UHD USRP设备欠缺行为能力(UHD USRP device lacks capacity)

我使用的是一个CentOS 6.5的机器64位和USRP B100与UHD驱动3.7.2红鹰1.10.0。 USRP的B100被系统正确识别。这是一个USB设备。我下载的版本的最新版本UHD_USRP设备的。 3.0红鹰和我创建包括GPP和UHD_USRP设备节点。启动节点没有任何问题，但是当我运行一个简单的波形来读取USRP数据作为RX_DIGITIZER我得到了以下错误：

哪里是我的错吗？在此先感谢您的帮助。

该frontend_tuner_status结构顺序是什么定义了设备的能力和容量。如果序列是空的，分配总是会导致能力不足。空frontend_tuner_status属性通常是不指定目标设备，或不能够找到指定的目标设备的结果。

您必须指定使用TARGET_DEVICE结构属性的目标设备。这可以在节点内或在运行时进行。所述USRP_UHD红鹰设备的先前版本只允许使用属性被指定的IP地址，但是为了支持USB连接的（和一般的，非网络连接）USRP设备，这已被替换为TARGET_DEVICE结构属性。

所述TARGET_DEVICE属性允许用户指定IP_ADDRESS， 名称，序列，或类型，并且将使用满足标准，如果发现所述第一USRP硬件设备。应该在TARGET_DEVICE结构被指定的信息可以由update_available_devices属性设置为true，导致available_devices结构序列与所有发现的设备（由命令行工具报告的相同的设备和信息填充确定uhd_find_devices ）。

以确定是否USRP_UHD红鹰装置被连接到目标设备，检查属性。具体地，如果未链接到一个硬件设备，以及所述device_motherboards和device_channels属性frontend_tuner_status序列将是空的。
