Allocated tap interface: tap0

On other console:
yume$ su
yume# dhclient tap0
yume# cat /var/db/dhclient.leases.tap
...
option routers XXX.XXX.XXX.XXX;
option domain-name-servers YYY.YYY.YYY.YYY;

yume# route delete default
yume# route add default XXX.XXX.XXX.XXX
yume# echo nameserver YYY.YYY.YYY.YYY /etc/resolv.conf
Tested on FreeBSD 8.0-RC2 i386; modem Samsung SWC-U200.
Usually works fine (ping normal - less than 1% packet loss; http ok)
Sometimes crashes in libusb:
yume# ./madwimax
...
Allocated tap interface: tap0
zsh: segmentation fault (core dumped) ./madwimax
yume# gdb ./madwimax madwimax.core
GNU gdb 6.1.1 [FreeBSD]

Near libusb10.c:1116:

Near libusb20.c:258:
257 void *
258 libusb20_tr_get_priv_sc1(struct libusb20_transfer *xfer)
259 {
260 return (xfer-priv_sc1);
261 }
Because of pxfer0-priv_sc1 is NULL from core dump, I think that it is
a libusb implementation bug.
PS:
Also I've commented this call at wimax.c:847:
847 //libusb_cancel_transfer(req_transfer);
because of segmentation fault when program going to terminate.
(this is inside exit_release_resources() function)
