Invalid idevice_connection struct? Unable to attach <UDID> inspector

[anshumanchatterji]

Hi Team,

I am seeing this error as soon as i connect my iPad.

Invalid idevice_connection struct?: Undefined error: 0 Unable to get connection file descriptor.: Undefined error: 0 ss.remove_server_fd(5) Unable to attach c70fbb163gd3edee9bf781e0052d24a1111bb56e inspector

What I did:

brew install ios_webkit_debug_proxy
brew update
brew doctor


Then i corrected all the warnings as suggested by brew doctor. And ran this command:

ios_webkit_debug_proxy -d

the output was:

ss.add_server_fd(3)
ss.add_fd(4)
ss.add_server_fd(5)
ss.remove_server_fd(5)
ss.recv fd=4 len=978
ss.add_server_fd(5)


but as soon as i plugged in my iPad, i got this error:

Invalid idevice_connection struct?: Undefined error: 0
Unable to get connection file descriptor.: Undefined error: 0
ss.remove_server_fd(5)
Unable to attach c70fbb163gd3edee9bf781e0052d24a1111bb56e inspector

What fixed the problem for me:

The working MacMini had libimobiledevice v1.1.5, and the two non-working MacBooks had v1.1.6.

So I had to downgrade the libimobiledevice to v1.1.5

Steps:

Type this on Terminal

1. cd /usr/local
2. git checkout 7e209f0 Library/Formula/libimobiledevice.rb
3. brew unlink libimobiledevice
4. brew install libimobiledevice

Hitting same issue. Steps above work perfectly.

If your brew git is not initialized, run brew update between steps 1 and 2.

Thanks! Your fix solved this error for me.

seems to be fixed after upgrading libimobiledevice to 1.1.6
