Hid Keyboard Device Driver Vista
If you have a laptop or another generic keyboard then please the built-in keyboard or generic keyboard to follow these steps. If your mouse does not work then please try another USB mouse, since we really need that one for this tutorial. I can´t sign-in without a keyboard. This can be a huge problem if your keyboard and other keyboards are not working. However if you have a working mouse then this is not a real problem, Microsoft has added an on-screen keyboard to the sign-in screen which you can use to enter your password. Onscreen Keyboard Animated The “Wait a few minutes trick” Their is a possibility that Windows just simply has to download a new driver to run the device on your system. This is what I call the “Wait a few minutes” trick.

Because Windows Update will begin scanning your system and determine which drivers need updating and automatically downloads them Manually Installing Your Keyboard The next step we’ll have to take is to manually install your keyboard on your system. Please read these instructions carefully and follow them. Right-click the Start button and choose Device Manager. Once in Device Manager locate all devices with a yellow exception mark in front of them. In case of not working keyboards they are most-likely located under Human Interface Devices (HID) and keyboards. Under keyboard s right-click a keyboard with a yellow exception mark. I have a laptop, HP That’s a month old.
It came installed with 10, until yesterday, ither than being slow as molasses compared to my normal laptop, it’s been fine for kids use. Today, the I key, enter and mouse are all that seem to work. I used USB keyboard to get in amd check drivers, no exclamation marks, but went ahead and had it check for updates, it got to the ps/ keyboard, updated “correct” driver, and now nothing works. Can’t access the ease of use icon at login screen, as it just doesn’t pop up, no matter how many times I click on it.
The solution recommended here (to get a keyboard to work again) will not work in my case because “Keyboard” no longer appears in my Device Driver list. I found a way to display the hidden drivers and Keyboard came back on with the yellow yield sign. Believing the driver was corrupted, I tried updating – but Win10 replied I had the latest driver. So I thought I would uninstall then reinstall. Did the uninstall, and now Keyboard will not appear at all in my Device Driver list.
So I am exploring ways to reinstall the driver manually – including trying to find a driver – but I have no idea if this is the problem. It may not be. Anyone else experienced this?
I'm trying to develop device independent library for barcode scanners, it has to be working in windows environment. I've done some research in this field, afaik most of the solutions of this problem are depending on specific device VID&PID (RawInput @ filter by vid&pid string), in my situation this is inacceptable, because i'm trying to develop a device independent solution, which will be working with any USB-barcode scanner.
Actually this thing is quite challenging, for me atleast, here are exact requiriments. Also i can't ask user to hot-plug device (in that case i could've just detect plugged device and extract it vid/pid). Also i can't use VID&PID database of devices. In general i can't use vid&pid at all actually. Also i can't in any way reprogramm barcode scanner, unless it's done from my programm (maybe i can send some barcodescanner-specific IOCTLs which will make it answer to me?). Currently i'm going to use solution proposed in this question: Also i have seen commercial library (which is offcourse comes without any sources and any info about how it's implemented, but considering they have'd some word 'Perfomance counter' in their changelogs, i guess they used solution in the link above), which implements this functionality, but it doesn't work in x64 systems. Probably either because of messy code or beacause it probably uses some kind of filter (mini) driver.
It's crypted and i can't redistribute it. My exact question is: Is there any way to determine that this HID keyboard is in fact not a keyboard, but a barcode scanner? I've seen on Win 7 x64 that it connects as Barcode scanner, not keyboard (this was a system bug, or sort of). Exactly what i'm doing now:. Reading input by RIDINPUTSINK. Distinguishing all input by vid&pid of device.
Putting all input to separate buffers and collecting barcodes from buffer when VKENTER shows on buffer. What i'm currently going to do:. Read input by RIDINPUTSINK. Start timer for specific device and if next symbol is VKENTER - stop timer. If timer exceeds 50 ms limit - off it and drop all further device input. If device will successfully read sequence of characters from first symbol to VKENTER - extract device VID&PID/handle and work with it in more convenient way (without timering). I'm developng it on C, pure WinAPI, it will be a DLL library, and got to work in Windows XP, Vista, 7, 8 on x32-86 and x32-64 architectures.
UPDATE 0: Just found that barcode scanner have their own usagePage and usage in USB specs: According to this document USB Barcode scanner have UsagePage 0x8C and Usage 0x02. Unfortunately i've failed using it as RAWINPUTDEVICE.dwUsage and RAWINPUTDEVICE.dwUsagePage. Probably because system install it's usb keyboard driver on top of it and in user mode it is indistinguishable from real usb keyboard. Probably those values are usable in kernelmode environment (one of the options is to develop hid filter driver).
