How to connect my wireless keyboard (CK-440G) to phone without OTG jack.

Hi @03005,

Welcome to the HP Support Community.
 

Thank you for posting your query. I'll be glad to help you.
 

I understand you would like to connect your HP wireless keyboard CK-440G to your phone without using an OTG adapter.
 

The ability to connect the keyboard depends on the type of wireless connection the keyboard uses:

• If the CK-440G uses a USB wireless receiver (dongle), the phone must support USB OTG to communicate with that receiver. Without an OTG adapter or a built-in USB host port, the phone will not be able to detect the keyboard.
• If the keyboard supports Bluetooth, it can be paired directly with the phone through the Bluetooth settings without needing OTG.
   

To confirm the available option, could you please let us know:

• Is your CK-440G keyboard connected through a USB receiver/dongle, or does it have a Bluetooth pairing button?
• What is your phone model and Android/iOS version?

If the keyboard only works through the USB receiver and your phone does not support OTG, then it will not be possible to connect it directly to the phone without an OTG adapter or a compatible Bluetooth keyboard.

My keyboard does not have bluetooth support and it uses USB dongle and my phone supports OTG connection.

Hi @03005,

Thank you for the additional details.
 

Using an HP USB Wireless Keyboard with a Phone via OTG

Based on what you've shared, your HP keyboard uses a 2.4 GHz USB wireless receiver (USB dongle) rather than Bluetooth, and your phone supports USB OTG (On-The-Go).
 

Likely Cause

Whether the keyboard works through an OTG connection is determined by the phone's operating system and its support for USB Human Interface Devices (USB HID). While many phones recognize USB keyboards, compatibility is not universal and is outside the control of the keyboard itself.
 

What You Can Try

You can connect the keyboard's USB receiver to your phone using a compatible USB OTG adapter and check whether the phone automatically detects the keyboard.
 

Additional Information

• Android devices: Many Android phones support USB keyboards over OTG without requiring additional software. However, compatibility varies depending on the phone manufacturer, Android version, hardware, and how USB HID devices are implemented. As a result, some Android devices will recognize the keyboard immediately, while others may not detect it.
• iPhone and iPad (iOS/iPadOS): Support for USB keyboards depends on the specific Apple device, the version of iOS/iPadOS, and the USB adapter being used. Apple determines which USB HID devices are supported, so compatibility may vary.

Since USB OTG keyboard support is managed by the mobile operating system rather than the HP keyboard, we're unable to guarantee that the keyboard will function with every Android or Apple device. While many customers are successful using USB keyboards through OTG, the final compatibility depends on the phone's hardware and software support.
