Hi all,
I've stumbled upon this Bug (
https://bugzilla.novell.com/show_bug.cgi?id=1108320) asking for USB
gadget support. The bug's resolved since adding it on Leap seems
unlikely. Yet I see it's enabled for arm64 on Tumbleweed. Would it
cause any problem for us to also enable it on x86_64?

menuconfig USB_GADGET
Enable this configuration option if you want to run Linux inside
a USB peripheral device.

Is this the case for x86_64? What device you have and is not
supported
in tumbleweed? Do you have an lsusb output?

The user that created the bug points to this library:
https://wiki.analog.com/resources/tools-software/linux-software/libiio#how_to_build_it
It seems to need gadget support to build/run some of it's components. I
can't really comment on why the library needs it.

We do provide this module in tumbleweed:
https://kernel.opensuse.org/cgit/kernel/tree/drivers/usb/roles/intel-xhci-usb-role-switch.c?h=stable
It adds USB host/device switching capabilities on some Intel platforms
and it's useless as long as we don't add gadget support. Sadly, I don't
have any HW available to test it.

Even if a corner case, someone may want to play around with it.

Best,
Nicolas


thanks,
