Dell Latitude E5*50 Linux support
Tested on my Dell Latitude E5450 (late 2014) with Fedora 21 64bit
WWAN module
The Dell Latitude E5*50 could have a "Dell Wireless 5809e Gobi™ 4G LTE Mobile Broadband Card" WWAN module. It's based on the Qualcomm Gobi™.
| Name | Dell Wireless 5809e Gobi™ 4G LTE Mobile Broadband Card |
| ID | 413c:81b1 |
| Kernel module | qcserial |
The device id of this Gobi™ module is still missing from the qcserial devices table, so I created a udev rule which loads the qcserial module, switchs the bConfigurationValue from 2 to 1** and add the new device id 413c:81b1 to the qcserial driver.
** By default the device is loaded in the cdc_mbim mode (see https://www.kernel.org/doc/Documentation/networking/cdc_mbim.txt) instead in the classic serial modem mode.
GPS
To start the GPS
echo "\$GPS_START" > /dev/ttyUSB0
To stop the GPS
echo "\$GPS_STOP" > /dev/ttyUSB0
In the bin folder you can find an utility (gobigps) to easily start and stop the GPS.
