问题 I have a barcode scanner works as HID device. Everytime a barcode scans it goes directly to windows keyboard, for example if I open notepad I can see the barcode typed there. As far as I know programmatically is it possible to to read HID data from your HID devices. But what happens if the user is already on a form with a text edit control? The scanned code will go inside the text box. Can you block incoming text and make a background-only processing? Can you explain the theory please? 回答1:

问题 I'm building a custom keyboard with stm32f103. My first trial with standard 8 byte works pretty well: 0x05, 0x01, // Usage Page (Generic Desktop) 0x09, 0x06, // Usage (Keyboard) 0xA1, 0x01, // Collection (Application) //Modifiers 0x05, 0x07, // Usage Page (Key Codes) 0x19, 0xe0, // Usage Minimum (224) 0x29, 0xe7, // Usage Maximum (231) 0x15, 0x00, // Logical Minimum (0) 0x25, 0x01, // Logical Maximum (1) 0x75, 0x01, // Report Size (1) 0x95, 0x08, // Report Count (8) 0x81, 0x02, // Input (Data

问题 The code below works fine for only one input device. Unfortunately I need to capture about 12 different HID devices (RFID readers), so I would like to know if does anyone know how to adapt the code to work with 12 different inputs? #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <errno.h> #include <fcntl.h> #include <dirent.h> #include <linux/input.h> #include <sys/types.h> #include <sys/stat.h> #include <sys/select.h> #include <sys/time.h> #include

问题 I need to interact with an HID device on Android. The problem is that i'm using Qt Android, and i'm not using Java UsbManager classes. Is there any C lib which I can link against in order to communicate with an HID device on Android without having to work with the Java API? I have found this: http://source.android.com/devices/reference/bt__hh_8h_source.html Which seems to be an header that defines HID communication but I can't find the associated lib. Any ideas? Thanks in advance 回答1: I have

问题 I've been struggling with this for a while now, trying all sorts of things to get this to work. It's my understanding that SetupDiGetDeviceInterfaceDetail is supposed to give the 1784 error the first time around because the sole purpose of calling it the first time is to get RequiredSize set to the right value. The second time it's called, it's supposed to actually work and give me a valid DeviceInterfaceDetailData structure. I'm not sure what is causing this to fail on the second call.

问题 I’m interested in setting up a machine (host A) and connect it to another one (host B) via usb or ps/2 such that host B will recognise host A as a keyboard. On host A an artificial neuronal network is running which generates dynamically input sequences. It’s important to me that host A can only communicate to host B in a “human” way, e.g. generating keystrokes and passing them to host B. As far as I know this is not possible with an usb connection since a host to host connection is not
