Connection problems with Microsoft Surface Pro 3 & 4
This is the solution, with all credits to Techguy378.
The reason why I repost this is because something changed on this website and this post could not be found anymore. For me it was the perfect solution:
Sure. At the Windows desktop right click on the start button and click Run.
- Type "regedit" and hit enter.
- When the registry editor opens up go to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Power.
- On the right pane double click on CsEnabled and change the value from 1 to 0 and click OK.
- Then reboot your computer.
This should solve your problem. This is what Techguy378 wrote more. For my problem it was not applicable.
After it reboots then from the desktop right click on the start menu and click on Power Options. Click on Change Plan Settings next to Balanced (or whatever profile you're using). Click on Change advanced power settings. Go to USB settings > USB selective suspend setting. Change this to Disabled and click OK. You should now be good to go. The USB selective suspend setting appears to be the number one cause of random disconnects on any and all TomTom devices, even older ones that use TomTom Home software. I should note that for Surface 3 Pro users at least you will have to give up Connected Standby if you want to use a TomTom GPS unit with this computer. If you reenable Connected Standby then the USB selective suspend feature will be turned back on. This means you sacrifice things like the alarm clock feature in Windows 8.1. I'm not sure if this affects other Windows laptops with Connected Standby support.
