Hello,
   i'm using Archlinux image 3.7.1 and TP Link Usb wifi dongle (TL-WN722N). I'u using the same SD card with linux image and my system is working correct with Rev. D hardware, but with Rev. E hardware it is not working. ip link set wlan0 command responds with "Cannot find device wlan0", bus lsusb shows Atheros usb device. What can cause this problem ? In documentation there was no significant changes is hardware.

I've checked with newest image, the same.

Rev. E shows firmware download error after connecting USB WIFI:

the same SD card with Rev. D works fine.
