Hi. I'm David, and I'm happy to help you.
The "Code 45" occurs if the device that was previously connected to the computer is no longer connected.
I don't rule out it being a driver problem. However, this may also be a hardware problem.
Since the device does not have internet access, you will need to download the drivers using a device with internet access, transfer the files to the device without internet access (Using any external storage device), and then install the drivers.
Drivers are developed by the device manufacturer, so download them from the support area of the device manufacturer's website.
If you want, I can search for you and point you to the drivers, but I need some information about your system.
Please share a screenshot of your system information.
- Press "Windows + R", type msinfo32 and press Enter.
Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool. Or take a picture of the screen using a camera or smartphone and share it.
I await your reply. Click on the "Reply" button below my reply.
