hid

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 operation of the HID? Thanx for your help! http://lxr.linux.no/#linux+v3.3/Documentation/usb/gadget_hid.txt

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 system cursor. Vladimir Keleshev I think, in wintab you can get the raw coordinates. At least in Python

I have device that is a USB HID Human Interface that sends keycodes to usb host when I press the keys and I just can't find a simple program that will dump all the input data that comes in my USB port? (with source code available of course. USBlyzer does it, but it's shareware) Justin Dearing Check out libusb and #USBLib Both are open sourse. #USBLib is a .net wrapper around the multi platform libusb. 来源： https://stackoverflow.com/questions/7373247/read-raw-usb-input-on-windows

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); MessageBox.Show("Hold Application Here"); Event Handlers for the scale private void DeviceAttachedHandler()

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 for a scanner with an RS232 interface. The problem is that HID "devices" send information back to the

I work on a project where I need get data of keyboard and mouse on a service. I also have to be able to send data to my device hid. To do this, I want use the usb host mode. When I get list of device, I can see a mass storage but no mouse and keyboard. After search, I have seen that usbManager don't return mouse and keyboard device. I have tried to change permissions (on /system/etc/permissions) whitout success). I have run the application USB Device Info and I see mouse and keyboard on linux device and not on android devices. I use android 4.2.2. Is it possible to get hid data of mouse (and
