Hi Peter and others, The following .config options make it possible to use USB on a Wandboard Duallite and likely other i.MX based boards. USB works for me after loading the modules manually: [root@wandboard ~]# modprobe ci13xxx_imx [root@wandboard ~]# modprobe usbmisc_imx [root@wandboard ~]# dmesg ... [ 191.791974] imx_usb 2184200.usb: pinctrl get/select failed, err=-19 [ 191.796368] ci_hdrc ci_hdrc.0: doesn't support gadget [ 191.796396] ci_hdrc ci_hdrc.0: EHCI Host Controller [ 191.796733] ci_hdrc ci_hdrc.0: new USB bus registered, assigned bus number 1 [ 191.811471] ci_hdrc ci_hdrc.0: USB 2.0 started, EHCI 1.00 [ 191.811583] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 [ 191.811599] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 191.811612] usb usb1: Product: EHCI Host Controller [ 191.811624] usb usb1: Manufacturer: Linux 3.10.0-1.0.imx.fc20.armv7hl ehci_hcd [ 191.811633] usb usb1: SerialNumber: ci_hdrc.0 [ 191.812443] hub 1-0:1.0: USB hub found [ 191.812476] hub 1-0:1.0: 1 port detected ... A test-build that includes these options and that I used for verification testing is temporarily available from koji: - http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=1975489 I have made modifications to arm-boot-config that can boot this kernel on an unmodified from upstream u-boot. A patch for a-b-c should follow in a few days. Grubby needs to be able to set the LOADADDR correctly, and I still have to look into that (/etc/sysconfig/uboot can be used until grubby knows about Wandboards).
