(HID) Human Interface Device Communications in XP

I think you can add _GetRawInputDeviceInfo() call there with the device name handle and $iCommand set to $RIDI_DEVICENAME. According to the output of the device list on your machine there are a raw input port for keyboard and the remote raw input device entries. See if you still get same results. I think they should be different.

Edit: ... On a second thought, I think Microsoft just use your keyboard device as the remote's medium which makes me to think that you'll actually see the same device entry for two different - separated devices..

Edit2: But this can be interesting, you've posted it previously:

rid[0].usUsagePage = 0xFFBC;      // adds HID remote control
   rid[0].usUsage = 0x88;
   rid[0].dwFlags = RIDEV_INPUTSINK;
   rid[0].hwndTarget = this.Handle;

   rid[1].usUsagePage = 0x0C;     // adds HID remote control
   rid[1].usUsage = 0x01;
   rid[0].dwFlags = RIDEV_INPUTSINK;
   rid[0].hwndTarget = this.Handle;

   rid[2].usUsagePage = 0x0C;     // adds HID remote control
   rid[2].usUsage = 0x80;
   rid[0].dwFlags = RIDEV_INPUTSINK;
   rid[0].hwndTarget = this.Handle;

You can try one or all of them at once. All of them at once may require you to do the StringRegExpReplace loop as with the _GetRawInputDeviceList().

Ok I figured it out, I google search linked me to something similiar on AutoHotKey.

They had a cool tool that gave you all kinds of info on all your HID devices and monitored incoming data in a GUI.

Here's a link you might find it useful sometime: http://www.autohotkey.com/forum/viewtopic....asc&start=0

So to do this I only need two pieces of info VKey and VendorId.

Apperantly my remote always returns vendorID 81.

But I'm having trouble getting the vendorID. Heres what I've got but vendorID always comes back as 0

You need to assign to struct size to the cbSize member of the struct, then you'll use this size also in the function call:

I copied the vendor ID line to the keyboard section. But it return a vendorID of 0 for all keyboard devices.

I was told that technically keyboards don't have VednorID's but this other one somehow gets it.

I don't know if it helps you or not but I mostly converted the short script and UDF that works.

I only had trouble with a few lines.

EDIT- I meant my attempt to convert the AHK script that is able to get the vendor ID.

I'm attaching the original in a rar file.

So I guess it worked for you and you're happy?

Sorry I edited above, I meant to say I tried to convert that script but failed.

So that one won't run, and yours returns 0 for the VendorID.

MS sure makes this tough lol

Sorry lol. Now I understand who is the noob here lol >me<.

Try this one, I'll upload another corrected RawInput.au3 library to fix this stupid misunderstood. It's actually "|$RIDI_DEVICEINFO - pData points to an $tagRIDDEVICEINFO_* structure. and not $RID_DEVICE_INFO_* >< though you can see it from my last code snippet:

Read about HID and this post.

Also xbox 360 gamepad and wiimote are detected as hid peripherals.

Any chance to have something working for these ?

(xbox chatpad is one of most insoluble internet mystery)

thank you for any reply,

Hmm, I guess you can register this device to receive $WM_INPUT events from it. The usUsagePage and usUsage are obtainable by using _GetRawInputDeviceInfo(). If you'll get notified about the event from this device then $ilParam of $WM_INPUT is a handle to the this device and you can get it's data using _GetRawInputData($ilParam, $RID_INPUT, $pRI_HID, $iRI_HID, $iRIH).

There are also numerous examples in MSDN site about buffered raw input.

[ken82m]

Okay in the home stretch 99% working lol

Now the vendor id (81) is being returned from any remote buttons you would find on your keyboard.

For example enter, 1-9, arrows etc.

But things you wouldn't find such as channel up/down are coming back as 0, they should be returning 1118

[ken82m]

I uploaded the tools I found if you want to try them.

http://www.mediafire.com/?sharekey=0fddc05...2db6fb9a8902bda

The first one will should you a list of all HID devices.

And the second you can add UsagePage/Usage parameters and view realtime.

Depending on that output you can figure out if this will work and how you'll need to configure your script to make it work.

-Kenny

[Authenticity]

And the keyboard hook function is notified about these buttons? I think it's better to read the input into $tagRAWINPUT_HID structure because it suppose to catch everything the device is posting but it's quite not ""flexible" as a nice WM_KEYDOWN or WM_LBUTTONDOWN messages.

[ken82m]

Yeah, the keys are reported in your script just without the vendor.

I do see some devices with the vendorID 1118 listed as other in this tool with a usagepage/usage of 12/1

Meaning it's not a keyboard or a mouse. But yet the keys are returned in this tool watching 1/6

Strange

[Authenticity]

Strange behavior. Can yo go to one of this keys and post the value of the hardwareid value:

\\?\HID#HpqRemHidDevice&Col01#5&2f051232&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}
\\?\HID#HpqRemHidDevice&Col02#5&2f051232&0&0001#{4d1e55b2-f16f-11cf-88cb-001111000030}

It should be in "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum" and the rest after the \\?\. You can relate to the first key as:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HID\HpqRemHidDevice&Col01\5&2f051232&0&0000

Just replacing # by a \.

I'm actually testing this on my desktop, since my HP was returning some crazy data with the remote.

My desktop has an MS built reciever.

This one has 3 misc HID devices and 3 keyboard devices.

The three keyboard devices have a vendorid of 81

The three misc devices have a vendor id of 1118

Here are the three misc/1118 devices.

So it actually bring it to the beginning. You should get $RIM_TYPEHID when using $ilParam with _GetInputDeviceInfo($ilParam, $RIDI_DEVICEINFO, $tRIDI_HID, $iRIDI_HID) or if I'm wrong and it can highly possible you can modify the previous script. The only thing you need to query is 'dwType' of the $tRIDI_HID struct. It can't happen that both contain the same $RIM_TYPE*.

Edit: And what about the main problem of distinguishing between the devices?

Edit2 OK, so it's by no mean should be $ilParam there, though you can get hDevice by using this $ilParam handle to a $tagRAWINPUT_* struct.

_GetInputDeviceInfo($hDevice $RIDI_DEVICEINFO, $tRIDI_HID, $iRIDI_HID), the rest is known.

type comes back as 1 for all buttons on the remote and the keyboard

the 1118 buttons come back with a hdevice of all 0's.

But I don't think that helps, that's probably true for any non keyboard device right?

[ken82m]

I'm glad your getting something out of this so I don't feel like I'm just driving you nuts lol

I don't have that one on my desktop, the other id's are it's equivelent
