I've been looking through /usr/include/usb.h to try to simplify some of my code.
Currently I find a device by looping through usb_get_busses() This returns a struct usb_device >From this I extract the UsbDev->bus->dirname, UsbDev->filename to build a device path "/proc/bus/usb/dir/file" so I can fd = open(device_path, O_RDWR); >From this I can issue ioctl(fd, ...) calls to upload my firmware But then I use libusb again with UsbHandle=usb_open(UsbDev) and keep on working with the UsbHandle to pass on my bulk data. My question is: can I simplify the firmware upload - getting directly fd from the UsbHandle ? - replacing the ioctl calls by calls to libusb ? This is probably an easy question, but I'm still a bit confused by the separate APIs used to do similar things.
