Ubuntu 14.04 AWUS036H (v5) 不断重新初始化 - 从未完全成功

我在 Dell Precision M3800 上运行着 Ubuntu 14.04。我需要在这台机器上使用两张 wifi 卡（说来话长），并且我已经让内置 Intel 7260 与 Netgear 等（rtl8187 芯片组）一起工作了相当长一段时间，没有任何问题。

我决定用 AWUS036H 替换 Netgear，因为它使用相同的芯片组并支持辅助天线。

然而，插入 AWUS036H 后，我在系统日志中看到了以下内容：

这种情况会无限循环，导致设备永远无法使用。

我已经完全删除了网络管理器，但这没有用。我删除了 7260 驱动程序并将它们列入黑名单，但这没有用。我将其插入另一个 14.04 盒子，其中没有其他无线网卡，它可以正常工作。

这是 lshw 的输出（如果我的时间恰到好处，我可以接收到 AWUS，但它只会列出片刻，然后就会消失）：

有什么想法吗？我有点不知所措，尤其是因为另一张使用 rtl8187 的卡在这台笔记本电脑上运行良好。

谢谢！
