Bug 434440 – net-print/cups-1.6.1 should pull in virtual/libusb:1 with USE=usb instead of libusb:0

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Hans 2012-09-09 12:44:48 UTC]

According to the changelog, beginning with version 1.5.3, cups requires libusb:1 instead of the old libusb:0.

From CHANGES-1.5.txt:

CHANGES IN CUPS V1.5.3
[...]
        - The USB backend now uses and requires LIBUSB 1.0 or later (STR #3477)
[...]

I can confirm this for cups 1.6.1:

$ readelf -d /usr/libexec/cups/backend/usb

Dynamic section at offset 0x7b48 contains 26 entries:
  Tag        Type                         Name/Value
 0x0000000000000001 (NEEDED)             Shared library: [libusb-1.0.so.0]
 0x0000000000000001 (NEEDED)             Shared library: [libcups.so.2]
 0x0000000000000001 (NEEDED)             Shared library: [libpthread.so.0]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
[...]

libusb-1.0.so.0 hereby belonging to dev-libs/libusbx-1.0.12.

Please change this accordingly.

Thanks!

Using hwids-20130309-r1 and /udev-198-r1, cups-1.6.1, and cups-1.5.3 fails to work with my usb Samsung ML-1450 printer, while cups-1.5.2-r4 works just fine.  I presume is has to do with hwids or udev from the other comments, but I'm not clear what to do with those.
