[fuse-devel] Fusermount crash?

[Matt D. <li...@al...>]

Hi,

Running kernel 2.4.29, on a Debian machine with fuse-2.3.0, libusb-0.1.10a
and owfs.

When trying to mount OWFS via a USB device, it appears that fusermount broke
:-(

Am I coming to the right place? Or is this libusb/owfs related instead?

Thanks,

Matthew
