Windows 10 and USB Network Adaptor problem (TomTom & BlackBerry)

Hi all.

I have a problem with two USB devices (BlackBerry Q10 and TomTom GO 5000) which previously worked with Windows 10 but have stopped working.

Both use their own software and drivers and both appear as Network Adaptors in Device Manager when I connect them. Device Manager says that they are working properly.

I didn't connect either device for a while but have needed to connect them recently (to update the TomTom software and to access files from the BlackBerry internal storage). Now, the TomTom locks up when it is connected by USB (and is fine again as soon as the cable is unplugged) and the BlackBerry brings up a message saying that drivers are not installed. Both devices appear in Device Manager when they are connected.

Both devices' apps say that they are trying to find a device when the USB is connected, but never find the devices. As soon as the device is unplugged, the app stops searching and the device disappears from Device Manager.

I've tried this on two PCs, one running Windows 10 Home (1703) and the other running Windows 10 Pro (1607). I know that both devices worked fine in v1511 on both machines.I've tried uninstalling and reinstalling the apps & drivers. I've manually deleted all files relating to the apps and used uninstaller programs to try to remove all files and reg keys. Nothing has worked.

As both devices worked fine in 1511 and appear as Network Adaptors and seem to be responding in similar ways when they are connected / disconnected, I'm wondering if this is a problem related to the way that Windows handles USB network devices. It might possibly affect similar devices in the same way and I'm hoping that someone has found a fix.

Any suggestions?

Many thanks!

Have you uninstalled the TomTom and the Blackberry in device manager and let Windows reinstall?

Thanks for the reply. I have now tried this with the BlackBerry but it just sat in Device Manager as an "Unknown device" and all options to search for a driver failed.

I have had a bit of a breakthrough on the 1703 PC though. I wondered if I needed to enable file sharing on the BlackBerry network specifically. Whilst I didn't find an option for that, I found the option to share the BlackBerry's internet connection with other PCs on the network. As soon as I did that, it all came to life and the two network drives (internal and SD) installed themselves. I then tried to replicate this on the 1607 PC but the BlackBerry isn't showing in the Network Connections screen, so I can't enable that setting on it. I'll try this with the TomTom tomorrow.
