Ok, let me try. I undid all the changes in drivers/phy drivers/usb and include/linux/usb . I have all the gadget stuff built-in, so that I could use nfsroot, but this is boot from mmcblk. gzipped config is attached. PC is unable to work with the gadget: [256526.716099] usb 2-1: new full-speed USB device number 52 using uhci_hcd [256526.832091] usb 2-1: device descriptor read/64, error -32 [256527.052095] usb 2-1: device descriptor read/64, error -32 [256527.268160] usb 2-1: new full-speed USB device number 53 using uhci_hcd [256527.388121] usb 2-1: device descriptor read/64, error -32 [256527.608116] usb 2-1: device descriptor read/64, error -32 [256527.824170] usb 2-1: new full-speed USB device number 54 using uhci_hcd [256527.851175] usb 2-1: device descriptor read/8, error -32 [256527.975175] usb 2-1: device descriptor read/8, error -32 [256528.188133] usb 2-1: new full-speed USB device number 55 using uhci_hcd [256528.218184] usb 2-1: device descriptor read/8, error -32 [256528.343183] usb 2-1: device descriptor read/8, error -32 [256528.444314] usb usb2-port1: unable to enumerate USB device Dmesg from the n900 is attached as /tmp/delme.gz. I did _not_ apply the patch from https://lkml.org/lkml/2016/3/24/670 , yet, as I'm using devicetree boot.
