Hi NVIDIA team,
We are experiencing a USB initialization delay issue on our custom Jetson Orin carrier board. Kindly help us analyze the root cause.
Hardware Information:
- Custom-designed Jetson Orin carrier board (not the NVIDIA reference design)
- J64: USB 3.0 Type-B physical connector, used for device flashing. We use a standard USB 3.0 cable for flashing
- J19 / J29: USB 3.0 Host Ports, used to connect USB hubs, keyboard, and mouse
Problem Description:
Scenario 1:
-
USB keyboard and mouse (standard USB 2.0 devices) are connected to J19 / J29 or via a USB hub
-
At the same time, J64 port is physically connected to a PC using a USB 3.0 cable
-
System is in normal boot state (not in recovery or flashing mode)
-
Keyboard and mouse take 17 to 34 seconds to become usable
-
Repeated dmesg error messages:
usb usb2-port2: Cannot enable. Maybe the USB cable is bad?
usb usb2-port2: config error
Scenario 2:
- Keyboard and mouse connected to J19 / J29 or USB hub
- J64 port is not connected
- Devices work immediately without delay
Request for Support:
- Is this a known issue related to the Orin platform or custom board design?
- Any official recommendations for hardware isolation to avoid USB 3.0 bus interference?
- Are there software-level workarounds to reduce or eliminate this delay?
Thank you for your support!
