Thanks for the hint Alan. |

Mine looks like this: |
| 34 |
grep -r dialout /lib/udev/rules.d/ |
| 35 |
/lib/udev/rules.d/50-udev-default.rules:KERNEL=="tty[A-Z]*[0-9]|pppox[0-9]*|ircomm[0-9]*|noz[0-9]*|rfcomm[0-9]*", GROUP="dialout" |
| 36 |

I think the group "dialout" is OK. What the Virtualbox doesn't like is the ownership, the first part "root" (root:dialout) |
| 38 |
How to influence the first part. |

The strange part is that I have upgraded two system and one is shoring ttyS0 as: |
| 41 |
uucp:dialout |
| 42 |
|
| 43 |
and the another one as: |
| 44 |
root:dialout. |
