Hello to the community.
Following an update, I have a problem with the recognition of devices connected via USB ports.
When the computer is turned on, they are recognized, but if I remove them and plug them back in without restarting the PC, they are no longer recognized. If I restart, they reappear....!!!!
Checking in the Device Manager confirms the problem (exclamation mark). I suspect a driver issue.
The PC is up to date and I have tried uninstalling the device via the Device Manager.
I don't know how to remove the faulty driver to reinstall it.
From reading the forums, I gathered that it might concern "USBSTOR" but I'm not sure.
The problem persists.
Thank you for your help.

    Hello,

    What is the brand and model of the PC..? And the version of Windows..?

    How many devices are connected via USB..?

    -- If you don't have a power block for the USB, it might simply be a lack of electrical power.
    USB ports being limited in current.
