问题 Is there a way to get an image from a usb scanner (on Windows primarily, cross-platform solution would be best) and post the image together to a form in browser with Flex or Java applet? thx! 回答1: The standardized TWAIN scanning interface is definitely the place for you to look at, rather than low-level USB, except if you are targeting only one specific device and know how to talk to it.

问题 I currently have some code that sets up notifications of connected USB HID devices within a Windows Service (written in C++). The code is as follows: GUID hidGuid; HidD_GetHidGuid(&hidGuid); DEV_BROADCAST_DEVICEINTERFACE NotificationFilter; ZeroMemory(&NotificationFilter, sizeof(NotificationFilter)); NotificationFilter.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE); NotificationFilter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE; NotificationFilter.dbcc_classguid = hidGuid; HDEVNOTIFY

问题 As some other people already asked here some years ago, I want to be able to detect in a Qt application when a pendrive/datatraveler is plugged and when it is unplugged in my system (both in Linux Ubuntu and Embedded Linux). I searched in SO and I noticed that most answers not only were very outdated (from 2010 for example), but all solutions somehow involved "non-Qt solutions" to these problem: either platform specific or usage of external libraries such as udev and DBus. What I want to know

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year .

问题 I've been assigned to display weight from weighing scale (CAS CI-201A) into a textbox using C#. The weight will be sent via serial port RS-232 or USB converter. The scale is with me but I don't know where to start. How can I achieve my goal? 回答1: Have you tried anything yet? If you want to use the serial port it makes sense to first give the user a way to select which port to use. This can be done easily, by filling a combobox with all available ports. private void Form1_Load(object sender,

问题 Is there a Bash script and/or daemon that I can write that will detect a specific USB drive and then sync that drive with a directory? 回答1: For future reference, here's how to run a bash script upon detection of a USB drive. Connect your device and run lsusb to retrieve the device's info. You should see something similar to this: $ lsusb Bus 002 Device 039: ID 0bc2:2100 Seagate RSS LLC In this case, the vendor ID of the device is 0bc2 and the product ID is 2100. Now you can create your UDEV

问题 Using pydev with python-2.7 , I wish obtain the device path of connected devices. Now I use this code: from pyudev.glib import GUDevMonitorObserver as MonitorObserver def device_event(observer, action, device): print 'event {0} on device {1}'.format(action, device) but device return a string like this: (u'/sys/devices/pci0000:00/pci0000:00:01.0/0000.000/usb1/1-2') How can I obtain a path like /dev/ttyUSB1 ? 回答1: Device(u'/sys/devices/pci0000:00/pci0000:00:01.0/0000.000/usb1/1-2') is a USB
