Follow-ups.
I tested two alternate devices yesterday:
- A (fresh) WK5 V1.1 ADT LINK USB adapter
- A WK6 V1.0 SD adapter
Both of these appear to work. Some images:
In the case of the USB adapter, I tried it with a Logitech unifying receiver, which worked and showed up successfully in lsusb.
With the SD adapter, I was able to see and mount a 128Gb microSD card (listed as /dev/sda1).
NB you should not hot swap either the M.2 device, or the card/USB device inserted into the device, while the Pocket Reform is powered on. Unhappy times will result.
I have one other wireless card to test, and I’m waiting on an antenna for my modem card still.
