Err value: Busy

[Dadoum]

I built on Fedora Rawhide netmuxd, but I can't get it to work. Every time I plug my device, it errors and tells that the USB is busy.

Output:

I see, I’ll disable my experimental USB additions until I figure them out.

Looks like I was kinda smart when I wrote it and forgot about it, you can pass —disable-usb and that code won’t run. I’ll change it to the opposite —enable-usb until I have time to make USB actually work.

Now netmuxd does not detect anything. usbmuxd still detects when the device is plugged in, but netmuxd is not detecting it in the network. (I also have this issue with usbmuxd2)

[jkcoxson]

If I had to guess, your device isn't set up for network connections. You have to enable it through lockdown. You can write some code to do it, that's the easiest way I can think of. Lemme find an example, as I've done it before.

Still not detected by any muxer, and I saw that the code asks for setting a passcode when it fails (even if here it succeeded as the screenshot shows) so I added one, with no success.

[jkcoxson]

If you set the RUST_LOG to info does it show it’s trying to add it?

[Dadoum]

It does not seem it detects anything.

[jkcoxson]

I will look into this and see if I have the same issue with the current code base.
