Re: wlan0 EXPIRED RA with B+ with 3-13-18 raspian

The update did not seem to matter. I hate to view this as a solution, but my shell script that disconnects and reconnects WiFi every hour seems to resolve the problem. A work-around like this is not very satisfying but I may just go ahead and deploy my PI B+ with this fix. I'm not going to have muc...

No. There is no RW storage on the Pi HW (apart from a very few bits of OTP memory which cannot be used in a 'bad' way), everything is on the SD card.

Re: can I remove the USB Hub chip on the Pi3B+ to Gain Gadget Mode

Removing the hub == removing ethernet and USB completely. In any case, no, what you seek is impossible. It doesn't matter what you remove, only the Pi0 series (and I think the PiA+) can be used in gadget (USB Slave) mode. That's because they don;t have the hub in the way. remove the hub, and it *mi...

Might be worth doing a update/upgrade cycle. The repo was updated today with various bug fixes from upstream and internally. Otherwise at a bit of a loss what to suggest. It cannot be common since this is the only report.
