Greetings, I'm a retired software developer, somewhat new to Linux--especially internals. I'm trying to write an application in c++ to operate the new Meade Instruments Deep Sky Imager (DSI), which is a simple CCD camera designed for amateur astronomy.
Of course, Meade supplies an application that runs on Windows but I hope to create a Linux version and post it on SourceForge, as I have done with some other software I've written (http://www.sourceforge.net/projects/kuery) I'm primarily an applications guy (running SuSe 9.3/KDE/KDevelop), and I've hoped there might be a way I can perform raw USB i/o using open, read, write, close from c++ using a device /dev/usb/ttyUSBxxx. Specifically, I'm hoping I can avoid having to learn much about the details of the usb API and use some high-level stuff instead. I notice several puzzling things: /proc/bus/usb/devices refers to buses, ports and addresses, atrs, but /dev/usb/ttyUSBxx has major and minor device numbers. Is there a correspondence of some kind? If the camera is on bus02 port02 is there a way I can determine which /dev/usb/ttyUSBxx to open and perform reads on? Can you point me to some (non low-level API) documentation on this subject? Better yet, to some sample application code?
