I have an elderly laptop running Windows 10 with regular updates. About a month ago, several plug and play devices suddenly stopped working. Examples of the affected devices are a Huawei Y330-U01 Android phone (about 7 years old), and a camera that is about five years old.
My USB memory sticks still work, as does my Samsung printer (about five years old). An elderly USB keyboard shows up in Device Manager as a USB composite device, and is correctly converted.
The non-working devices don't show up at all in Windows Device Manager. Device Manager doesn't register that anything was plugged into the computer. The phone charges via USB when connected to the computer, that's all.
I wondered if it was the problem described here, but the solution suggested by Microsoft doesn't seem to apply to me. They suggest that you can enable legacy devices manually via Device Manager, but when I follow the instructions, there is simply no option to enable legacy devices on the Port Settings of any COM port. I also can't see LPT1 in Device Manager.
I tried Device Manager | Action |Add Legacy Hardware, but it didn't seem to help either. I installed some drivers, but my devices are still not recognised.
I was on Windows v2004 with full updates until today, when I installed 20H2 (19042.685). There is no change. I had a look for drivers for the phone online, but don't want to download from unknown sites. There are no software downloads available on the Huawei website for this phone. Can anyone suggest how to get these devices working again?
EDIT: I have now solved issues with two devices by downloading software from the manufacturers' website. It was not labelled driver downloads - in both cases, I installed a fancy app with functionality that I don't need. Tested that my devices were recognised, then uninstalled the fancy apps. The drivers remained.
