From 821ca608d81640f1ed10fc5540eb8df18dfa6679 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Fri, 5 Nov 2021 12:52:55 -0400 Subject: usb: Use the first available device for ehci_gadget For whatever reason, usb_setup_ehci_gadget removes and probes USB device 0. However, not all systems have a device 0. Use the first device instead. The device probed should probably have something to do with the controller (as specified by e.g. ums or fastboot ). In fact, I find it odd that we probe the USB device in the first place, because this is just to set up the gadget itself. Presumably, the controller should be probed by usb_gadget_initialize somehow.
