We have a Java/Spring application that’s trying to access the 'ttyUSBx" ports on the current build of Linux linaro-alip 4.2.4-linaro-lt-qcom (46) on the Dragonboard 410c. One of the devices we’re trying to connect to is the “Digi XStick Adapter” using either of the “USB 2.0 (host mode only)” ports on the Dragonboard 410c. We can see the USBx devices in ‘dmesg’ as well as ‘lsusb -v’ at the OS level (Below), but are getting the following error when trying to access the USBx ports via the Java Driver:
