Windows cannot start this hardware device... (Code 19)
So I get the error "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)" in device manager for all portable devices even though I'm sat here with an external HDD copying data just fine.
This seems to affect all external USB drives I plug in plus my multi-card reader. The issue seems to have cropped up after I changed the drive letters of my card reader via disk management and I don't know if or how to reset them to default drive letters if that is even a thing.
The weird thing is as I say that when I plug in an SD card or USB external they all work fine but device manager says they are all error code 19.
Updating drivers doesn't do anything as Windows reports drivers already up to date. Uninstalling these devices and restarting PC doesn't work either.
The only other thing I've found out about this type of issue is that deleting upper and lower filters in the registry may help... but... I don't know which upper and lower filters to delete as most troubleshooting refers to CD-ROM errors. I have no CD-ROM error, and I don't know if deleting the entries for disk drives will do anything other than break something else. There seem to be no entries related to portable devices specifically.
