I have a BQ Aquarius E4.5 and would like to connect it to various peripherals so I can use it for remote monitoring/telemetry. This would be easy to do if I could get a USB serial adapter to work.
I have an on-the-go USB cable and can plug in a USB memory stick and it will work as expected. So far so good.
I have tried plugging in a standard Aten USB/Serial adapter and I see a usbdev1.x device appearing in /dev/, but no /dev/serial and /dev/ttyUSB0 as I get when I plug it into a regular Debian machine.
Likewise, plugging in an Arduino Nano (which uses a Future Devices USB UART) works as far as: The Nano gets power and a /dev/usbdev1.x device appears – but no /dev/serial and no /dev/ttyUSB0.
No messages appear in /var/log/syslog other than "a USB device was connected".
What am I missing ? Is it "just" the USB serial module ? And then – how to install it ?
The phone is running Ubuntu Touch 15.04 (r23).
