Just getting the TX2 one week ago and I’m trying to setting up some sensors for a project. I’m particularly interested to plug an IMU (xsens mti) on the micro usb A port using the micro usb / usb adapter provided with the Jetson.
However, when I plugged the IMU into the adapter I’m not able to see a /dev/ttyUSBX . So here are my questions :
1- Is it a reasonable idea to plug such a device through the micro usb / usb adapter ?
2- What should I do in order to make appear a /dev/ttyUSBX needed by the xsens driver ?
My revision of the Jetson :
nvidia@tegra-ubuntu:~$ head -n 1 /etc/nv_tegra_release # R27 (release), REVISION: 1.0, GCID: 8566447, BOARD: t186ref, EABI: aarch64, DATE: Thu Mar 2 05:14:54 UTC 2017
My ubuntu is able to see the device (result of dmesg cmd) :
[ 5844.256158] tegra-xudc-new 3550000.xudc: device mode on [ 5844.261422] tegra-xudc-new 3550000.xudc: device mode off [ 5844.266919] tegra-usb-cd usb_cd: notification status (0x1, 0x0) [ 5844.272916] tegra-usb-cd usb_cd: disconnected USB cable/charger [ 5844.278884] tegra-usb-cd usb_cd: set current 0ma [ 5844.283537] tegra-xudc-new 3550000.xudc: entering ELPG [ 5844.289910] tegra-xudc-new 3550000.xudc: entering ELPG done [ 5845.676700] extcon-gpio-states external-connection:extcon@1: Cable state 2 [ 5845.792755] extcon-gpio-states external-connection:extcon@1: Cable state 2 [ 5847.100448] usb 1-1: new full-speed USB device number 21 using xhci-tegra [ 5847.234238] usb 1-1: New USB device found, idVendor=2639, idProduct=0003 [ 5847.241004] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 5847.248240] usb 1-1: Product: MTi-30 AHRS [ 5847.252311] usb 1-1: Manufacturer: Xsens [ 5847.256271] usb 1-1: SerialNumber: 036006B6 [ 5847.261481] xhci-tegra 3530000.xhci: tegra_xhci_mbox_work mailbox command 6
Thanks for your help !
Note: My other USB (3.0) is already in use by a high frame rate camera on the system.
