How do you mount usb devices? Trying to pass through iphone

[ilyas121]

I cant seem to allows usb access through permissions on snap? I've tried alllowing apparmor and creating a new rules.d, but I get Operation not permitted for accessing usb every time.

Update, I've been able to connect sosumi:raw_usb to :raw_usb , but I still can't get iphone to connect.
I also updated the usb line in the launch file to have:
-usb -device usb-kbd -device usb-mouse -device usb-host,hostbus=1,hostport=5
The behavior when trying to connect my iphone is that it will connect and then disconnect, while incrementing the device number.

I wonder if it retries after each disconnect for 3 times but needs to retry more ofter? Really don't understand how qemu works.

I think its similar to the issue described here: https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04585.html

So it looks like this change was added to the official qemu repository: https://patchew.org/QEMU/[email protected]/
However, it seems that the qemu that is installed is out of date?

Any news? Did you get it working?

[ilyas121]

Can't work because of QEMU version. I forge the exact version that the dev team solved it but this repo uses too old of a version.

For anyone else looking at this, I had the same issue and was able to fix it by just switching from Sosumi to the non snap version here: foxlet/macOS-Simple-KVM. It's functionally the same, and I believe this is just that repo but packaged for Snap. Since it doesn't bundle an old version of QEMU usb passthrough works out of the box
