Overview of the Error

If you are not able to connect your device to your PC using a USB to Serial adapter it may be that

  • The USB driver is outdated
  • The USB Driver is missing
  • Or even a corrupted driver

While you can't be so sure what the exact problem is there are solutions you can adopt to fix the issue once and for all. Read on to find quick fixes to resolve the problem.

1# Fix Prolific USB to Serial Driver not Working

Solution: Roll your Prolific USB to Serial Driver back to an older version

Updating your drivers often work wonders for your system because it makes sure that it runs on the latest features that guarantee maximum functionality. Unfortunately updating your drivers can cause this kind of error especially if your latest update does not work too well with your hardware. Once you upgrade your PC to the latest Windows version your Prolific USB to Serial Driver also updates to the latest driver software and if the driver is not compatible with your Hardware issues may arise. To correct the error, you will have to download the driver again by following these steps.

  • Right-click on your PC Start button and open Device Manager
  • Double click LPT and COM ports then locate the Prolific USB to Serial Driver and right-click it so you can select Update Driver
  • For driver software click My computer

Driver
  • Choose an older version from the list then click Next
  • The driver you selected will be installed automatically
  • Once it has been downloaded reconnect the driver to see if it works.

2# Fix Prolific USB to Serial Driver 'Coder 10'

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.

  • 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

You can use Android Debug Bridge (ADB) to connect your Fire tablet to your computer for testing and debugging. You connect your computer to your Fire tablet through a micro-USB cable.

Android Debug Bridge (ADB) is a command-line utility for running and managing Android apps on your device or emulator. For more information and instructions on using ADB, see Android Debug Bridge.

If you're looking for instructions on connecting to a Fire TV instead, see Connect to Fire TV Through ADB.

  • Check for Device Connections Using ADB (Optional)
  • Troubleshooting

Step 1: Enable Developer Options

  1. Go to Settings > Device Options and look for a Developer Options menu. If it's not there, do the following:

    a. Go to Settings > Device Options > About Fire Tablet.b. Tap your Serial Number seven times.c. Return to Device Options. A new menu appears called 'Developer Options.'

  2. Tap Developer options. (2013 models might call this option 'Security.')
  3. Set Developer options and USB debugging to ON.
  • If you have a Kindle Fire 1st Generation, ADB is enabled by default.

Step 2: Install the Kindle Fire Driver (Windows Only)

  1. If you're using Windows, download this Kindle Fire driver: kindle_fire_usb_driver.zip.
  2. After downloading the file, extract the contents into a new folder and double-click the Fire_Devices ABD drivers file.
  3. Proceed through the installation wizard screens to install the driver.

Step 3: Install Android Studio

ADB is available on your computer when you install Android Studio. If you don't already have Android Studio, download and install Android Studio. If you're not using Android Studio, you need to download and install Android SDK platform tools.

Step 4: Connect Your Fire Device to Your Computer with a USB Cable

  1. Using a USB cable, connect your Fire tablet to a USB port on your computer.

    Note that Fire tablets can treat the USB with different transfer options. After connecting the USB cable, swipe down from the top of your tablet to see the USB option used. You might see various notifications, including the USB connection type that was used when you connected the cable. The relevant notification is highlighted in the screenshot below.

    If you don't see 'Connected as Media Device', press Tap for other USB options. Then select Media device (MTP). Later Fire OS versions have a different interface here. If you're using Fire OS 7, select File Transfer.

    Note: If your USB is connected as a Camera (PTP), Android Studio won't recognize the tablet as a device in Android Studio.

    If you don't see the USB connection type in the above notifications, go to Settings > Device Options > Developer Options > USB computer connection. Set this to Media device (MTP). For Fire OS 7, select File Transfer.

  2. When the Allow USB debugging? dialog appears on your tablet, tap OK.

  3. Open Android Studio and look for the device to appear in devices drop-down menu:

    The device's name will use the android.os.Build.MODEL property for the device. KFSUWI refers to Fire HD 10 (2017) tablet. You can see a list of build model names in the Identifying Fire Tablet Devices.

    If you have not selected the 'Allow USB Debugging' dialog on your tablet, the name 'Unknown device' will appear in the devices drop-down menu in Android Studio until you allow debugging.

  4. With the tablet connected, you can now run your app on your tablet by clicking the Run App button in Android Studio.

If you run into issues, see the Troubleshooting section below.

Check for Device Connections Using ADB (Optional)

Instead of looking in the devices menu in Android Studio, you can also use some ADB terminal commands to confirm that your device is connected. ADB is useful for performing many other operations as well, such as entering sandbox mode or installing other assets. Follow these two sections:

If you skip adding ADB to your PATH, you can also Check for Connected Devices If ADB Isn't In Your PATH.

Add ADB to Your PATH

First, add ADB to your PATH so you can more easily run ADB commands. (Your PATH is an environment variable used to specify the location of the program's executable. If you don't add ADB to your PATH, running ADB commands will require you to browse to the <Android SDK>/platform-tools directory to run adb.)

Tip: You can check whether ADB is already added to your PATH by typing adb version from a terminal or command prompt. If you get back version information, then ADB is in your PATH. If the response says adb is an unrecognized command, ADB is not in your PATH.

To add ADB to your PATH on Mac:

  1. Get the path to your Android SDK platform-tools directory:

    1. Open Android Studio and click the SDK Manager button .The location to your Android SDK appears near the top next to Android SDK Location. For example: /Users/<your username>/Library/Android/sdk

      If this is your first time opening Android Studio, there isn't an SDK Manager button. Instead, at the Welcome to Android Studio prompt, click Configure > SDK Manager and provide the location to the Android SDK.

    2. Copy the path to the SDK and paste it somewhere convenient, such as a text editor.
    3. Add /platform-tools to the end of the path you copied in the previous step. ('platform-tools' is the directory containing the ADB executable.)
    4. Copy the full path to your clipboard.

  2. Use the following command to add ADB to your .bash_profile. Replace <your username> with your actual username. Also, make sure the path points to your Android SDK.

    Your .bash_profile file is usually in your user directory, which you can find by typing cd ~ (change to your user directory). Then type ls -a (list all) to show all files, including hidden ones.

    If the file isn't there, simply create one. You can then type open .bash_profile to see the paths listed.

    After you add this PATH to your bash profile, you should see the following in your .bash_profile file:

    (Only instead of johndoe, you will see your own username.)

  3. Fully restart any terminal sessions, and then type adb. If you successfully added ADB to your path, you will see ADB help info rather than 'command not found.'

To add ADB to your PATH on Windows:

  1. Get the path to your Android SDK platform-tools directory:

    1. Open Android Studio and click the SDK Manager button .

      The location to your Android SDK appears near the top next to Android SDK Location. For example: C:Users<your user name>AppDataLocalAndroidSdk

      If this is your first time opening Android Studio, there isn't an SDK Manager button. Instead, at the Welcome to Android Studio prompt, click Configure > SDK Manager and provide the location to the Android SDK.

    2. Copy the path to the SDK and paste it somewhere convenient, such as a text editor.
    3. Add /platform-tools to the end of the path you copied in the previous step. ('platform-tools' is the directory containing the ADB executable.)
    4. Copy the full path to your clipboard.
  2. Click your computer's search button (next to Start) and type view advanced system settings.
  3. Click View advanced system settings.
  4. When the System Settings dialog opens, click the Environment Variables button.
  5. Under System Variables (the lower pane), select Path and click Edit.

  6. Do one of the following:

    • On Windows 7 or 8, move your cursor to the farthest position on the right, type ; and then press Ctrl+V to insert the path to your SDK that you copied earlier. It may look like this: ;C:Users<your user name>AppDataLocalAndroidSdkplatform-tools. Click OK on each of the three open dialog boxes to close them.
    • On Windows 10, click the New button and add this location.
  7. Restart any terminal sessions, and then type adb. If you successfully added ADB to your path, you will see ADB help info rather than 'command not found.'

Check for Connected Devices

  1. Assuming ADB is added to your PATH, run the following commands:

  2. Confirm that the serial number for your Fire tablet appears in the list of devices. For example:

    On your tablet, your device's serial number is located under Settings > Device Options.

Check for Connected Devices If ADB Isn't In Your PATH

If your terminal doesn't recognize adb as a command (that is, you didn't add ADB to your PATH), you might have to run the commands from the SDK directory that contains ADB.

  1. In Android Studio go to Tools > SDK Manager.
  2. In the SDK Manager dialog box, copy the Android SDK Location.

  3. Browse to this location in your terminal or command prompt. For example:

    Mac

    Windows

    Then go into the platform-tools directory:

    The platform-tools directory contains adb.

  4. Now run the ADB commands as follows:

    Mac:

    Windows:

    The response should list your device's serial number. For example:

    If your Fire tablet is still not detected, you may need to reboot your computer or log out and back in for the changes to take effect.

Troubleshooting

Tablet doesn't appear in list of devices in Android Studio

  1. If you don't see your tablet device in the list of devices in Android Studio, click the devices drop-down menu and select Troubleshoot device connections:

  2. Click Rescan devices.

    If rescanning devices doesn't detect your Fire tablet as a device, your micro-USB cable might be bad, you might have the wrong USB connection type (e.g, camera instead of media device), or you might not have enabled USB debugging. You can also try restarting your computer and the tablet.

Uninstall the non-ADB Driver (Windows)

If you previously connected a Fire tablet without first enabling ADB on the Fire tablet, you might need to remove the existing USB device driver and force re-installation of the driver. To remove the non-ADB driver:

  1. Using a micro-USB cable, connect your Fire tablet to a USB port on your computer.
  2. On your computer (Windows 10), click the search button (next to the Start menu) and type Device Manager in the search. Then select it in the results. (Other Windows versions have different options for accessing the Control Panel.)
  3. In the Device Manager window, expand Portable Devices.
  4. Right-click the Fire device and then click Properties.
  5. In the Properties window, on the Driver tab, click Uninstall, and then Confirm.
  6. Unplug your Fire tablet from your computer.

Confirm the Fire Driver Is Installed Correctly
