I wish to share a USB device between two NSLU2's. They're at a remote site and the idea is that if the NSLU2 connected to the USB device crashes/dies, the other will take over the device and continue operations. That would save me from a 300 km drive if the main NSLU2 crashes hard.
So I got a KVM switch which does what I wish. It can be connected to two computers and it's possible to grab control of the USB device by hitting scroll lock twice. So I wrote a program to hit scroll lock twice for me, which I can run from command line: #include <fcntl.h> #include <stdio.h> #include <linux/input.h> int main(int argc, char** argv) { int i, fd; struct input_event event; fd = open("/dev/input/by-id/usb-Tangtop_USB2.0_DATA_SWITCH_9008151-event-kbd", O_RDWR); if (!fd) return 2; event.type = EV_KEY; event.code = KEY_SCROLLLOCK; for (i = 3; i >= 0; i--) { event.value = i & 1; write(fd, &event, sizeof(event)); usleep(100000); } return 0; } This works on my x86 PC, but not on my NSLU2 running lenny. The switch is recognised and /dev/input is populated correctly, it seems. Does anyone know why it still doesn't work? Is what I'm trying at all possible? -- Steinar ; NIL DIFFICILE VOLENTI ; http://latinitas.org ; http://voksenlia.net -- To UNSUBSCRIBE, email to debian-arm-requ...@lists.debian.org with a subject of "unsubscribe".
