I built my own rootfs by LTIB using profile 'FSL gnome release package', and started linux on i.MX6Q-SABRESD successfully. But when I pluged a usb hub to OTG port and pluged a usb mouse and a usb keyboard to the hub, the mouse worked well but the keyboard can not.
When I pluged the keyboard,I got some messages as below:
usb 1-1: new low speed USB device number 2 using fsl-ehci
usb 1-1: device v046d pc31c is not supported
input: Logitech USB Keyboard as /devices/platform/fsl-ehci.0/usb1/1-1/1-1:1.0/in

SB Keyboard] on usb-fsl-ehci.0-1/input1
Besides,I found that when I pressed <ALTF1> the screen became black and <ALTF2> returned to gnome desktop.The NumLOCK and CapsLock indicator lights worked well,but I can't use other function such as typing words in xterm.
Any suggestions? Thanks in advance!
