Hello, i've been strugling with this for some time now but finaly found the solution.
You not only have to edit the irbus.inf file, but also input.inf, keyboard.inf and medctroc.inf located in the windows inf folder.
This are the lines i added to the files
to input.inf
[MICROSOFT_KBD]
%IRBUS\VID_045E&PID_006D.DeviceDesc%=HIDIR_Inst, IRBUS\VID_1784&PID_0006 ; HP
[HIDIR_Inst_DeviceID.Addreg.NT.HW]
HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Remote Controls","HID\VID_1784&PID_0006&COL05",0x00000000,"" ; HP
[strings]
USB\VID_1784&PID_0006&Col01.DeviceDesc = "EHome Infraroodtransceiver"
irbus.inf
[MicrosoftHw]
%USB\VID_045E&PID_006D.DeviceDesc%=IrBus_V2, USB\VID_1784&PID_0006
[ControlFlags]
ExcludeFromSelect=USB\VID_1784&PID_0006
[Strings]
USB\VID_1784&PID_0006.DeviceDesc="eHome-infrared-receiver"
keyboard.inf
[MICROSOFT_KBD]
%HID\VID_045E&PID_006D&COL05.DeviceDesc%=eHome_Keyboard_Inst,, HID\VID_1784&PID_0006&COL05 ; HP
%HID\VID_045E&PID_006D&COL06.DeviceDesc%=eHome_Keyboard_Inst,, HID\VID_1784&PID_0006&COL06 ; HP
%HID\VID_045E&PID_006D&COL07.DeviceDesc%=eHome_106_Keyboard_Inst,, HID\VID_1784&PID_0006&COL07 ; HP
medctroc.inf
; List of MCE remote controls
HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Remote Controls","HID\VID_1784&PID_0006",0x00000000,"" ; HP
(only the black text has to be added)
This seemed to do the trick and made the remote fuly functional.
Let me know if it works for you.
Grtz Wailer.
