Dangerous Prototypes Open Source Hardware

#include <stdio.h>
#include <fcntl.h>
#include <errno.h>
#include <sys/ioctl.h>
#include <linux/usbdevice_fs.h>
void main(int argc, char **argv)
{
const char *filename;
int fd;
if (argc != 2) return;
filename = argv[1];
fd = open(filename, O_WRONLY);
ioctl(fd, USBDEVFS_RESET, 0);
close(fd);
return;
}

The usage is usbreset /dev/bus/usb/XXX/YYY where XXX is the bus number (nearly always 001 on the Pi) and YYY is the device number (get both of these from lsusb)."

#!/usr/bin/env ruby
usbs = `find /dev/bus/`
usbs.each_line { |usb|
        next unless usb.include?("/001/") # Try to disable this line if it does not find it
        ls = `lsusb -D #{usb}`
        next unless ls.include?("04d8:fd08")
        `./reset-usb #{usb}`
}

So is there any reliable way to use this in LINUX ?

$ echo '$' > /dev/ttyACM0
$ ./fw_update  -e -w -v -m all -vid 0x04D8 -pid 0xFD0B

Wow, nobody is here. Anyways, the problem seems that the device goes into debug mode after some time of inactivity (or some other reason) and needs a replug to get working again.
