HMC-KB-US USB-C 5Gbps KEYBOARD (US) 9en1 hub

A): The necessary drivers are already included in all operating systems and install completely automatically, and no additional drivers are needed.

B): Plug the USB hub into another USB port (on the back of the computer where the USB ports are integrated directly into the motherboard). It should re-detect the USB hub and reinstall the drivers. Alternatively, try replacing the USB cable. The obsolete driver of the USB controller could also cause problems. Manufacturers of USB 3.0 chipsets often issue new versions of drivers to improve compatibility with different devices. If the problem with the USB bub persists, plug it into the USB port of another computer to verify its functionality.

A): Drivers are included with operating systems and are installed completely automatically. The card reader is detected as a standard storage device, such as a USB flash disk, no other drivers are available.

B): No other drivers need to be installed and are not even available. If you continue to have problems with your reader, check out more tips that can help you troubleshoot problems.

A): If the card reader is not displayed in "Device Manager," there may be a USB port (or a 20-pin USB 3.0 connector on the PC motherboard in the case of an internal reader) malfunction.

B): Try plugging the reader into another USB port (or another 20-pin USB 3.0 connector on the PC motherboard, if available, in the case of an internal reader). The card reader should be detected and the drivers loaded automatically. If this does not solve the problem, try checking the USB controller status in "Device Manager" in the "USB Drivers" section. If the problem persists, plug the card reader into the USB port of another computer to verify its functionality.

A): If this happens, it means that the operating system failed to get the necessary information to install the drivers.

B): The cause may be a defective USB cable or damaged device. Another option is to remove the record of the connected USB device using "USBDeview". After connecting the reader, the drivers should be reloaded. If the problem is caused by a driver error, the problem should be eliminated. If the problem persists, plug the card reader into the USB port of another computer to verify its functionality.

A): If this happens, it means that the Windows operating system did not assign a drive letter to the new storage device.

B): If the drive letter is not assigned, open "Disk Management", right-click on the desired drive and manually assign the drive letter. Another option is that the correct formatting of the memory card is not performed. Format the card in "Disk Management" or in the device on which you are using the card (for example, the camera).

A): In the vast majority of cases, the USB hub can handle connection of one 2.5" external box. If more external boxes are connected, a higher current is needed that ordinary USB cannot deliver.

B): In this case, an auxiliary power supply is required. Use a USB hub with auxiliary power supply.

A): You can use a passive USB cable to connect a USB hub to your computer. However, with longer cables the USB hub may not work reliably.

B): In this case, we recommend using an active extension USB repeater cable, such as AXAGON ADR-205 or ADR-210.

A): The sound interference is probably caused by the wireless mouse transmitter.

B): We recommend placing the mouse transmitter as far away from the sound card as possible (preferably on the opposite side of the computer – connect the transmitter to a USB port on the front panel of the PC and the sound card to a USB port on the back panel – use a USB extension cable if necessary). In the case of a laptop, place one device on each side.

A): You probably have allowed to listen to the microphone in Microphone Properties.

B): To disable this feature, follow these steps: Start -> Control Panels -> Hardware and Sound -> Sound -> Recording -> Microphone (USB Sound Device) -> Properties -> Listen -> Listen to this device - uncheck this box and confirm with "Apply".

A): Yes, it is possible to play two different tracks simultaneously on one computer.

B): This is primarily a software matter, requiring a player that supports redirecting sound to a different audio output than the one set as the “default” in the operating system. Such functionality is supported, for example, by VLC media player.

You need to set the function of the headphone buttons to track skipping/playback control. 

A) Example setting for Xiaomi phones (HyperOS overlay): 

1st option:

In the notification bar, when headphones are connected, Audio playback via USB > click > Change headphone buttons to Playback control.

2nd option:

Settings > Sounds & Vibration > Sound effects > Change headphone buttons to Playback control.

B) Example setting for Xiaomi phones (MIUI overlay): Settings > Sounds & Vibration > Headphones > Change headphone buttons to Playback – back/next.

The keyboard is set to Apple mode. Switch it using Fn+S (mode for Windows and Android).

 

The keyboard is set to Windows mode. Switch it with Fn+A (Apple mode).

A): If the network card is not displayed in "Device Manager", a USB port (or a PCIe slot in the event of an internal network card) may be malfunctioning.

B): Try plugging the network card into another USB port (or another PCIe slot on the PC motherboard in the event of an internal network card, or temporarily disconnect all other PCIe cards). The network card should be detected and you should be prompted to install the drivers. If the problem persists, plug the network card into the USB port (PCIe slot) of another computer to verify its functionality.

A): If this happens, it means that the operating system failed to get the necessary information to install the drivers.

B): The cause may be a defective USB extension cable or damaged device. If the problem persists, plug the network card into the PCIe slot of another computer to verify its functionality.

A): If this happens, it means that the operating system failed to get the necessary information to install the drivers.

B): The cause may be a defective USB extension cable or damaged device. If the problem persists, plug the network card into the USB port of another computer to verify its functionality.

A): Before connecting the USB network card to an Android device (tablet), you first need to verify with the device manufacturer whether the device supports the Ethernet network feature and also whether the USB network card drivers are included in your specific ANDROID ROM installation.

B): Use a USB connector with OTG support to connect the USB network card to your tablet. If the device (tablet) is equipped with a Mini USB or Micro USB connector, use an OTG reduction or cable to connect it.

A): By initializing the disk, you can set the mode in which the hard disk will work

B): You can use the partition with the master boot record (MBR) or the GUID partition table (GPT). For disk up to 2TB, use the MBR option, we recommend selecting GPT on a larger disk than 2TB. Subsequently, the initialized disk should be formatted.

B): You can use the partition with the master boot record (MBR) or the GUID partition table (GPT). For disk up to 2TB, use the MBR option, we recommend selecting GPT on a larger disk than 2TB. Subsequently, the initialized disk should be formatted.

A): If this happens, it means that the Windows operating system did not assign a drive letter to the new storage device.

B): If the drive letter is not assigned, open "Disk Management", right-click on the desired drive and manually assign the drive letter. If the drive letter can not be assigned to the disk, it is possible that the disk is formatted as "dynamic". If you want to keep disk data, connect it to the original device and make a backup of the disk. Then convert it to a normal disk, initialize it to MBR (or GPT, see other points), and then perform Low Level Format (e.g. using the Low Level Format Tool)

A): The newly purchased disk must be initialized before first use.

B): If the new disk is not initialized automatically, open "Disk Management", right-click on the desired disk and initialize it.
