Add Peripheral Detection

[CodeWithShreyans]

Can there be detection for keyboard, mice, headphones, RGB controllers, fans, etc.?

[L3tum]

Yep! Though it'd be quite a bit of work, especially since I'm not sure about how well the various Linux systems will support it. Windows is easier in that regard, I may start with that.

[caunt]

I'd tried to get my keyboard manufacturer from WMIC (also device manager) but it just says "Standart keyboard". Assuming there will be some issues with peripherals. Also looking for any another way to get USB device manufacturer.

[CodeWithShreyans]

Maybe assistant applications for high-end peripherals install a special driver which has the details?

[caunt]

Nvm i found it in PnP device list in WMIC. Seems to be able to make USB devices list easly 😃

[caunt]

Get-PnPDevice | ForEach-Object { Get-PnPDeviceProperty -InstanceId $_.InstanceId | select KeyName, Data }

Seems good as it prints all PnP devices and their properties (hardwareId, manufacturer, product, etc)

[L3tum]

Interesting that it's available as a powershell module but not in the WMI Entity (PnPDevice). At least to my knowledge.

I'll try to find the source code for that command, maybe I can reverse engineer it. I'd like to avoid as many calls to console commands as possible (and I already dislike MacOS as a result).

[caunt]

I'd like to avoid as many calls to console commands as possible

And also script that I sent works only in latest versions of windows. So we should find right way to get PnP devices information.

Get-PnPDeviceProperty method was added only in windows 10.

[CodeWithShreyans]

All the ls... tools in Linux are an easy way to get hardware info. lsusb shows all USB devices on Linux. lsusb -v gives an extremely detailed output for the devices. lsusb -t -v shows it in a tree of which device is connected to which USB Hub. lspci gives info on pci devices. lspci -v gives verbose output and lspci -vv is even more verbose. lspci -mm and lspci -mm -v give a structured data output. lsblk -S gives info on drives.

[L3tum]

@caunt Good to know, that means the whole thing becomes more complicated :( Fallback would still be to access the registry, though I'd like to avoid that at all costs.

@DestroyerXyz Are the lsXXX tools guaranteed to be present on any Linux system? Afaik most docker images don't have it, for example. I'd like to be as barebones as possible.

[CodeWithShreyans]

Most Linux systems do have the ls... tools

[L3tum]

I've found a few libraries for Windows, but they all only seem to detect my Headset, not even the Xbox Controller that WMI offers, as they go directly through the USB Hub and any devices that are already in use can't be queried...or something like that. Windows seems to be more tricky than I thought. The Registry method also only found my headset and nothing else, which is worrying. I may lock it behind Win10 for now and use Get-PnpDevice, as much as it pains me.

[CodeWithShreyans]

I don't have many devices but I tried lsXXX on a wireless mouse and a webcam and it worked.

[L3tum]

The Get-PnPDevice "Source code" (as available through Powershell) can't be used. I'm not sure if something's missing or if it's obfuscated. It's apparently also part of Windows, and not Powershell, and as such isn't open source. Yay.

I'll start using this command and locking it behind Win10. Linux seems okay with the lsXXX commands. Maybe I'll do some manual /sys/ querying if I got time.

[L3tum]

https://github.com/L3tum/HardwareInformation/commit/6183165ecbdf0ff2ce708946cad674153cea6b02 It's so janky, I love it.

[L3tum]

Seems good enough for Windows for now. Unfortunately the Manufacturer doesn't seem to be available or I haven't found it yet. Maybe DriverProvider? Though that is Microsoft most of the time, so not really the Manufacturer.

I'm also not sure whether to strip the Hubs from the list. I already removed most of them, but those two seem to be my front-panel IO and the hub of my Mainboard (ASMedia for my ASUS afaik), which may be interesting to have.

Here's an example from my PC:

[CodeWithShreyans]

You can add a long list of general manufacturers and check if one of them is present in the Name or DriverName (or DriverProvider)

[CodeWithShreyans]

You can also search Google with the DriverName to find the manufacturer using the API (https://developers.google.com/custom-search/v1/overview) if the list way doesn't work, for ex., I searched google for "C922 Pro Webcam" and found that the Manufacturer is Logitech.

[CodeWithShreyans]

Another API (https://rapidapi.com/blog/lp/google-search-api/?utm_source=google&utm_medium=cpc&utm_campaign=Alpha_100831832819&utm_term=google%20search%20api_e&gclid=CjwKCAjwoc_8BRAcEiwAzJevte2kSkfNOqYRMWQrEW674Jtjb5_Z7IaiJzb2Eze-se1v60TEYpSIahoC9LkQAvD_BwE)

[caunt]

That's strange because I saw keyboard/mouse "manufacturer" and "product" fields on my PC with powershell script. I'll show it in a few hours.

[L3tum]

As far as I've understood it (which basically amounts to 2 hours of scouring MS docs yesterday), these values can, but don't need to be, set by the device and/or the driver's INI file. It'd definitely be cool to have an example so I can use these as optional values or something to that extent.

[L3tum]

Ah, found it. DEVPKEY_Device_Manufacturer Logitech G series. I need to walk the Device Tree to get to that. Lemme see if I can implement that.

[caunt]

My wrong. Now I see a lot of "DEVPKEY_Device_Manufacturer" key names in PnP device propertiers ... but all of them something like "Intel" or "Microsoft" that does not meaning anything helpful for USB device.

My keyboard/mouse have just "Standard USB Host Controller" value in that property.

[caunt]

Also I thought I saw any "product" property but that false.

[L3tum]

@DestroyerXyz and @caunt got me thinking though. I'm now using the "optional" (I guess) properties of Manufacturer and name and also do some matching on those, as well as DriverProvider, to get the best possible data.

Additionally, I've implemented a T4 Template to fetch the latest USB Vendor and Product IDs from http://www.linux-usb.org/usb.ids that are then mapped to the IDs provided in DeviceID.

I'm still gonna do some optimizations as right now those lookups take ~200ms alone on my machine and that's...not good.

Result (Don't worry about the weird spaces, those are due to copying it from the console):

Found possible solution for windows 7: Get-WmiObject Win32_PnPEntity - output.txt (tested on virtual machine, so there no normal keyboard/mouse/etc entries)

EDITED: solution with screenshot that i deleted was not for windows 7.

[caunt]

Lol I realized that Win32_PnPEntity class available on both windows 10 and windows 7 (even may be lower versions). So we can focus just on that.

EDITED: Nah its available even from Windows 98 - https://www.it-visions.de/scripting/WMIReferenz.asp?C_Klasse=Win32_PnPEntity

[L3tum]

I've optimized the accessor quite a bit now. Funny story though, the ThreadAffinity stuff is now broken in the linked pull request (#24). No idea why, literally didn't change anything (the changes you see there was me trying to fix it). Would be cool if any of you could try out the branch to see if it's some problem with my PC or if .NET just decided to miscompile that class now.

[caunt]

I'll test in few hours 🙂

Branch HI-21_pnp_devices:

https://pastebin.com/JJFZxR2h

[L3tum]

Thanks! Seems like my PC was just a bit...fucked yesterday. Seems to work correctly today as well.

That key being null seems interesting though, I'll need to investigate that.

[caunt]

Tell me if you have not this null as I am. I can make time to debug it myself.

[L3tum]

If you've got some time that'd be wonderful. My best guess is that it's some specific USB device that results in one of the values being null. I've already gated every key behind an is null but maybe I've missed one.

[L3tum]

@DestroyerXyz I've just pushed some changes to the linked PR that now implements USB information on Linux. Would you be so kind to test it out? I don't really have a Linux system on hand where I can test USB stuff on (VMs don't support that kind of passthrough easily apparently). I'm particularly interested if some of these values actually work for you; for example Class always either contains "Hub" or "Vendor Specific Class" for me.

It seems like lsusb also already reports vendorName and productName, but parsing that would be a bit of a pain so I'm going via the lookup (which uses the same list :P) and the performance difference probably won't matter.

[CodeWithShreyans]

Yes, I will test it in a bit.

[CodeWithShreyans]

I am not sure how exactly to test the app from PR. Can you tell me the steps?

[L3tum]

Ah, sorry. You can checkout the branch and run it with dotnet. Alternatively I could provide you with a standalone app...I think I'll do that. Maybe for the future I'll implement some sort of artifact upload from the automatic jobs

I can also do a Mac test if you want. I just installed a macOS VM. The test may be a little inaccurate because of the VM.

Thanks! Mac is good so far, I haven't changed anything there yet. Not sure I'll support it with this (for now) as, just like everything else on the Mac, seems to be a PITA to implement.

@caunt I think latest PR push also has fixes for the bug you encountered. Apparently I wasn't really dilligent in checking for properties of a dictionary.
