This was a major problem if you are using internet through a USB device. Suppose of a big download/upload breaks for this reason, especially from rapidshare like sites, where Download resume is not supported.
There are two reasons for this. The power scheme of the computer stops USB device after a specific time interval. Or it may occur due to defective drivers. Here is the solution that worked for me.
Disconnect the device and go to device manager. (Right click on “My Computer” and click Manage. From the left panel of management console, choose device manager.)
Expand USB controller (generally at bottom) and change power scheme of each ports. To do it, double click on each port, go to power management tab and uncheck the box
“Allow windows to turn off the device to save power.”
After this, connect your device again and test if it is disconnecting or not. If it is still disconnecting then follow the next step.
Go to the device manager again without disconnecting the device. The device should be listed under USB. Right click on the device and choose Uninstall.
After uninstall completes, disconnect the device, reboot computer and reconnect it again. The computer will load the drivers automatically.
My USB connection with mobile phone was disconnecting automatically. I solved the problem this way.
