Hello,
We used Jetson Nano EVB (B01 version) to verify our AI functions.
System sometimes can’t detect USB hub when cold boot, need to reboot or to power on/off system again.
We check usb hub status as below, we found usb hub (RTS5411) not detect at USB 2.0 bus
lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 5000M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 1: Dev 3, If 0, Class=Mass Storage, Driver=uas, 5000M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/5p, 480M
dmesg (these messages sometimes happened, but sometimes no errors)
usb 1-2: new high-speed USB device number 5 using tegra-xusb
usb 1-2: device descriptor read/64, error -71
Is there anyone can help? Thanks!
