我在 Ubuntu 12.04 机器上运行 ID 148f:5370 Ralink Technology, Corp. RT5370 无线适配器时遇到了问题。我已从http://www.mediatek.com/_en/07_downloads/dl.php并编译它们并激活对以下项的支持：
HAS_WPA_SUPPLICANT=y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
make 和 make install 没有任何问题。
我还将其添加到黑名单中：
blacklist rt2800usb
blacklist rt2870sta
插入设备时我得到
[ 1625.120102] usb 1-1.2: new high-speed USB device number 7 using ehci_hcd

Syslog 对此进行了一些扩展：

我还遗漏了什么？是否有任何可用的 Ubuntu deb？
