问题 We have some HID devices (touch digitizers) that communicate with an internal R&D tool. This tool parses the raw feature reports from the devices to draw the touch reports along with some additional data that are present in the raw feature report but filtered out by the HID driver of Windows 7 (eg, pressure data is not present in WM_TOUCH messages). However, we have started working with some devices that may have different firmware variants, and thus that do not share the same ordering or

问题 Context: I'm using Qt 5.9.3 on Windows, building for MinGW 32-bit. The Qt part is a side issue though - the problem seems to be with MinGW. The version of MinGW is 4.3.0, supplied prebuilt as part of the Qt installation. I'm building a library which talks to a USB device over HID. Everything compiles fine, but it fails at the link stage with ./..\..\object\debug\usb_hid_device.o: In function `ZN8MyApp3USB5Win3213getDevicePathB5cxx11Ell': <MYPATH>/../../source/win32/usb_hid_device.cpp:99:

问题 Attempting to use the chrome.hid API for a Chrome Packaged App we ran into an issue where our USB devices are in the ignore/blacklist. What is the process for ChromeOS to get all of our devices removed from the blacklist? See this post for reference: HID compliant device will not enumerate using chrome.hid API on ChromeOS 回答1: This isn't a Chrome OS specific problem. This device is in the Linux kernel's hid_ignore_list because it doesn't implement the HID protocol correctly. Given that the

问题 I want to set up my embedded application as a HID device, with a separate process controlling the HID interface to allow dynamic connections to a PC. There seems to be many people out there that have done it, but I would like to do is: a) Understand how to configure my build (Freescale i.MX Linux using ltib) to include the USB APIs and includes in my build (ie g_hid.h). b) Where can I find an example application which does something like move the mouse about the screen to demonstrate the

问题 I am trying to write a python script on Windows 7 to interact with my Wacom Bamboo Pen tablet. Wacom recommends using the WinTab API, and it works fine, but not for my application. I don't want the Wacom tablet to act as a pointing device (as in, it should not move the cursor). All I want is raw x, y data from the device. What is the best way to implement this? Do I have to write a different driver for the tablet to allow this? Or can I modify the existing Wacom driver to not affect the

问题 I have a bar-code scanner with USB interface, so it appears as an HID. There are reasons why I must breakpoint on the first character. That brings my Delphi IDE to the front, it stops on the breakpoint and the rest of the bar-code is injected into my code as if it had been typed front the keyboard (which, in a way it has, as the USB scanner is just another HID). Is there any way to avoid this? Or to add an initial check as to the source of the input? It annoys me so much that I am now looking

问题 I am using Mike O Brien's HID Library to connect to digital scale, Device opens successfully then displays device attached & removed messages perfectly. But only runs OnReport for about 20 times initially After Inital approx 20 runs on OnReport it never runs again, unless I remove usb cable and re-connect. My code is below if (scale.IsConnected) { scale.Inserted += DeviceAttachedHandler; scale.Removed += DeviceRemovedHandler; scale.MonitorDeviceEvents = true; scale.ReadReport(OnReport);

问题 I am trying to make some code regarding USB HID devices. I have found an article about Bluetooth programming which uses Game Kit Framework. Now I'm looking for some tutorial or maybe some code to work on connecting HID device via USB. Where should I look? Is Game Kit the right way? Is it difficult to implement communication between iOS and HID device? 回答1: You can use IOKit for USB, but it's a private framework on iOS - so it depends if you want to deploy to the App Store. Here is the USB

问题 Using the library in this link http://www.blog.kslemb.com/doku.php/en/projects/globx/java_hid I have been modfied this code to write on a HID terminal if (HIDHandle.equals(WinBase.INVALID_HANDLE_VALUE)) { return HID_DEVICE_NOT_OPENED; } /* Write Feature report */ boolean Status=Kernel32.INSTANCE.WriteFile(HIDHandle, buffer, (int)buffersize, null, null); if (Status == false) { debug("Write File: " + getSystemError(Kernel32.INSTANCE.GetLastError())); return HID_DEVICE_TRANSFER_FAILED; } else {

问题 I have this USB Relay: http://www.ebay.com/itm/5V-USB-Relay-2-Channel-Programmable-Computer-Control-For-Smart-Home-/141097843081?pt=LH_DefaultDomain_0&hash=item20da163989 Al I need is to send close/open to the device (to turn on & off an LED light) How can I do that using C# or C++? Thanks Boaz 回答1: Here's what you need (tested on Linux) : HIDAPI from http://www.signal11.us/oss/hidapi/ USBRELAY from https://github.com/darrylb123/usbrelay/blob/master/README.md Use it like : usbrelay ZG4HU_1=1
