Hi! I'm suffering from a regression while using the usb gadget port on the sama5d3 to get terminal access to the device in question (CONFIG_USB_G_SERIAL).
I get this message when I try to connect: udc: ep: Invalid setup request: 02.01 v0000 i0081 l0, halting endpoint... A bisect blames commit v4.7-rc1-21-gc32b5bcfa3c4 "ARM: dts: at91: Fix USB endpoint nodes". And indeed, reverting that commit on top of v4.9-rc1 fixes things, although that doesn't look like the best of fixes... BTW, the bisect was extremely painful since v4.7-rc1 seemed broken somewhere in the overlayfs area. I hope I will never ever need to bisect in the v4.6..v4.7 area again. This was the second time, the first time I was chasing a gpio interrupt bug, but I never found out what was wrong and stopped looking when v4.9-rc1 turned out to be ok even though v4.8 was bad, it was just too painful to look for things that already seemed fixed. Cheers, Peter
