"Internal module error" PROBLEM SOLVED ! ! !

Question

At least in my case.
I tried to update my phone (Nokia E50, prod. code: 0536382) with NSU, but I always got the frustrating "Internal module error" message. I spent a whole afternoon trying. After several attempts without any success I accidentally discovered the solution. When the error message appeared again, I noticed, that the small USB icon right below the battery level indicator is gone - so is the connection. How to restore the connection? The NSU says, you should not disconnect the phone, so why the connection interrupts during the update? (I suppose that NSU does the download first and in the meantime nothing happens to your phone. During the download your PC may shut down the USB port to save power. When the download from the internet is done, NSU tries to upload the software to the phone, but there is no connection anymore.) After digging deeply through the Device Manager of my PC, I found an option that turns the USB port off after a while, to save power. That is where the connection goes away.
So, do the following:
1. Go to Device Manager;
2. Under Universal Serial Bus controllers find the USB Root Hub your phone is connected to (assuming you use a USB cable to connect);
3. Double click it and then go to the Power Management tab;
4. Uncheck the option "Allow the computer to turn off this device to save power."
5. Disconnect the phone, reconnect and proceed with NSU.
You should be able to update the phone successfully.
Good luck!

So far the "Internal module error" problem seems to be connection related.
Make sure, you have the Nokia Cable Connectivity Cable driver installed (the later the version the better), if you are using a cable. You may check it out in the Control Panel->Add or Remove Programs.
You also make sure you enter the right Product Code when asked. The following link may help you clarify the fog around the firmware version number:

It seems there are several versions. Check out the differences and upgrade only if you need it.
As for the USB, in Device Manager got to Universal Serial Bus controllers, and double click every USB Root Hub. On the Power tab you may see the all the devices connected to the specific USB port. Let me know, if you find something out. Cheers.
