This article helps to fix an issue in which Windows 10 doesn't install specific drivers for USB audio devices on the first connection.

Connect your micro:bit to your computer with a USB cable. Click Download to download the.hex file. Move the.hex file from your computer onto the MICROBIT drive. The next section has instructions for the browser that you’re using. STEP 8: Now Connect the Usbasp programmer to the system and it will be listed under other devices in device manager. STEP 9: Right Click and choose Update Driver Software. STEP 10:Now browse and select the folder where the drivers are stored. STEP 11: After selecting the driver folder, click on Next to install the drivers.

• Writing Linux USB device drivers is not a difficult task as the usb-skeleton driver shows. This driver, combined with the other current USB drivers, should provide enough examples to help a beginning author create a working driver in a minimal amount of time. The linux-usb-devel mailing list archives also contain a lot of helpful information.
• To confirm that this is due to a driver verification mismatch, open the Windows Device Manager and navigate to Universal Serial Bus controllers. A yellow exclamation triangle next to the HEX Code USB or Bluetooth interface should be visible.
• The HEX-NET enumerates as an HID device and does not require a special driver. However, there are some HID power management quirks in 8.1 and newer fixed by installing a device-specific 'driver' (actually just an INF file) supplied with the VCDS installer.

Symptom

When you connect a USB audio device to a Windows 10 Version 1703-based computer the first time, the operating system detects the device but loads the standard USB audio 2.0 driver (usbaudio2.sys) instead of the specific device driver.

Cause

This issue occurs because the USB audio 2.0 driver (usbaudio2.sys) isn't classified as a generic driver in Windows 10 Version 1703. Therefore, the system assumes that a compatible, nongeneric driver is installed for the device even though the driver is generic.

This issue also causes Windows 10 Version 1703 to postpone the search for other compatible drivers through Windows Update that typically occurs immediately after you install a new device.

Resolution

To fix this issue, use one of the following methods.

Method 1

To resolve this issue, install update 4022716.

Method 2

If the device-specific driver is distributed through Windows Update, you can manually update the driver by using Device Manager. For more information about how to do this, see update drivers in Windows 10.

Method 3

If the device is not yet connected, first install the device-specific driver, such as by using the appropriate installer. After the device-specific driver is installed, Windows 10 will select that driver instead of the standard USB audio 2.0 driver when you first connect the device.

Note

See the device manufacturer's user guide for specific instructions about how to install the driver.

Method 4

If the driver isn't distributed through Windows Update, you can manually reinstall the driver. To do this, follow these steps:

1. Install the device-specific driver (see Method 2).
2. Open Device Manager.
3. Right-click (or tap and hold) the name of the device, and then select Uninstall.
4. Restart the computer.

When it restarts, Windows will try to reinstall the device by using the device-specific driver.

Some tools require you to enable Diag connection mode in order to fix null / invalid IMEI or flash QCN / EFS. This guide will explain how to enable Diagnostic Mode (Diag Mode) on an Android phone.

Requirements

• Enable USB Debugging on the phone
  
• Setup ADB on the PC
  
• Root the phone (you could use Magisk )
  
• Install Qualcomm USB drivers
  
• Install Qualcomm Diag QD Loader driver @ [ Login / Register to download free]

Steps to enable Diag Mode

Follow the steps below to enable Diagnostic mode (Diag) on an android device

See the video below or @ https://youtu.be/_bEWuzfO2Aw

Connect the phone to the PC (via a USB cable) while powered on. Launch and run the following commands in adb:

Steps to disable Diag Mode

Follow the steps below to disable Diagnostic (diag) mode on an android device

Launch and run the following commands in adb:

Important Notice

• Enabling Diag mode means you might be looking to make a modification to your device. Its recommended you backup your firmware before making any modification in case it gets bricked
  
• Upon your first attempt at gaining root shell access, your phone might prompt you whether or not to grant ADB root access so ensure to keep an eye on your phone (remove lock screen)
  
• Some phone might use USSD code to enable Diag mode without root access. e.g Infinix X623 uses ####8789# . You can search online for any such USSD code for your device model
  
• Some boxes / dongles have the boot into Diag Mode feature

Quote:In this video tutorial, I'll be explaining how to enable and disable Diag mode or diagnostic mode on a Qualcomm Android device using ADB. Diag mode enables you perform advanced functions like writing or restoring qcn, it can also allow you to backup qcn. Writing IMEI etc. For you to enable diag mode, your phone needs to be rooted. We have a guide on how to root using magisk. You also need to have installed your Qualcomm USB drivers. We have a guide on how to do that also. You need to have setup ADB on the PC, we have a guide for that. You need to have the Qualcomm Android device and USB cord.
Now, once you have these in place, you launch device manager and then you leave the phone powered on once in device manager you connect the phone to the PC don't forget the phone should be powered on and take note of what it gets detected as. I have a detection under Portable Devices (Pi Pro). Now, to enable diag mode, you launch command prompt. This is how I'm going to launch command prompt and then you jump to the adb directory although for some devices / laptops you just hold down shift and then right-click and then select open command prompt but I have power shell here so I'm not going to go through that approach. I don't have command prompt here so I'm going to go through this method.
Now, I'm going to copy my adb address folder by right-clicking, selecting copy address then come here (to type) cd *space* right-click to paste the address I'm going to run that again... and then I press ENTER so now I'm in ADB directory so I'm going to run this command adb devices to be sure I have a connection so I've list of device detected. Now I run adb shell and then su . Now at this point, if you are doing it for the first time, you might get a prompt on your device to either allow ADB or to allow shell root access. Either ways, you grant okay. Now, you're going to run this command to boot into diag mode. I'll just copy it here; setprop sys.usb.config diag,adb alright then you tap enter so that is going to enable diag mode.
To confirm, you go back to device manager. Its going to refresh and then you should have an entry like this Qualcomm HS USB Android DIAG 901D so this is your device in diagnostic mode. Now to revert, that is to take the device out of diagnostic mode, you run the same commands if you're starting afresh but if you are where I am currently, you just paste the same command but instead of diag, you change to mtp. it's the same command / procedure. The only difference is mtp or diag. Since I'm in diag mode, I want to revert back to the previous setting which was mtp (just change diag to mtp) and tap Enter oh sorry, I have to run the commands afresh so adb devices adb shell su and then I paste the command but change to mtp and then enter so I check device manager again.
I'm good, I have my device detected under portable devices once again so that's how to enable or disable diag mode or diagnostic mode on a Qualcomm Android device using adb
