I want to use a basic Samsung phone SM- B310E as a gsm modem to initiate a call through AT commands from my pc. This phone can be connected to pc using the normal USB cable. But I don't know how can I make it work as a gsm modem.
Please tell how this can be achieved? If this is not possible then please tell any other way to achieve the same. I am using a non-Android phone.

Hello has anyone found a way to use an Arduino as a serial device and hid device at the same time?
I thought of a few solutions but didn't know the best way to go about it.
my goal is I need a serial device so the computer can send info to the Arduino but I also need an hid device.
can I use them both though 1 USB port? probably not
or
can I rig up another usb or serial port on the Arduino and use that as hid?
or
should I connect the Arduino to a teensy and use that for hid?
Thank you just trying to find the safest solution I'm making a custom fixture for my little laser engraver.
I recommend getting an Arduino Leonardo, Arduino Micro, an A-Star 32U4, or any other Arduino-compatible ATmega32U4 board. These devices act as a USB serial port but they can also be an HID at the same time if you use the Keyboard or Mouse libraries that comes with the Arduino IDE.
I am using Ableton Live 6 Lite with M-Audio Fast Track connected through USB port. I am having the following issue which I do not know how to resolve: I cannot simultaneously use sound recording with the above mentioned setup and a USB connected keyboard (just a regular USB keyboard which I use with my Toshiba Laptop PC). Either keyboard is not working or no sound reaches Ableton Live software. Any help would be really appreciated. Thanks.
It sounds like you are using a USB hub which does not have its own power source. You are drawing too much current so only one device can be powered at a time. Use USB ports directly on your computer or get a USB hub with its own power adapter.
The company I am working for has it's own ARM embedded device and currently I am starting a project with it to communicate with a dial-up modem. The modem and the device are to be connected via serial TXD and RXD ports.
My question is, how do I go about troubleshooting communications between the ARM device and the modem? For instance, before even starting with the ARM device, I connected the modem to a laptop via TTL USB connector and sent commands to the modem using Putty. I know how to use the ARM device software to send commands to the modem, however there is no screen on the ARM device so there is no way for me to know for 100% certainty if a command was sent to the modem or not. I guess what I am really asking, is there a way to use a laptop just as a "window" or "viewer" to monitor communications between the modem and the ARM device?
I'd like to connect a beagleboard-like (custom developed) omap board to a Windows PC using a virtual-com setup. That is, i'd like the board to appear to Windows as a com device and get the COM to send data to our application on the board. The main reason for that is to use virtual-com drivers on windows, since the usb drivers we use now to directly sent data over usb between the host and the board seem not to work properly.
I have done this using the FTDI driver on the past but as far as i know it worked because the device had an FTDI chip that translated the usb protocol to serial signals (am i right ?).If there's no USB to UART bridge on the board, how could i do that ?
By the way, how USB Communication Device Classes fits here ? Should develop a CDC driver for the board ? What should I use then on Windows side ?
I'm kind of confused, so any help will be greatly appreciated :)
Well, i answer myself :)
The solution lies in the Linux USB Gadget Subsystem.
Gadget API
I'm using an Arduino to read data from the web and display it. I can easily pass the data as serial using the supplied drivers, because they identify the COM port so I can send serial to the COM port.
However, I want to use 'real' USB techniques so the device can be plugged in and out like a normal USB device. I'm looking at using WinUSB as the driver. However, USB is all new to me. Is there an .inf file that uses WinUSB and an Arduino (I have an Uno)?
The lack of information on this is making me think I am going about this incorrectly.
Turns out that an Arduino Uno is not a genuine USB device.
It acts as a Serial to USB adapter. Consequently USB drivers don't talk to it.
I got round this by writing a sketch which reported back what device it was when it got the correct query from the PC.
On the PC I just iterated the Serial ports and sent the query to each port. The one that replied was the Arduino.
After that I record the port number and send serial data to the Arduino.
To learn the USB portion, maybe you could combine V-USB and the UNO?
Check out V-USB.
V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR® microcontrollers, making it possible to build USB hardware with almost any AVR® microcontroller, not requiring any additional chip.
While not necessarily Arduino, it may provide you the learning exprience you want, and let you use incorporate your UNO device.
