802.11n USB

I've purchased and RT5572 WLAN card from Mediatek. The card is supported for Linux in two ways:

1. A driver available with the Kernel itself.
2. A driver from Mediatek themselves.

The problem is, that both won't run stable ony my system (ARM-based). I did compile both of the drivers, but none shows the stability, that I wish for. The Mediatek driver even refuses to work absolutely.

Therefore my question: Is there any hardware available, that suits the following needs?

- USB connection (must have)
- 2,4 / 5 GHz dualband (must have)
- 802.11n standard (must have)
- external antenna connectors (must have)
- low power consumption - embedded module
- all channels (even the DFS ones) available - free choice of frequencies
- no housing, pure PCB-board

Any hints would be kindly appreciated.

Thanks in advance,

With ARM it's sometimes difficult, I have an embedded design based off of the AM335x Cortex-A8 (came from the Beaglebone design) and we use an ASUS EZ N adapter, with the Realtek RTL8188S chipset in it. USB-N10. Here's someone else's experience with it Quick Test ASUS USB N10 WIFI Adapter Under Linux.

You have to use 2.6 or better, I'm using Angstrom 3.8 and have no problems with it.

I notice you mention "no housing" Well, we tear it apart because we shove it inside another enclosure; sorry but they come with the plastic enclosures on them, we break or cut that off.
