Issue 1: "Device Descriptor Request Failed" in Device Manager

Cause: Windows 11’s power management polling the RS1081B too aggressively. Fix:

Go to Device Manager > Universal Serial Bus controllers > USB Root Hub (right-click) > Properties > Power Management.
Uncheck “Allow the computer to turn off this device to save power.” Do this for every USB Root Hub.

What rs1081b likely refers to

rs1081b appears to be a hardware/driver identifier (vendor or device model string). It is not a widely recognized, standard Windows device name; it may be:

A chipset, network adapter, or USB device model string from a vendor-supplied driver package.
A truncated or mis-typed device ID (for example, PCI/USB hardware IDs like VEN_xxxx&DEV_xxxx).
A custom or niche peripheral model that requires a vendor driver.

Step 2: Disable Driver Signature Enforcement (Temporarily)

Windows 11 blocks unsigned or outdated drivers. You must boot into “Disable Driver Signature Enforcement” mode. Go to Device Manager > Universal Serial Bus

Open Settings → Update & Security → Recovery.
Under “Advanced startup”, click Restart now.
After reboot, choose Troubleshoot → Advanced options → Startup Settings → Restart.
Press 7 or F7 for “Disable driver signature enforcement”.

Your PC will boot into a special mode allowing legacy drivers.

5. If all else fails

The RS1081B is likely an older or very specific chip. You may need to:

Contact the manufacturer of the device (not the chip)
Replace the device with a Windows 11 compatible model (e.g., any modern CCID-compliant smart card reader)

Can you provide the Hardware ID from Device Manager?
If you share the VID_xxxx&PID_xxxx, I can help you find the exact driver.

Step 4: Verify Installation

Device Manager should show the NIC under Network adapters without a yellow triangle.
Open Control Panel → Network and Sharing Center → Change adapter settings. Your Ethernet adapter should appear.
Plug in a cable — lights should blink (if present on the card/port).
