I'm having trouble connecting to a GPS module with my Edison.
I'd like to read from it (obviously). But I cannot find which device it is. After more searching than I'm happy about, it seems that I should be looking for /dev/ttyUSB0. However, I have yet to see that device.
I already tried switching to the unofficial opkg repo and installing the FTDI driver from there. I ran into the issue of the default partition being too small. So then I resized my partition size as per this post (to be clear, I completed step 4 and stopped) and ran "opkg install kernel-module-ftdi-sio". There was no complaint trying to install it after resizing the partition. But that still didn't solve the issue, and /dev/ttyUSB0 is still nowhere to be found.
I'm trying to avoid having to install a new image/kernel if I don't have to. I want to verify that this isn't a problem on my end before I do that.
Let me give some more background on the problem.
-I am using the Spark Fun Edison base block (among other blocks).
-There is an OTG cable connected to the "OTG" port on the Edison
-From there I connect to one of these USB-Serial adapters
-I made a connector to connect the adapter to this GPS module, as well as to power the GPS (from an external 3.3v source). One of the 2 ground pins on the GPS is wired to the ground of the 3.3v power supply, and the other ground pin is connected to the "VSS" pin on my USB adapter. GPS Tx to adapter Rx and GPS Rx to adapter Tx.
-I'm connecting to the Edison from a Win8 machine via putty and serial over USB to the "Serial" port, and sometimes putty via SSH over WiFi (Edison is in/out of AP mode as needed)
-I'm running "Poky (Yocto Project Reference Distro) 1.7.2", according to the message at the end of the boot sequence
-lsusb returns an FTDI device every other boot (I've seen elsewhere on here that the USB-only-on-every-other-boot bug is a thing -I'm not trying to tackle that at this moment, maybe later)
-lsusb "good" output:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
-I see /dev/bus appear whenever lsusb would also tell me there's an FTDI device. However, I kinda get the sense that's not exactly what I'm looking for here, so I didn't spend too much time with it. (but maybe I'm wrong?)
So, how do I connect/read this GPS device? Am I missing something here? I would appreicate any assistance.
