QueryDevice fails with error code 1167 (0x48F, ERROR_DEVICE_NOT_CONNECTED)

[d8ahazard]

Trying to loop through all the various GUIDS and see if anything is connected, and I get this error with every query to the API.

Here's the code I'm running:

var props = typeof(Devices).GetFields(BindingFlags.Public | 
			                                              BindingFlags.Static |
			                                              BindingFlags.FlattenHierarchy)
				.ToList();
			Log.Debug("We have " + props.Count + " props.");
			foreach (var prop in props) {
				var guid = prop.GetValue(null).ToString();
				if (guid != null) {
					var guidVal = Guid.Parse(guid);
					Log.Debug("Prop: " + guid);
					try {
						Log.Debug("Checking GUID validity...");
						var valid = Devices.IsValidId(guidVal);
						Log.Debug("Not dead yet.");
						if (valid) {
							Log.Debug("Querying...");
							var info = await _chroma.QueryAsync(guidVal);
							Log.Debug("Still not dead...");
							if (info != null) {
								Log.Debug("Device discovered!: " + info.Description);
							} else {
								Log.Debug("Device is null...");
							}
						} else {
							Log.Debug("Guid is invalid.");
						}
					} catch (Exception e) {
						Log.Warning("Exception: " + e.Message);
					}	
				}
				
			}

And here's the log output:

Instead, I'd obviously expect to get deviceinfo and the option to check if they're connected.

Any suggestions?

I'm checking that the Chroma SDK is installed before, and those checks return fine as well:

Error code 1167 (0x48F) is ERROR_DEVICE_NOT_CONNECTED (reference).

Are the devices you are querying connected to the system?

Regardless, the SDK shouldn't throw an error code if an unconnected device is queried, so that is most definitely strange.

[d8ahazard]

They are not, I've only got the emulator currently, I was just testing the method functionality.

I get the same results on my machine.

A query on Blackwidow which I have connected works fine. A query on Blade Stealth which I do not have fails with the 1167 error. This at least confirms the suspicion about it failing on devices that are not connected, but it's not the behaviour I'd expect from the SDK.

I don't have an official channel to Razer for questions at the moment, but I'll see if I can get a response from the community Discord (which has some Razer staff on it).

Ok, thanks. As long as I can "do something" to validate device connectivity, that will work. In a perfect world, the chroma emulator would be detectable as well...

Also, FWIW, if the SDK wasn't throwing an exception on a disconnected device (or you ignore the exception), the attached code can be used to enumerate all device GUIDs from Devices and check for connectivity, possibly to implement #145

If they come back and say that the error is intended, I'll update the library to detect that and return the struct with Connected set to false. That way the caller (users of the library) don't have to manually handle this error case.

Looking at the SDK reference, I think this is the designed behavior...

They did at some point change the Connected on DEVICE_INFO_TYPE from being a boolean to being a DWORD. Presumably it was around the same time they changed the behaviour for devices that are not connected. But hopefully I can get some official word on it as well, there doesn't seem to be a changelog for the SDK.
