Hi,

Well, IMHO is has to do with Olimex because they designed this specific circuitry, and the circuitry is such that 5V voltage constantly applied to the micro-usb connector might essentially become disconnected (at the board side) by programming -- if I understood it correctly.
The software needs to be responsible for its own actions.
Sure, ideally. That's why I reported.
Does the problem you reported occur with the Olimex image(s)? If so it may be wise to report it to Olimex.
I can't say about Olimex images at the moment because I switched to more current (alternative) images and subsequently to mainline openwrt and the board is already mounted for intended operation. Maybe I do some experiments later. I'd like to clarify, I don't blame Olimex, they are nice. Keeping close to mainline is not always easy.
If not, which commit or change caused it?
Again, I can't say at the moment. Not even sure if it could be fixed on the software side.
BTW I read in the Olimex documentation that best practice is to power it differently than the way you mention.
Yes, that is true. But powering through mini-usb is so wonderfully handy!
Thank you,
Regards, Nikolai
