/dev/hidraw: read permissions

What do I need to do to have read permissions on /dev/hidraw*? I'm seeing stuff about udev rules and saw this on the net, but the world of udev is like a foreign land to me, and if there's some sort of a simpler solution where I just add myself to a group that'd be dandy... (Ubuntu 13.10 Preview) Feel free to retag the question - I'm not too keen on what 'hidraw' exactly goes under. EDIT: H'okay, so, just some more information to clarify the issue: I literally stepped through code that called the POSIX open() method, and got the errno for insufficient permissions. Running cat on the file as a normal user results in an insufficient permissions error, while running under su results in a successful (albeit meaningless) cat operation. EDIT EDIT: At request, I'm providing the relevant code with POSIX call. It's from the HIDAPI library by Signal11 (function hid_open_path). I trust that this code is correct, as it has apparently been in use for quite some time now. I've added a comment located where the relevant errno reading took place in GDB. hid_device *dev = NULL; hid_init(); dev = new_hid_device(); if (kernel_version == 0) { struct utsname name; int major, minor, release; int ret; uname(&name); ret = sscanf(name.release, "%d.%d.%d", &major, &minor, &release); if (ret == 3) { kernel_version = major device_handle = open(path, O_RDWR); // errno at this location is 13: insufficient permissions /* If we have a good handle, return it. */ if (dev->device_handle > 0) { /* Get the report descriptor */ int res, desc_size = 0; struct hidraw_report_descriptor rpt_desc; memset(&rpt_desc, 0x0, sizeof(rpt_desc)); /* Get Report Descriptor Size */ res = ioctl(dev->device_handle, HIDIOCGRDESCSIZE, &desc_size); if (res device_handle, HIDIOCGRDESC, &rpt_desc); if (res uses_numbered_reports = uses_numbered_reports(rpt_desc.value, rpt_desc.size); } return dev; } else { /* Unable to open any devices. */ free(dev); return NULL; }
