📎 AI Summary:
The thread discusses a Windows 10 user whose SD card reader is not functioning on their HP Pavilion desktop, despite working on their laptop. The device appears as an 'unknown device' with a driver installation error related to the USB controller, and they're seeking advice on whether this indicates a hardware failure. The first suggestion recommends downloading the appropriate driver directly from the laptop manufacturer’s website.

My SD card is not detected - no sound on insertion into the integrated card reader, invisible in File Explorer, Device Manager and Disk Management on my desktop (HP Pavilion 500, Windows 10 Home, all updates) . It works fine on my laptop however. I see 'unknown device' under 'Other devices' in Device Manager, with a yellow triangle against it. When I try to update the driver for this 'unknown device' I get the message:

"Windows found drivers for your device, but encountered a problem while attempting to install them

Intel (R) 6 series/c200 series Chipset family USB enhanced Host controller 1C26

The driver file for this device is missing a necessary entry. Contact your hardware vendor."

Grateful if anyone can suggest whether the above points to a hardware failure of the card reader? I've run update checks on the Intel site, but no issues were flagged.

Thanks.
