Hmm, looks like it should be changed, no?
SLE has CONFIG_USB_GADGET=n, so doing that would be a rather big change
which needs discussion. It's not just a module which can be marked as
unsupported. I don't know whether any platform currently supported by
SLE even has USB device controllers.
Currently SLE has CONFIG_USB_GADGET=n.
I tried to enable CONFIG_USB_GADGET some time ago. IIRC There were some
concerns that we had nothing to test it on intel boards (some support it,
but it's rare). On top of that there are security implications to take
Correct. And the security implications make me very nervous. That
direction is not tested or spoofed for security.
Can someone please outline what these security implications are?
1. Without further configurations from userspace, no endpoints/functions are
2. Contrary to e.g. Firewire and Thunderbolt, USB does not allow Remote DMA,
but FW and TB are both enabled.
