Hi,
I'm trying to communicate to my custom HID device. I initiated a
connection from my laptop to my device, and I see the following in the
debug log:
Can't get HIDP connection info
I traced this to profiles/input/device.c Line 798, to function
ioctl_is_connected
if (ioctl(ctl, HIDPGETCONNINFO, &ci) < 0) {
error("Can't get HIDP connection info");
close(ctl);
return false;
}
Can somebody please tell me what this failure means? Obviously my
there is something wrong with my device (its getting an L2CAP
configuration error, looks like my laptop is asking for an MTU close
to 8k bytes). So I want to know where things are going wrong. I
suspect my HID descriptors/SDP records are messed up, but I would like
to know what part of it is wrong.
I could not find any information relating to this ioctl either. man
ioctl_list doent seem to contain a number 211 (HIDPGETCONNINFO).
Please give some suggestions on how to debug this problem.
