Device is XB3-C-V1-UT-001
Firmware is 1516
Host OS is Ubuntu 18.04
When I enable USB direct via XCTU I can see that the device switches to USB because dmesg shows an attempt at enumeration, however the device never successfully enumerates.
Instead of adding a connector for testing, I have a USB cable soldered directly to the pin of 7/D+ 8/D- and GND.
dmesg output shows:
usb 1-4: new low-speed USB device number 11 using xhci_hcd
usb 1-4: device descriptor read/64, error -71
it tries multiple device numbers
usb usb1-port4: unable to enumerate USB device
Do I need to update the Telit modem directly to use USB direct?
