uchroma -l returns empty about uchroma

Yep, can confirm same issue on Razer Blade Pro 2017

[jramapuram]

Same issue on Arch for me

[hyperb1iss]

Apparently something is different on the new Stealths.. I'll see if I can get my hands on one.

I'm running a GTX1060 2016 Skylake RB, not a stealth

[jtmkrueger]

I'm having the same issue on the new Pro 17"

[brad-decker]

Add another confirmation for razer blade pro 2017

[jacobc-eth]

Any word on a fix for newer laptops?

[hyperb1iss]

Unfortunately not, I haven't been able to get my hands on any of the 2017 laptops and not for lack of trying. If you're able to capture a packet trace in Windows while using Synapse, that could be very helpful.

[jramapuram]

This is also happening on my 2016 gtx1060 razer blade

[jtmkrueger]

@cyanogen I have dual booting setup on my 2017 razer blade pro. Is there any documentation regarding what you want as far as a packet trace? I'm more than happy to provide one, I'm just not sure how to go about getting it. I'll apologize in advance for my lack of Windows knowledge.

[hyperb1iss]

There's an open pull request that brings in support for at least the new Blade. It may be as simple as adding the device to laptops.yaml.

[splushii]

I tested with the current version. The issue seems to be resolved for Razer Blade Stealth (Kaby Lake). Not sure about 2017 models so I am not closing this.

[keponk]

@cyanogen I've got a Razer Blade 2017. I attempted to copy the laptop.yaml file from the pull request into my installation via yaourt in Arch. No changes, after doing the change and rebooting the uchroma -l command still throws nothing.

If you give me instructions on how to collect packet trace data from windows I'd be happy to produce it.

Thanks for the work on the project!

Just like to add that I have the same issue, even after adding the pull request.

If it helps,

I tried to track down the issue in device_manager (why it reports no devices).

parent = self._get_parent(devinfo.product_id)

devinfo.product_id == 0x0224
parent == None

if parent is None:
                continue

So then I tried to look at why _get_parent was failing:

        pid = "%04x" % product_id
        self._logger.info("pid == %s", pid)

        devs = self._udev_context.list_devices(tag='uchroma', subsystem='usb',
                                               ID_MODEL_ID=pid)

pid == 0224
devs == <pyudev.core.Enumerator object at 0x7fcd2cf2c908> but appears empty

Then I removed the tag='uchroma' and then I get:
DEVTYPE == usb_device

Now I instead get this error:

Considering the tag failed and the permissions are failing, this leads me to udev. Your udev rules must not be working?

ACTION=="add|change", SUBSYSTEM=="hidraw|usb|input", ATTRS{idVendor}=="1532", IMPORT{builtin}="hwdb --subsystem=usb --lookup-prefix=uchroma:"
ENV{UCHROMA_DEVICE}=="?*", TAG+="uchroma", TAG+="uaccess"

[jblankfeld]

Hi, I'm having the same issue as above.
Does anybody know how to fix the udev rules ?

same issue on blade stealth 13" 2020 (no devices show with uchroma -l)
