Hi John,

It works now. This was my fault.

I have two AC adapters on my desk and apparently, after I made the
patch, I plugged the 14VAC instead of the 16VDC. After I removed the
patch, I plugged in the right one. The condition is reproducible if I
use the wrong adapter.

Just another reason to get rid of those AC/DC adapter and use the USB
power instead. ;-)
