I wrote this code to subscribe to USB devices being plugged in and unplugged; the point is for IOKit to deliver notifications to my iAttached() and iDetached() functions when the corresponding events occur. However, I don't get notifications. The code can be seen here: http://gist.github.com/402391 I didn't want to over-populate this p...

Good afternoon, WinUSB is working well on the development computer that I am using (Win XP SP3). I am able to download new firmware to the Cypress FX2, and then connect to the new USB device once it 'renumerates'. However, if I've tried the same code with the WinUSB driver on a few other computers (Win XP SP3, Win7 x64) and they both ...

Not exactly a programming question, but close. I'll try my luck anyway. The keyboard wedge barcode scanner inserts the translation device between the reader and the keyboard. Data sent through a wedge appears as if it was typed into the computer, while the keyboard itself remains fully functional. Because a computer usi...
hi, i want to send/receive data from my arduino board with a python script. I would like to do it using python and its pySerial module which seems to fit my needs. So i installed python and pySerial within cygwin (windows XP behind)) the python script is rather straight forward : $ cat example.py #print "testing my COM26 port using p...
I want to develop a USB host on an embedded device that will talk to printers from various vendors. Drivers for the vendor specific printers would be available on PC which is ultimately communicating with printer but my device is facilitating this communication and needs to perform the basic handshaking/setup of the printer (i.e, it nee...
I would like to use Android phones as a way to do some processing and visualization of a sensor that would be attached to the USB port on the phone. The sensor would plug into the micro/mini USB, and then I would need to read the incoming data from the USB serial port. Is this possible? I have heard of people using Android to steer rob...
Hello, I got a RFID reader (GigaTek PCR330A-00) that is meant to be recognized under linux/windows as a (Human Interface Device) keyboard/USB. I hate to say this but it is working as a charm under Win7 but not "really" under Linux. Under Debian-like distros (x/k/Ubuntu, Debian,..), or Gentoo, or... I just can't have the device working...
I'm attempting to create a program that takes input from a usb ps2 hand controller, translate and passes the info to a rs232 device. I already have everything working for the rs232 device. The problem is interfacing with a usb controller. There doesn't seem to be any good documentation out there and on top of that .NET3.0/3.5 doesn't hav...

I'm trying to get the mount point(linux/osx) or disk drive (windows) of a specific USB mass storage device. I can use libusb to determine if the correct device is inserted but how do I determine where it is mounted? I'm using C++ but I assume C code would work just as well. Cross-platform code would be preferable. ...
I understand this can seem a bit weird. So I'll give more details. Is it possible for my computer to interact with some kind of "coin collector" ( just like the kind that's used in a vending machine ) ? Basically I'd like to be able to implement the following methods public void onCoinInserted( Coin coin ){ if( coin.value == 10 ) ...
Hi all, Is it possible to simulate a USB drive with software only? I mean, for example, to expose a local memory space to the OS so the device manager will recognize it as a USB device. I'm not familiar with hardware implementation, but I'm sure that it is possible somehow to emulate the USB protocol. I began with this book - USB Desig...
I have a machine in a remote location that contains an SD card slot as its only output. I would like to read the output without needing to physically go to the machine and remove the card. My idea is to place a PC next to the machine and connect the SD card slot of the machine to a USB or serial port or some other input on the PC. Is t...
