When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Common USB Device errors are ‘usb port not working‘, ‘device descriptor request failed error’ or ‘bugcodeusbdriver. If you have to manually install a driver for the device — perhaps the driver is already installed on your system — you can use the Update Driver button in the device’s Properties window. If the device driver is already installed on your system, click the “Browse my computer for driver software” link and choose an installed driver. The offending xHCI device was gone. I then proceeded with a cycle of restarting and re-enabling them one by one (with restarts and logins into Windows each time to check Device Manager). Once they were all re-enabled, the problem was gone from Device Manager and the touch screen worked again. Thanks a bunch for the fix.

2# Fix Prolific USB to Serial Driver 'Coder 10'
Hidalgo Port Devices Drivers
Driver issues reveal themselves in so many ways or through messages such as
- This device will not start (Code 10)
- There is no driver installed in this device
- The driver was not successfully installed
A code 10 error may arise because the chip you are using is not an original one. If you are using a fake, the manufacturer has a way of disabling it due to copy write infringement and the copy write takes effect once you download a recent update. To protect your PC from getting this code, you will have to make sure that your Windows 10 never updates a driver without approval. Updates come in the form of 64 bit and 32-bit drivers. Below we will show you how to work your way around the problem.
Window 64 bit Fix
To fix Windows 64 bit OS including Prolific USB to Serial Adapter, follow through these steps.

- Download 'PL2303_64bit_Installer.exe and Save
- Remove every USB to Serial adapter from your PC and double click the 'PL2303_64bit_installer.exe
- Follow the prompt by plugging in one USB to Serial adapter the click on Continue
- Reboot your PC to get Windows up and running
If you have followed these process through and you still see the same error go to your device manager
- Open the control panel and navigate to Device Manager
- From your control panel navigate to the System category and click the Hardware tab
- Scroll to the LPT/COM port and double click Prolific USB to Serial Comm Port
- Click Drivers in the Properties section
- The Driver you choose should read '3.3.2.102 with an appropriate date attached
- If the date is wrong then it means the wrong driver was installed
- Unplug the Serial adapter and run the steps again to install the correct driver
Window 32-bit
For Windows 32-bit OS systems follow these steps
- You will have to download the 'PL-2303_Driver_Installer.exe and save from Microsoft download link
- Run the program and eradicate the driver if you can
- Run the installer once more to install a correct driver
To Troubleshoot for error if your device still does not work
- Go to Control panel, enter System to access your Device Manager
- Scroll down to the LPT/ COM port then double click Prolific USB to Serial Comm Port
- Click Driver in the Windows Properties section
- The driver must be numbered as '2.0.2.8' and dates accordingly
If the driver was not installed, remove the Serial adapter then run 'PL2303_Driver_Installer.exe' again. Follow directions in Device Manager to download the correct driver
The three solutions listed in this article have proven to be quite helpful in fixing a Prolific USB to Serial driver not working on Windows 10. They may appear confusing at first but if you follow each step in detail you can resolve the issue.

I recently bought a development board Arduino NANO, wanted to use for a project that needed a small size and Arduino NANO was the perfect candidate for the Arduino project.
By taking the card and connect it to my computer, I thought it would recognize immediately as another card Arduino, but I got the surprise that the device does not recognize by my computer, so I gave myself the task of updating the port USBdriver, look everywhere, download countless programs and USB driver, but to no avail. Finally after almost four hours of failed attempts, check the integrated circuit that controls communication betwen PC and Arduino NANO.
What differences I found on the Arduino Nano and USB port?
The Arduino NANO like other Arduino cards, have a chip which enables the USB connection, and if this is original, brings the reference FT232RL, but in some cases is a Chinese clone and if so, bring a chip whose reference is CH340G . By bringing a different chip, our Arduino software does not have the driver for that integrated circuit, which prevents be recognized and therefore it requires updating, browsing I found a Russian page where is the USB driver for this chip, so I leave the following LINK where you can download the USB driver for Windows. If your antivirus has this file as suspicious, do not worry it does not contain virus, install it without any problem, without virus and it has worked very well, I solved the problem immediately, it is an executable file.
This file has work me well, but I clarify that I am not the author of it and therefore the download and installation runs under your responsibility.
When you download the file comes in a compressed file, so you have to unzip and install it, once you’ve installed, I recommend that you restart your PC and if everything was left properly installed, connect your device Arduino NANO and will be recognized immediately.
Soon I’ll be doing some projects with the Arduino NANO they can surely interest to you, so I invite you to continue visiting my page and subscribe to my youtube channel where I am uploading video continuously from different arduino projects.
Until next.
