Bugzilla Bug 159931

This might be a bug with fxload, or one with linux-headers. When attempting to
compile with linux-headers-2.6.19 the following error occurs (compilation works
fine on 2.6.17-r2).

The Error:
cc -c -O -Wall -march=athlon64 -O2 -pipe -fomit-frame-pointer  ezusb.c -o
ezusb.o
ezusb.c:32:25: error: linux/usb.h: No such file or directory

no interest in this package ... it needs to be rewritten to use libusb

$ pquery --raw --revdep=sys-apps/fxload
media-sound/usbmidi-1.0 - sound
media-tv/wis-go7007-0.9.8 - beandog/media-tv

Anyone interested? If not, well the above ebuilds will have to go sooner or
later. 

Plus sys-apps/fxload depends directly on hotplug, which makes both of the above
ebuilds depend on it as well. udev handles firmware loading on it's own since
096 (see Bug 138126) and hotplug makes firmware loading pretty much broken (Bug
147006) 

In terms of dependencies, it might be worth noting here that you need this to
load the first stage of the firmware of Tascam USB soundcards (those using the
snd_usb_usx2y driver) before using the alsa-tools usx2yloader for the second
stage.

There don't seem to be package dependencies around this usage, but removal of
fxload from the tree will prevent the use of these sound cards - udev doesn't
seem to cope on its own.

Well, as said on this bug, the thing doesn't compile against
linux-headers-2.6.19, which will eventually go stable. Plus it's totally dead
upstream, has no Gentoo maintainer and the design sucks. :) Patches are
welcome, otherwise it will become useless and die sooner or later.

Fair comment. I shall look at a patch when I can though I don't anticipate
great success. In the meantime I will let the ALSA list know there might b an
impending problem.

Removed dependency to sys-apps/hotplug.
Fixed compilation (just need to change linux/usb.h to linux/usb_ch9.h)
