Today I tested: Some new toys
With the Ever Given having been dislodged, my toys arrived.
One thing I tested is a USB 3.0 to gigabit ethernet adapter. Mine has a USB-A male connector, so I can use it with any random computer, or in a dock connected to the Librem 5, or via a USB-A female to USB-C male adapter direct to the Librem 5.
Both ways of connecting to the Librem 5 worked out-of-the-box. Tick.
Another thing I tested is a USB-C external SSD drive, for connection direct to the Librem 5. That worked out-of-the-box, other than that the drive arrived formatted as
exfat and the Librem 5 doesn’t have support for that type of file system out-of-the-box. Reformatting the drive as
ext4 fixed that. Tick.
While this can’t be used to make a reliable backup of the eMMC drive, it can be used to back up stuff on the uSD card and can be used for casual backup of user files on the eMMC drive, and can be used for sneakernet (moving files on or off the Librem 5).
The third toy that I tested was a dock. That should allow charging of the Librem 5 (USB-C power passthrough) while connected to the above devices and (not tested) connection to an HDMI monitor. While charging worked, and the above devices worked, after a while the red light began to flash, charging stopped and the Librem 5 appeared to overheat. So I powered off and gave it a little rest. Needs more testing.
