The reason is the following bug. |
| 19 |
To use an old printer (no USB connector) I've purchased |
| 20 |
a USB-to-parallel adapater (since some software like VirtualBox |
| 21 |
cannot handle the parallel port). |
| 22 |
|
| 23 |
[my bug report 291596] : |
| 24 |
|
| 25 |
When I use 'add printer' from the cups web interface this "printer" isn't |
| 26 |
shown and I get the following entry in /var/log/messages: |
| 27 |
Nov 2 16:19:41 numa-be kernel: usb[9750]: segfault at 7fff14c30000 ip |

00007f8d3a50dc0b sp 00007fff14c2ced8 error 4 in |
| 29 |
libc-2.10.1.so[7f8d3a490000+14d000] |
| 30 |
|
| 31 |
I have started cupsd in foreground but it doesn't show any errors. |
| 32 |
Where does this error come from? |

Did this work on: |
| 38 |
- a previous kernel? |
| 39 |
- the libusb-0* series? |
| 40 |
- ever (what changed since then)? |
| 41 |
|
| 42 |
Therefore I'd like to test with the older libusb. |

Many thanks for your help, |
