Title:
  qemu-system-arm black screen and keyboard not detected

Status in QEMU:
  Incomplete

Bug description:
  Hi guys,

  I try to emulate FreeRTOS with this guide : 
http://wiki.csie.ncku.edu.tw/embedded/Lab32
  But, the keys on my keyboard are not taken into account. 
   - Command line : qemu_stm32/arm-softmmu/qemu-system-arm -M stm32-p103 
-monitor stdio -kernel build/main.bin -semihosting
  If I try to add usb flag with : qemu_stm32/arm-softmmu/qemu-system-arm -M 
stm32-p103 -monitor stdio -kernel build/main.bin -usb -device 
usb-host,hostbus=1,hostaddr=1 -show-curso
  I obtain this message "qemu-system-arm: -device 
usb-host,hostbus=1,hostaddr=1: 'usb-host' is not a valid device model name"

  My second option is try with the latest version of qemu with this
  command line : "qemu-system-arm -M lm3s6965evb -monitor stdio -kernel
  build/main.bin -semihosting" but I obtain a black screen.

  Could someone guide me on this problem ?
