Accesories bug
When i plug my iPhone 8 into the pi it says the accesories dosen't work with it i dont know why
Could you give us the exact error message, maybe with a screenshot (in English). Was the iPhone locked or unlocked at that time? If locked, can you try unlocked in case USB restricted mode was active? Remember that you need to pair your iPhone with the Raspberry Pi, and that will require your passcode.
My iPhone was unlocked and my iPhone says that

What iOS version are you running, and what version of libimobiledevice? I never saw that message here, but maybe there's an incompatibility? (for reference, I'm running iOS 13.3.1 with libimobiledevice 1.2.1~git20181030.92c5462-2 from Raspbian)
i run the IOS 13.3.1 (17D50) and i dont know the way to know the libimobiledevice version but i install it the last week sorry for my english im french :0
If you installed following the instructions in the README and have ssh access to the box, try running dpkg -l |grep libimobiledevice. You can reply in French but please add the English version as well for other people reading by.
Ok thanks i have the same version that you im with VNC viewer so i can send screenshot of drive "PIBACKUP" if you need
Then I don't know. It might help to check if the device is detected by running ideviceinfo on the box. Also check the logs from journalctl when you're connecting the device. Did the device ask your passcode to pair pibackup at one point or never?

Ok so it's correctly detected. What happens if you manually run the idevicebackup2 command?
It give that error the idevice show up the syncro logo and its stop after 30 seconds, the software says PIBACKUP dosent exist i dont know why

For information PIBACKUP is on a USB HDD
It's likely not mounted. The segmentation fault looks bad though. I'd say it's an upstream issue from libimobiledevice so please report that directly there: https://github.com/libimobiledevice/libimobiledevice/issues
