It shows up as an "X10 Wireless Technology Inc USB Receiver" with three devices: /dev/ugen0, and the corresponding input (/dev/ugen0.1) and output endpoints (/dev/ugen/0.2). Also see the attached usbctl output. Simply reading from the input endpoint /dev/ugen0.1 doesn't work. This page (http://remotew.free.fr/linux_en.htm) points at the Gatos project, which has a Linux driver (ati_remote) that seems to make the remote show up as a USB keyboard: http://sourceforge.net/project/showfiles.php?group_id=12629 That driver sends a couple of magic bytes to the device during initialization. I'm trying to do the same from userland: static char init1[]= { 0x80, 0x01, 0x00, 0x20, 0x14 }; static char init2[]= { 0x80, 0x01, 0x00, 0x20, 0x14, 0x20, 0x20, 0x20 }; int main(int argc, char *argv[]) { int out = open("/dev/ugen0.2", O_WRONLY); if (out == -1) { perror("ugen0.2"); goto done; } if (write(out, init1, sizeof init1) == -1) { perror("write init1"); goto done; } if (write(out, init2, sizeof init2) == -1) { perror("write init1"); goto done; } done: close(out); } Really simply. Here's what happens when I run it: write init1: Input/output error it feels like I'm missing something extremely obvious, but I'm new to the USB internals. The two endpoints are "interrupt" endpoints. I'm not sure what that signifies, but I heard writing to them on -stable is broken, but on -current it should work. Any ideas?
