 I have similar issue. My card:
 
 rum0: <Ralink 802.11 bg WLAN, class 0/0, rev 2.00/0.01, addr 6> on usbus6
 rum0: MAC/BBP RT2573 (rev 0x2573a), RF RT2528
 
 I also see my clients disconnect quickly.
 However, mine one do not send out any beacons.
 I'm also using hostapd, and as I capture the packets in the
 IEEE802_11_RADIO layer from an internal intel 3945 card, I cannot see
 any beacons sent by the card.
 I can see beacons of other access points, and if I plug the Ralink
 card into a WinXP laptop with official driver and software installed,
 I can see beacons from the card.
 So I think that the hardware is capable of sending beacons. It's just
 a problem of the driver.
 
 I found that though there is no beacons, a windows laptop connects
 fairly stable to the network. Maybe it ignores the beacons.
 However, my phone always disconnects from the network. It is an
 android phone, which uses wpa_supplicant to manage wireless
 connection.
 
 I create my wlan device with this:
 # sudo ifconfig wlan0 create wlandev rum0 wlanmode hostap
 My hostapd.conf:
 
 interface=wlan0
 ctrl_interface=/var/run/hostapd
 wpa=1
 wpa_passphrase=xxxxxxxxxx
 ssid=henryhu
 
 By the way, I found that the beacon_int and channel in hostapd.conf is
 useless, is it true?
