Touchpad & Bluetooth don't work on laptop

Description (last modified by eugenia)

I have this other laptop (DELL 5480) that I tried Haiku-nightly on tonight, and it booted great. Absolutely everything works on it, including wifi, expect for the touchpad and the Bluetooth. The touchpad is obviously the bigger concern between the two.

I connected a USB mouse, and that worked fine. The keyboard also works fine. It's just that the touchpad doesn't register at all.

In case of the Bluetooth, it sees that it's a bluetooth device (it loads the B logo in the bluetooth app), it tries to start the service, but it says that it failed.

I'm attaching here lsusb and lspci from my Kubuntu partition on that machine. The device name for the touchpad is weirdly called under X11's xinput: DLL07D0:01 044E:120B

The touchpad "DLL07D0" appears to be an ALPS I2C device according to https://www.driveridentifier.com/scan/alps-i2c-hid-device/download/1096433241/CD3BCF37E3F44A42AC80142D140A4EFA/ACPI%5CDLL07D0

Our I2C HID driver is incomplete, I don't know if it can discover devices from the ACPI device tree, and also if it needs special handling for ALPS devices or if they follow the HID standard. I think it is also not included in nightly images yet?

If you want to help testing this driver you may have to make some changes to Haiku sources to build a custom disk image including it, are you willing to do this? If so we can provide instructions for it.

Bluetooth is generally unsupported. The best you can get with the current code is pairing with some devices, but there are no drivers to do anything with them once they are paired, so it is quite useless at the moment.

Thank you. If the driver is going to be included in future nightlies, I can wait for it to test again. Currently I can't develop, as our home is in disarray due to moving back to Europe.

still no luck but slightly different hardware. Adding here since it's most probably related. Also, bluetooth and touchpad seem to be related as they are on the same chip from what I gathered.

My hardware:

Platform

StarLabs StarBook, Intel 11th gen platform

Bluetooth

Bluetooth from Devices app:
usb/subclass	0x1
usb/protocol	0x1
device/id	0x26
device/vendor	0x8087
usb/class	0xe0
device/flags	2
usb/id	36
Device name	AX201 Bluetooth
device/driver	bus_managers/usb/device/driver_v1
Manufacturer	Intel Corp.
Driver used	unknown
Device paths	unknown
device/bus	usb
device/pretty name	USB device
Class info	Wireless (Radio Frequency, Bluetooth)

Touchpad

most probably this one, not recognized:
