Bug 155759 – Libifp does not works for user with libusb 0.1.12.

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Piotr Gabryjeluk 2006-11-20 05:42:23 UTC]

Libifp (for the iRiver devices) does not allows to connect to a regular user (in group ifp). Root however is allowed:


quake@deuteranoptic ~ $ ifp ls
Device is busy.  (I was unable to claim its interface.)
quake@deuteranoptic ~ $ sudo ifp ls
Password:
d VOICE
d RECORD
d Octavarium
d Second Life Syndrome [FLAC]
d Opeth - Morning Rise
d A Change of Seasons
d Utopia Banished (PREVIEW_ buy it at www.magnatune.com)

When emerging =dev-libs/libusb-0.1.11 instead of 0.1.12. User being in ifp group can connect (using ifp, ifpgui, ifp-gnome and Amarok).

It looks like /usr/share/ifp-line/nonroot.sh works well in both cases, because after connecting an iRiver device to the USB port I get something like this:

quake@deuteranoptic ~ $ ls -l /proc/bus/usb/*/
/proc/bus/usb/001/:
razem 0
-rw-rw-r-- 1 root usb 43 lis 20 14:14 001

/proc/bus/usb/002/:
razem 0
-rw-rw-r-- 1 root usb 43 lis 20 14:14 001
-rw-rw-r-- 1 root usb 73 lis 20 14:14 003

/proc/bus/usb/003/:
razem 0
-rw-rw-r-- 1 root usb 43 lis 20 14:14 001

/proc/bus/usb/004/:
razem 0
-rw-rw-r-- 1 root usb 43 lis 20 14:14 001
-rw-rw-r-- 1 root ifp 50 lis 20 14:36 004

But when libusb is in version 1.1.12 user still can't connect.

I do not know whether this is a bug in libusb or in libifp or in the interaction between the two.

Temporary solution is masking the new libusb:

As root:
echo =dev-libs/libusb-0.1.12 >> /etc/portage/package.mask/libusb
or if package.mask is a file:
echo =dev-libs/libusb-0.1.12 >> /etc/portage/package.mask

Using libusb version 0.1.11 everything works as expected.

See bug #131756 :)

yeah, i really dont think this is a libusb bug ... more likely a dupe of that
