Answer 1

The message indicates a standard Device Manager error Code 43 plus a failure in the USB Type‑C UCSI stack.

1. Meaning of Code 43

• "Windows has stopped this device because it has reported problems. (Code 43)" means a driver controlling the device has told Windows that the device failed.
• Recommended generic resolution is to uninstall and reinstall the device in Device Manager.

Steps:

1. Open Device Manager (right‑click Start > Device Manager).
2. Find the device with the warning icon that shows Code 43 in its properties.
3. Right‑click it > Uninstall device.
4. In Device Manager menu, select Action > Scan for hardware changes to reinstall the driver.
5. If prompted for a driver and it is not available locally, download the latest driver from the device or PC manufacturer and install it, then reboot.
6. UCSI PPM / USB‑C specific part

• The message "UCSI PPM failed UCSI command" relates to the USB Type‑C connector system software interface (UCSI) driver and its Platform Policy Manager (PPM).
• The error text explicitly says to contact the UCSI device or system manufacturer. This is because the failure is in the platform’s USB‑C/UCSI implementation, not something that can be fixed only from Windows settings.

Practical actions:

1. Update or reinstall chipset/USB‑C/UCSI drivers from the PC or motherboard manufacturer support site (often bundled in chipset or “USB‑C”/“Thunderbolt” packages).
2. After installing updated drivers, restart the PC and check Device Manager again for Code 43.
3. If the error persists with the latest vendor drivers, contact the system manufacturer’s support and provide the exact UCSI error text, as recommended by the message.
4. If Code 43 persists on a graphics or other device

• For graphics devices with Code 43, update the driver via Device Manager (Properties > Driver > Update Driver > Search automatically) or from the GPU vendor’s site.
• If the problem started after a recent driver update, use Device Manager > Properties > Driver > Roll Back Driver to return to the previous version.

If, after driver reinstall/update and a full restart, the device still shows Code 43, this usually indicates a deeper driver or hardware fault and needs vendor investigation.

I HAVE FOUND A BETTER ANSWER.

THERE IS AN OPTION ON DELL WHIHCH DISABLES THE RIGHT SIDE USB CONNECTER ON MY LAPTOP WHICH IS DELL INSPIRON 5410 WHICH IS THE ACTUAL ERROR OF CODE43.

PLEASE TRY IT OUT AND SEE, YOU WILL FIND IT OUT AND 11TH,12TH GENERATION PROCESSORS HAVE NO SUPPORT FROM DELL FOR DELL SUPPORT ASSIST.

I HAVE NOT SHOUTED AT YOU BY WRITING CAPITAL LETTERS BUT THIS IS HOW THEY ARE CHEATING EVERY INDIVIDUAL.

THANK YOU FOR THE ANSWER IT HAS SOLVED MY PROBLEM.
