Thanks for porting the driver.
I tried it with a TRENDnet TEW-504UB/EU on CURRENT as of today.
But there are a couple of problems with that device:
1. Different product ID
My TEW-504UB/EU becomes 0x3207 after loading the firmware. OK, this one is
easy to fix:

I don't know why this device has another product ID with a loaded firmware,
but perhaps because it is an 802.11a capable device?
BTW: the vendor's firmware leads to the known ID (0x3205), but uath bails
out:
uath0: timeout waiting for reply to cmd 0x1 (1)
uath0: could not initialize adapter
device_attach: uath0 attach returned 35
uath0: timeout waiting for reply to cmd 0x1 (1)
uath0: could not initialize adapter
device_attach: uath0 attach returned 35
ugen4.2: <Atheros Communications Inc> at usbus4 (disconnected)
ugen4.2: <Atheros Communications Inc> at usbus4

So, now to the second problem:
The device works like a charm in 802.11b/g mode (ifconfig wlan0 chanlist
1-13) with FreeBSD's firmware.
But 802.11a scanning does not work. Without the chanlist restrictiong, I get
the following messages:
(plug in the device)

(ifconfig wlan create wlandev uath0)

(ifconfig wlan0 up)

  uath0: could not switch channel
I'd like to provide additional debugging information. If you need more,
please tell me what.
BTW: Could you add a message declaring the device when it is plugged in?
Something like "uath0: <TRENDnet TEW-504UB wireless LAN adaptor> on usbus?"
and "uath0: ether aa:bb:cc:dd:ee:ff"?
Kind regards,
Lucius
