Hello

Thank you for posting in Q&A forum.

The CT QUALCOMM U drv is likely related to a Qualcomm USB modem or serial device driver. To locate and uninstall this driver, you can follow these steps:

1. Open Device Manager, Look under Network adapters or Modems for any Qualcomm-related entries.

In Device Manager, click on View and select Show hidden devices. This might reveal the Qualcomm driver if it’s not immediately

2. Use Command Prompt to Uninstall

Run the following command to list all installed drivers:

pnputil /enum-drivers

Look for entries related to Qualcomm. They might be listed as oemXX.inf where XX is a number.

Uninstall the Driver:

pnputil /delete-driver oemXX.inf /uninstall

Replace oemXX.inf with the actual name of the Qualcomm driver you found.

3. Check for Remaining Files

Negative to C:\Windows\System32\drivers.Look for any files related to Qualcomm (e.g., ct_qualcomm_u_drv.sys) and delete them if found.

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and look for any entries related to Qualcomm. Delete them if found.

4. Restart Your PC.

I hope the information above is helpful.
