A Pi2 running armv7 releng/14 reports sysctl: unknown oid 'hw.usb.ucom.debug' at line 10 when booting. The intent was to understand why it drops ssh connections when they are used to communicate with an ftdi usb-serial adapter. A few other hosts running -current accept the debug setting and generate copious output in response. Man pages suggest the option is available on stable, -current and releng/, but it seems to actually work only on -current, at least for armv7. Thanks for reading, and any hints what might be done wrong. bob prohaska
