Getting USB to work

[mlozier]

This script is awesome!! I'm having difficulty getting USB to work. I want to connect an iPhone to my host laptop and have it show in the MacOS guest. Also, my laptop's webcam is connected to the USB bus -- I would like for it to show so that FaceTime can be used. Do you have any information on this?

Thanks so much!

Connecting the iPhone is near the top of the list.

Yes I believe you can passthrough a USB webcam quite easily.

I have only attempted the iPhone passthrough, a few months ago.

See for generic passthrough https://github.com/sickcodes/Docker-OSX#allow-usb-passthrough

Alternatively, it would be possibly to connect using Linux + checkra1n's usbmuxd hax and then passthrough the iPhone that way. I'll work on it after I finish up what I'm currently doing but here is what might work https://github.com/libimobiledevice/usbmuxd

Working guide here by Reddit user "stochad"

On my laptop everything runs on the same IOMMU group for whatever strange reason... So I either cannot use any USB's and just the iPhone or passthrough. Working on this, however.

Snipped from: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Setting_up_IOMMU

#!/bin/bash
shopt -s nullglob
for g in `find /sys/kernel/iommu_groups/* -maxdepth 0 -type d | sort -V`; do
    echo "IOMMU Group ${g##*/}:"
    for d in $g/devices/*; do
        echo -e "\t$(lspci -nns ${d##*/})"
    done;
done;

Whichever group the iPhone is within, everything within that IOMMU group must be passed in together.

iPhone passthrough has been solved here: https://github.com/sickcodes/Docker-OSX/issues/133#issuecomment-836855901

I am yet to try it but it is confirmed working.

This is still an issue due to usb resetting in non-vfio mode.

However, if the stars align and your iommu groups are separated properly, or you have linux-zen with acs override patch (extremely dangerous security-wise), you can split the groups up and pass through the iPhone in an orderly fashion.

At your own risk, see dangers: https://vfio.blogspot.com/2014/08/iommu-groups-inside-and-out.html

Arch users easy-way to test:

• Boot into linux-zen, available on the AUR (add -zen at GRUB/rEFInd).
• Add boot arguments: pcie_acs_override=downstream,multifunction

Every time I return to this my keyboard/trackpad/external drives get sucked into the VM through the phat iommu group and need to reboot.

TL;DR, Laptops BTFO, Desktops OK

Cool way would be use usbredirserver: https://github.com/sickcodes/dock-droid#passthrough-android-webcam-camera-over-the-network

Interesting article from @MacMiniVault about USB redirections: https://www.macminivault.com/sharing-a-usb-device-with-a-remote-mac/

I swear we should be able to just literally usb redir the iPhone like this lol https://github.com/sickcodes/dock-droid#passthrough-android-webcam-camera-over-the-network
