Any idea if a Linksys WUSB54GR will work to replace the internal Atheros 5424/2424 doesn't

[eculp]

I am looking to substitute the Atheros 5424/2424 with a linksys WUSB54GR.

Any idea if it will work on the following laptop?  Of course if you  
have an idea for getting the internal wireless to work it would be  
great too.

Thanks,

On an Acer 5520/5679 laptop, I don't see a way to get wireless  
working.  I'm running:

8.0-CURRENT-200712 FreeBSD 8.0-CURRENT-200712 #0: Sun Dec 30 11:33:37 CST 2007

The dmesg shows it detected but can't attach:

ath0: <Atheros 5424/2424> mem 0xf2200000-0xf220ffff irq 19 at device  
0.0 on pci5
ath0: [ITHREAD]
ath0: unable to attach hardware; HAL status 13
device_attach: ath0 attach returned 6

pciconf -lv shows:

ath0 at pci0:5:0:0:        class=0x020000 card=0x04281468 chip=0x001c168c  
rev=0x01 hdr=0x00
     vendor     = 'Atheros Communications Inc.'
     device     = 'AR5006 family 802.11abg Wireless NIC'
     class      = network
     subclass   = ethernet

Is there something else that I can do?  If you can confirm that this  
isn´t supported,If anyone knows of a list of 802.11 usb solutions that  
work with amd64  would also be appreciated.

Thanks for any help,
