's not running Windows 7 apparently.

Oops, right you are, sorry.

i had the same problem, have you restarted your PC? (and the phone maybe too).

I can successfully connect N900 to Nokia PC Suite using Windows XP SP3. I believe I have the latest version, too (I have upgraded fairly recently).

Have you checked you selected "PC Suite mode" on N900 when connecting USB cable? If you hit "Mass storage" you'd get similar message from PC Suite.

PS
Oops... Just noticed someone already asked the question. Can the OP reply?

OK, folks: It is one of these times that I feel really DUMB.
If the phone is switched "on", everything is OK.
If it is not, the error messages in my OP appear.

Thanks, all for your interest in helping a newbie!

What is the software version you're using? (Settings/About)

In versions before the current (2.2009.51-1) the phone didn't "wake up" when USB cable was connected, so couldn't go to PC Suite mode. I am assuming that by "on" you mean "screen on". If your phone is powered off completely, it should be fairly obvious it won't work...

Try updating to the latest software in Application Manager.

PS
I have filed a bug against the latest software as I do not think that plugging in a USB cable with screen off should wake up the phone. It should just start charging, as it was (often, but not always) the case in the previous versions.

I have updated to version 2.2009.51-1.002 after my original post in this thread.
And "on" means (to me) that the unit is powered up.

Thanks, everybody, for this discussion.
It has been very helpful.

I do have another problem: when the phone is "on", and I push the power button, it does not always switch "off".
However, I'll call Nokia tech support, and if they can not resolve this, I'll ask this forum in a new thread.

Thanks again!!
