can you try to rebuild the module with URTW_DEBUG enabled, then set
hw.usb.urtw.debug to any of the state in the following enum:
enum {
URTW_DEBUG_XMIT =3D 0x00000001, /* basic xmit operation */
URTW_DEBUG_RECV =3D 0x00000002, /* basic recv operation */
URTW_DEBUG_RESET =3D 0x00000004, /* reset processing */
URTW_DEBUG_TX_PROC =3D 0x00000008, /* tx ISR proc */
URTW_DEBUG_RX_PROC =3D 0x00000010, /* rx ISR proc */
URTW_DEBUG_STATE =3D 0x00000020, /* 802.11 state transitions */
URTW_DEBUG_STAT =3D 0x00000040, /* statistic */
URTW_DEBUG_INIT =3D 0x00000080, /* initialization of dev */
URTW_DEBUG_TXSTATUS =3D 0x00000100, /* tx status */
URTW_DEBUG_ANY =3D 0xffffffff
};
to see if anything useful pops up ?
Thanks,
