You should not rename the firmware file, it will break everything if you
do that. This is what you should see:

[  364.432845] usb 2-1.4: new high-speed USB device number 4 using ehci-pci
[  364.510168] usb 2-1.4: New USB device found, idVendor=0cf3, idProduct=9375
[  364.510232] usb 2-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[  364.510289] usb 2-1.4: Product: USBWLAN
[  364.510346] usb 2-1.4: Manufacturer: Qualcomm Atheros.
[  364.510430] usb 2-1.4: SerialNumber: 12345678
[  364.835598] ath6kl: ar6004 hw 3.0 usb fw 3.5.0.349-1 api 5
[  364.835710] ath6kl: firmware supports: 64bit-rates,map-lp-endpoint,ratetable-mcs15,no-ip-checksum

My first guess is that something went wrong in the kernel compilation
and the new patches are not actually applied. Double check that you
really have the new hw3.0 support in place, for example by adding few
printks and making sure that you see them in dmesg.
