usbserial

I have a MR400s taximeter hardware. I want to communicate with this taximeter using RS232 cable and I have already achieved this connection and communication in windows. But I wanted to make connection using android device. How can I achieve this? Thanks Ishan jain I use the USB to serial library, you can find it here: USB Serial for Android. It doesn't require any root access. You'll need to check if your Android device supports USB host mode. Then, using a usb OTG cable and a USB to serial adapter cable you can start communicating with your serial device via RS232. There are code examples to

I am working on this Android application that needs to communicate over USB. I have an Archos 101 Tablet (specifications here: http://www.archos.com/products/ta/archos_101it/specs.html?country=us&lang=en ). It has a full USB host port. I can put a flash USB drive in the USB port and copy files to and from the flash drive onto internal storage. I have this Arduino Fio board, with an XBee attached to it. I have an XBee Explorer Dongle with another XBee that I plan to hook into the Archos 101 tablet into the USB port. As of right now, I can put the XBee Explorer Dongle into my computer and send

Is it possible to identify a USB device by a unique identifier like an Operating system has Mac-ID, Harddisk ID, Ethernet card ID has unique identifiers? I know one can easily change the volume serial number of USB partition or it could be changed when user Formats it. But is there an ID some kind of 'USB Harddisk ID or USB Hardware ID' which could be retrieved via MFC's (Visual C++ or C#) using the WMI Service? Will such an identifier be unique to the physical device? Kindly clarify... The closest equivalent of a "unique number" available in any USB device is the VID and PID, the vendor and

I have two different USB devices based on the same USB-RS232 chips. When I plug those in the USB they are mounted to /dev/ttyUSB0...3 My problem is how, inside a script, I can find out which one is on what tty? Using lsusb I can differentiate them: $> lsusb | grep 0403:f850 Bus 004 Device 002: ID 0403:f850 Future Technology Devices International, Ltd $> lsusb | grep 0403:6001 Bus 004 Device 003: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC And using dmesg I can tell where they were mounted: $> dmesg | grep 'FTDI USB Serial Device converter now attached'

I have a rf-reader with ftdio usb to serial chip. I was able to write a program to control it using ftdi d2xx library. So far so good. The issue is that when the reader is reconnected to the PC I have to remove ftdi_sio and usbserial mods using this command: sudo rmmod ftdi_sio sudo rmmod usbserial I can't use ftdi d2xx library to connect to the reader if I don't run the code. I want to be able to add a udev rule so whenever the reader is connected kernel unload the ftdi_sio and usbserial (or not load them in first place) I've added a new udev rul to /etc/udev/rules.d with name 99-ftdi-sio

I am using an Arduino Duemilanove and Nexus 7 . I have successfully detected the Arduino board and displayed the vendor id and product id. I am trying to transfer data from my tablet to the Arduino board and trying to blink the LED on the board. The code for Android is as follows. Main Activity.java protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE); UsbDeviceConnection connection; HashMap<String, UsbDevice> deviceList = manager.getDeviceList();
