To test this, I went to disable Selective Suspend in the advanced power profile settings but found the USB Settings option missing.
Windows 10 kept trying to enable Selective Suspend on the port and that caused the connection to drop because the TomTom driver wasn’t updated to let Windows 10 know it could not enabled suspend on the port while the GPS was connected and trying to update a 6gb map.
After about an hour of reading it appeared based on some user forums that Selective Suspend was to blame because the TomTom MyDrive software and GPS driver were not configured to support Selective Suspend in Windows 10. This time I started researching USB connection issues with my GPS and Windows 10. I did a few other things, took a shower, and then came back to start again. Sometimes when troubleshooting an issue, you can lose the forest for the tress so I decided it best to take a break. After another hour of testing and messing with it I still had no luck and by this point my GPS map was totally hosed because of the constant connecting and reconnecting. Was the micro USB port on my GPS bad? Seemed unlikely but I checked it out. Must be a cable problem, right? I tried 3 different cables and they all had the same issue. So I unplugged the Surface Dock completely and still the GPS would connect and then drop its connection. I then plugged the GPS USB cable and plugged it directly into the Surface. It would update for a few seconds and then say it wasn’t connected. I plugged the GPS into one my Surface Dock USB ports and told it to update but it kept dropping its connection. The convenience of the new Surface Dock with its single connection into the Surface that provides communications and power was totally lost.Ī few days before Christmas I decided to update my TomTom GPS with the latest map before we did some traveling for the holiday. Without any solution I continued to unplug my new Surface Dock from my Surface multiple times every day to wake up my monitors. I had a hunch all along it was either a firmware issue with the Surface Dock or it was a driver issue on the Surface itself. I hooked the new one up and the same problem. They told me it was probably a hardware issue with the Surface Dock so they sent me another one. Randomly they would come back on but most of the time in order to use my monitors connected to the Surface Dock I’d have to unplug the Surface Dock Connector from my Surface and then plug it in again.Īfter spending weeks trying to figure out why the monitors wouldn’t wake up I finally broke down and called Microsoft support. The biggest issue I faced was that my display port monitors would go to sleep and rarely wake up when connected to the dock.
Then I got my Surface Pro 4 and the new Surface Dock and things started to go south in a hurry. I started using Windows 10 on a Surface Pro 2 using a Toshiba USB 3.0 dock to connect to my keyboard, mouse, and dual monitors. This has been around since Windows XP and USB 2.0 so you’d think that it is widely supported. One more gotcha here, the driver for the USB device must support Selective Suspend in order for it to work properly. Windows 10 hides that setting unless you modify the registry. That’s why Windows allows you to enable or disable USB Selective Suspend based on the computer being plugged in or on battery power.Īnother interesting fact here is that previous versions of Windows allows you access to the USB Selective Suspend setting easily in the advanced power profile settings. Now on a laptop or tablet on battery power it’s a different story. Powering down USB ports won’t save the grid that much power on a desktop. What’s bad about it is that it really isn’t necessary on a desktop machine that is plugged into power. What’s cool about it is that it can do USB ports individually without powering down all the USB ports or the entire USB bus. Selective Suspend allows the operating system to save power by placing specific USB ports into a suspended mode to save power, similar to how a laptop or tablet can be placed into sleep mode.
It has been around since USB 2.0 in Windows XP. If you are experiencing or have experienced issues with USB devices and Windows 10 then hopefully you can keep reading and save yourself the hours of frustration and rage inducing failures that I’ve been dealing with since first starting to use Windows 10.įirst a bit of background, USB Selective Suspend is not new. Recently I lost hours of my life due to an odd USB setting in Windows 10.
