Daemon not working with emulate Surface Dial

[2ndBillGates]

Describe the bug

Hello Sir,

I'm trying to combine your project with this, it's a android app to emulate Surface Dial bluetooth HID device. It works great on Windows. (Meaning I don't own a Surface Dial)
https://github.com/tumuyan/Kontroller
I know it's a old project of yours but I want to make it available to more users.
Thank you for making it possible.

1. Surface Dial is not recognise
When I was running the daemon first time, it stuck at "haptics worker is waiting..."
I guess the daemon does not recognise the Dial (Phone) is paired and connected
because your project rely on reading the bluetooth device name "Surface Dial"
While my phone bluetooth hostname is something else.
then I change it to "Surface Dial"
Now it recognise

haptics worker is ready
Dial Connected

2. Error when the Dial sending commands
but then, whenever I try to use the Dial
the daemon gave me

Started
haptics worker is waiting...
haptics worker is ready
Dial Connected
Unexpected haptics worker error! HID API Error: Failed opening hid device
the haptics worker died!

I think it's because of "hidraw4" "uinput" is not given permission.
Despite the udev rules was set.

then, I run

sudo chmod 666 hidraw4 & uinput

this time it gives me another error.

3. Error at .upwarp()

haptics worker is waiting...

Happened to see this before I was about to head off to bed...

That's yet another permissions error, and those extra recv errors are just downstream errors (other threads dying because one thread died).

Check the source of the error in the code and try to deduce which file / perms need to be changed.

Not sure if I'll be able to be much more help, but best of luck!

Thank you for the tips, I'm debugging myself.

/dev/hidraw4 (I confirmed is Surface Dial)
I've found that /dev/hidraw4 cannot access by user except root

If I run cat /dev/hidraw4 | xxd
without sudo, it gives me permission denied

When I run it with root, and move the wheel
I received input

ahhh. I fixed that issue by udev rules.
But now I get another error from Haptics

I'm trying to find a way to disable haptics module

surface-dial-daemon 
Started
haptics worker is waiting...
haptics worker is ready
Dial Connected
Unexpected haptics worker error! HID API Error: hidapi error: No such device
the haptics worker died!

Might have something to do with the hardcoded hwid values on this line:

surface-dial-linux/src/dial_device/haptics.rs

Line 61 in b484872

let hid_device = api.open(0x045e, 0x091b).map_err(Error::HidError)?;

I managed to make it working, since I'm not so sure what line "64~76" codes are for from haptics.rs.
Now the daemon won't exit without error.

The scroll is a little bit too sensitive though. especially for "Zoom" & "Media"
Scroll (Fake Mutli-touch) works perfectly.

I'm not sure why you put KEY_SHIFT in volume mod, so I removed it.
