I would like to write an application that will create an 'image' of a flash drive. This includes the total topography of the drive, not just the files. So if the drive is 4GB you get a 4GB file. Is this possible, and if so, could someone point me in the direction of information on how this may be accomplished? ...
I've got an Atmel AVR A90USBxxxx device that I have configured to "talk USB" via CDC. It's designed to take input from a Host computer, running Windows, Linux, or OS X. I'm under the impression that Linux and OS X will immediately recognize this CDC device, and with a simple .inf a Windows machine can be told my VID/PID should be opene...

I have been toying around with PyUSB lately, and found that it works beautifully on Linux (Ubuntu has libusb 0.1 and 1.0, as well as OpenUSB)... but only if I run the program with root privileges (with sudo, of course). Can anyone tell me why it requires elevated privileges and, more importantly, if I can change the permissions somehow ...
I am writing code for a USB device. Suppose the USB host starts a control read transfer to read some data from the device, and the amount of data requested (wLength in the Setup Packet) is a multiple of the Endpoint 0 max packet size. Then after the host has received all the data (in the form of several IN transactions with maximum-siz...
What browser-based technology would allow me to query the client's currently connected USB devices - specifically name and device id of these. Of course, I'm ok with the client having to allow and confirm such an activity. I don't care if at low-level, it uses WMI, direct access or some other sort of access layer, all I want is to be a...
Is there a list somewhere of all iProduct USB prodcut ids? I use the IOKit to get notifications for attached/detached USB devices and would like to identify the device. Currently i get the device name and search for "iPod" and "iPhone" but i guess that's not really safe since it could also be an accessory (or could it?). Regards, Erik ...
