Android phone doesn't pops up with "USB connected" message We have a Samsung GT i5800 with Android 2.1update1.

When I put a memory card in it, it recognizes it, great!

But: When I want to connect the phone via USB to my PC: this picture DOESN'T comes up: 




And I can't see my memory card through my phone from my PC!

On other phones, the memory card is OK. (tried another android phone).

The USB cable is good, tried it with another phone.

What could be the problem? Are there any settings that I missed?
Check Settings -&gt; Applications -&gt; USB Settings or Settings -&gt; About Phone -&gt; USB Settings, rather than the network settings.

I would also try a different USB cable, just to make sure, as well as a different USB port and a different computer if you can.  You can try wiggling the connector in the device as well and see if it makes proper contact intermittently.

As Al notes here this sort of problem seems to come up pretty often with Sasmsung phones, so you might just be out of luck.  If all else fails, though, I would try a factory reset.
