USB3.0 ports (Windows 10) won't recognise USB2.0 external drive (DVD/CD ROM)

HP Recommended
HP Envy x-360
Microsoft Windows 10 (64-bit)



I have a cheap, brandless USB 2.0 external DVD/CD ROM drive that claims to be 'plug and play'.  I have two laptops, a HP Envy notebook and a Dell Latitude e490, both new (late 2019) machines, both running off Windows 10 and both with 2 x USB 3.0 ports. The external drive powers up when I plug it into the ports (the disk spins and the lights flash green), but the laptops won't recognise it as a device on device manager or My Computer and therefore it just goes back to sleep.


If I go into device manager, the two laptops both have 1 or more USB Root Hub (USB3.0), USB Composite device, and either the AMD USB 3.1 eXtensible Host controller - 1.0 (Microsoft) (the HP) or the Intel(R) USB 3.0 eXtensible host controller - 1.0 (Microsoft) (the Dell).

- I've tried uninstalling all these drivers and restarting for windows to reinstall, including the UCM-UCSI ACPI Device(s)

- I've tried checking for updates by checking each driver individually and through the HP assistant

- I've checked for BIOS updates

- I've experimented with the boot order in the BIOS (putting the 'USB CD/DVD Rom drive' and the 'USB diskette on key/USB Hard disk' above 'OS'. Those are the only three things on the list)

- I don't seem to have anything called 'chipset' to check for updates - that was something else that's been suggested for similar issues on forums


As you might have guessed, none of the above made any difference!


Please does anyone have any ideas of what I need to do to make the external drive work?
