5 Interfaces
5.2
USB 3.0
The VisionBox provides two USB 3.0 type A ports. The supported maximum speed is 5 Gb/s. Based
on the USB specification, each port can deliver 900 mA.
5.3
Micro USB Service Port
The micro USB service port only supports device mode operation. There are two use cases:
• If a PC is connected to the micro USB port during power on, the VisionBox enters USB re-
covery mode. This is indicated by a green blinking ON LED. Only use this mode if advised
by IMAGO. Do not try to flash the Jetson OS image provided by NVIDIA!
• If a PC is connected after the VisionBox has already booted, the following USB device func-
tions are supported by the Linux OS:
o Ethernet: Provides SSH access, used by NVIDIA SDK manager for installation of SDK
components.
o UART/Serial interface
o USB Mass Storage device
Important note:
The micro USB signals are shared with the first USB 3.0 port. The USB signals are internally
switched to the micro USB port if a host is connected and providing the 5V USB supply voltage.
Therefore, any devices connected to the USB 3.0 port 0 should be removed before plugging or
unplugging the micro USB host cable during runtime. Otherwise, the integrated USB host control-
ler may fail to operate.
