I have loaded the Sample box image on a pi2 and all seems to boot ok but when the keyboard is connected, the console give the following:
usb 1-1,2: new full speed usb device number 5 using dwc_otg
usb 1-1,2: device descriptor read/all, error -110
usb 1-1-port2:unable to enumerate USB device
and doesn't work. Keyboard is usb connected Carillon I control 61. More lately called Miditech I2 Control. Any help welcome please. Also does image support wifi network?
