问题 I am trying to perform read and write operations on a pen drive. Details: Vendor ID: 8564 and Product ID: 1000. It is a Transcend JetFlash mass storage device. I am keen to know that whether it is possible to achieve a read/write on a pen drive. If it is, then is it going to happen the way I have tried in the code provided below. I have learnt the methods to get the device id, product id and endpoint addresses. This is what I have implemented. Here the device is getting acknowledged and

问题 I have try to get data from device (USB thermometer), following this docs https://www.npmjs.org/package/usb, but I have not any result. For getting themperature data from device, I should send the data like that 'd\n'. This is my code: var usb = require('usb'), term = usb.findByIds(65535, 2); term.open(); var endpoints = term.interfaces[0].endpoints, inEndpoint = endpoints[0], outEndpoint = endpoints[1]; inEndpoint.transferType = 2; inEndpoint.startStream(1, 64); inEndpoint.transfer(64,

问题 How can we query connected USB devices info in Python? I want to get UID Device Name (ex: SonyEricsson W660), path to device (ex: /dev/ttyACM0) And also what would be the best Parameter out of above info to be used as identifying the device whenever it's connected again? (UID?) I am working on Ubuntu 11.04. ATM I have this code (using pyUSB) busses = usb.busses() for bus in busses: devices = bus.devices for dev in devices: print repr(dev) print "Device:", dev.filename print " idVendor: %d (0x

问题 I am having problem figure out how to use libusb, I put "libusb-1.0.18-rc1\libusb" in include directories (using Visua Studio), but it doesn't work. Can anyone enlighten me. Thanks a lot! error message: 1>test.obj : error LNK2019: unresolved external symbol _libusb_exit@4 referenced in function _main 1>test.obj : error LNK2019: unresolved external symbol _libusb_close@4 referenced in function _main 1>test.obj : error LNK2019: unresolved external symbol _libusb_release_interface@8 referenced

问题 I am attempting to write a linux driver for a printer. I have run USBSnoop on windows XP and obtained the log. In this log it sets wMaxPacketSize to 1026. After i set the interface i get the response of 75 bytes. If i set it to 64 (in the lsusb output) i obviously only get 64 bytes back. My issue is on a bulk transfer to/from the device i get timeouts. I think i have the same problem as here: http://libusb.6.n5.nabble.com/libusb-bulk-transfer-return-timeout-error-and-transferred-set-to-0

问题 I am using escposprinter python library for printing my data in thermal printer. It depends on pyusb. the library is working fine in linux . While in windows 7 ,i get the it have some issues. Here are output i get.

问题 I'm writing a small C application to run on my (Linux) QNAP NAS that will talk to an Arduino (I have no difficulty with any of the USB code for the arduino). (The arduino has a trusted application on it that accepts text commands via USB serial.) My wish was to find it using the USB vendor/product IDs (only half implemented at the moment). What I have so far (see below) works quite nicely in that it does find the device. // runs on NAS #include <stdio.h> #include <usb.h> main () { struct usb

问题 After reading a little, I am concerned that my 32-bit Delphi application will not be able to use libusb 64-bit driver on Windows 7 and other 64-bit Windows systems, and that it will not be able to talk to my custom hardware device on those systems. Is this true? If yes, is there some workaround? Am I missing something in this picture? 回答1: On libusb 1.0 with the WinUSB backend (Microsoft driver included with windows) we have no problem to communicate with it from an x86 app (Managed c++

问题 How can I read the USB Descriptor by C#? I found LibUSB.NET but I can't get USB devices like in examples: UsbRegDeviceList allDevices = UsbDevice.AllDevices; it returns count = 0 回答1: It appears this question was asked and answered quite a while ago now.
