I have a Belkin USB dongle I use for an access point via hostapd. Here's the lsusb info: Bus 001 Device 004: ID 050d:705a Belkin Components F5D7050 Wireless G Adapter v3000 [Ralink RT2573] On fedora 14, kernel 2.6.35.13-91.fc14.x86_64 when I have it plugged in an running with my android phone connected, it gets warmish, but not too hot. On fedora 15, kernel 2.6.38.6-27.fc15.x86_64, it gets quite hot (not enough to raise blisters when I unplug it, but still noticeably warmer). In fact, I think the heat makes it shut down because I keep losing wlan0 at random times. Is there something I can tweak to fix this, or information I can provide to help understand it? I see various errors in dmesg when I plug it in, yet it does seem to be working: [162935.466041] usb 1-3: new high speed USB device using ehci_hcd and address 4 [162935.753964] usb 1-3: New USB device found, idVendor=050d, idProduct=705a [162935.753971] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber= 0 [162935.753978] usb 1-3: Product: Belkin 54g USB Network Adapter [162935.753982] usb 1-3: Manufacturer: Belkin [162935.878471] cfg80211: Calling CRDA to update world regulatory domain [162935.920599] cfg80211: World regulatory domain updated: [162935.920605] (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_ eirp) [162935.920611] (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [162935.920617] (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [162935.920622] (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [162935.920627] (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [162935.920633] (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [162936.063578] phy0 -> rt2500usb_init_eeprom: Error - Invalid RT chipset detected.
