[PATCHes] Patches for OpenObex

[-- Attachment #1: Type: text/plain, Size: 512 bytes --]

Heya,

2 small patches for openobex.

The first patch fixes libusb1 compilation on my machine.

For the second patch, when libusb1 is used, we can set self->fd to be a
monitoring file descriptor for incoming data.

With that patch, I could make osso-gwobex work with USB connections.

There's still some bugs to take care of, but I believe this patch to be
correct. Are there any places in openobex where the self->fd will be
directly when connected via USB? If so, those would need to be fixed as
well.

Cheers

Subject: [PATCH 1/2] Fix libusb1 detection

There's no need to check for the presence of a .pc file in
/usr/lib/, pkg-config will already do that for you, and it would
fail on machines where /usr/lib64 is used, or when libusb1 is
installed in another prefix.

Subject: [PATCH 2/2] Export the libusb1 read file descriptor

When using libusb1, we can export the file descriptor that
corresponds to reading from the device, so it can be used to
setup polling sources, and timeout based operations.

This would be used by osso-gwobex to monitor incoming data, for
USB support.
