Windows 10: All USB devices hidden

None of my USB devices are showing up in File Explorer and they are hidden inDevice Manager. If I plug them in one at a time they were on a powered USB multiplier the only one that shows up is a USB drive the others are a drawing pad, a foot pedal, a portable hard drive, and a CD/DVD device.I would do a System

Device Manager Un-Hiding Hidden Devices

When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

Device can be disconnected when

• Device unplugged (e.g. removing a USB device)
• Turning a device OFF
• Disabling the device in BIOS (then windows won't detect it) or
• Device failure

So

• Check BIOS as suggested
• Check board connections
• Can b/t be turned off by a switch? or keyboard combination?

Also possible the b/t h/w failed

 

When starting computer Renesas USB 3.0 eXtensible Host Controller - 0.96 (Microsoft) and USB 3.0 root hub missing from device manager

Hi,

Since you've mentioned that the USB 3.0 doesn't appear in the Device Manager window. We recommend that you check the BIOS settings your device if the USB 3.0 is enabled. If you've already checked the BIOS settings and found out that it is enabled, we suggest
that you follow these steps:

• Open Device Manager.
• Under the View tab, click Show hidden devices.
• Check Universal Serial Bus controllers if it will show the missing items.

This will show all the hidden devices under Device Manager.

We'll be waiting for your response.

 

USB Webcam showing as Hidden in Device Manager

Hi,

Firstly apologies for not getting back sooner but I've been on holiday for a couple of weeks and didn't have access to my PC.

I'm trying to check whether the webcam is blocked or not by following your instructions. I've followed Step 1 and 2 OK as requested. Your step 3 implies to me that I should now see a list of blocked apps in a box. However when I click on
Allow an app through Windows Firewall what I get is a list of the allowed Apps and Features rather than a list of Blocked Apps. I cannot see webcam or anything similar in the list of allowed apps.

Did I follow your steps correctly. Am I missing something here?

Webcam is still classed as hidden in Device manage and the Camera App still cannot see it.

Regards
