[SOLVED] Error Code 38 for USB Devices

[raya2]

In the last 10 days I encountered with a problem for some of the USB devices that can not be recognized by Windows, after unplugging them from PC. (I always use safe to remove function)

- It happens to USB HDDs, USB flash drives & USB modems. (& doesn't happen for non-data-based USB devices like mouse & keyboard &...)

- The USB device shows a yellow triangle in the device manager with this error inside:

"Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)"

- Disabling or uninstalling the device driver won't work.

- The only thing that works is to restarting the PC, that it's not a good solution, when I don't want to restart my PC every few hours!

- I tried booting my PC in safe mode & cleaned the registry there, but it doesn't helped.

- Using hardware troubleshooting for problematic USB drives, doesn't helped too.

- I even used an app named "USB Oblivion" for cleaning the previous instances of USB device drivers, but it doesn't helped too.

- The BIOS of mobo is the last one.

- I have an up-to-date version of Windows 10 Pro. (19043.1503)

Please gives me solutions, so I can fix this problem.

You have an update pending for your OS.

We're going to need a little more information. Please list the specs to your build like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:

Include the age of the PSU, apart from it's make and model. Then use CPU-Z to see what your motherboard's BIOS version is. As for your OS, might it be possible to state where you sourced the installer from?

OK, I found the problem & fixed it.

The problem is related to a bug in the free edition of Bitdefender antivirus.

Uninstalling the Bitdefender, solved the problem.

Thanks to anybody helped me here.
