Bug Report: MCO FKB-R252 Trackball Keyboard - hid-multitouch error (HID_DG_BUTTONTYPE out of range)

Hardware Support

Hello,

I am reporting an issue with the MCO FKB-R252 (a combination keyboard and trackball). While the keyboard functions correctly, the trackball is completely unresponsive on Linux (tested on Zorin OS 17 / Ubuntu-based).

Device Information:

  • Product Name: MCO FKB-R252
  • USB ID: 24d3:7139
  • Current Driver: hid-multitouch

Symptoms: The kernel seems to misidentify the trackball as a multitouch device. When the trackball is moved, dmesg reports the following error repeatedly: hid-multitouch 0003:24D3:7139.000C: HID_DG_BUTTONTYPE out of range

Request: It appears the hid-multitouch driver is failing to parse the HID report from this device. Could this device ID (24d3:7139) be added to a quirk list to be handled by hid-generic or have its report descriptor fixed? This device works perfectly as a standard HID mouse on Windows.

Thank you for your help in improving hardware compatibility.

Welcome to the Forum!

Did You tried it on Zorin 18, too? Did You tried it with switching between Wayland and Xorg? Are Secure Boot and Fast Boot in BIOS disabled? Is Fast Start-Up in Windows disabled?

Maybe this thread can help you? But it is about ubuntu 24, so I'm not sure.

Hello Mr Jixr,
We found this information from this forum, because we are the keyboard maker from Taiwan, if you want to try to help us to solve this specially issue, may we can send the keyboard receiver unit firmware to you for upgrade it, then may it can solve this problem as you high-light in here. so if you want to do it, could you please send a email to me via [Email Address Redacted by forum moderator], then we can send a USB receiver dongle to you for upgrade it.

@lawrencetsai,
As an engineer or representative of Lexking, it may be far better to provide any needed firmware upgrades through the Official Lexking Website. Similarly, direct customer communication can also be managed on the Official Website.
Both of these actions can reassure the end user that their contact point is legitmate.
Further, supplying a Firmware blob is to supply direct programming to a persons computer and this must be handled directly through a verifiable source.

To this end, I have removed the contact email from your message in order to allow any other user to safely redirect to the Official Lexking Website rather than seeking to resolve issues through another persons personalized email.

If you like, you can link to the official download link at Lexking for the end users convenience.
