This is my setup这是我的设置

Raspberry PI4 with 8 GB RAM;覆盆子 PI4 配备 8 GB 内存； boot via Sata SSD (in enclosure) connected via USB3通过通过 USB3 连接的 Sata SSD（在机箱中）启动
1 USB2 extension cable + Hub which goes to 1 RTLSDR dongle (for ADS-B) and 1 Airspy Mini (for ATC communication). 1 根 USB2 延长线 + 连接 1 个 RTLSDR 加密狗（用于 ADS-B）和 1 个 Airspy Mini（用于 ATC 通信）的集线器。 The ADS-B dongle is obviously running all the time with piaware while the Airspy Mini is only used when I tune in to listen to something so...not often. ADS-B 加密狗显然一直在使用 piaware 运行，而 Airspy Mini 仅在我调谐收听某些东西时使用......不经常使用。
1 USB2 cable which goes to a third RLTSDR v3 used to capture satellite on a certain schedule. 1 根 USB2 电缆连接到第三个 RLTSDR v3，用于按特定时间表捕获卫星。

The two RTLSDRs can run at the same time without issues.两个 RTLSDR 可以同时运行而不会出现问题。 However, if I try to also run the Airspy Mini (that is, tune into a frequency) while the others are running (could happen as I don't realize if there is a satellite pass at the same time) then the raspi makes a weird high pitch noise and It basically freezes.但是，如果我尝试在其他人正在运行时也运行 Airspy Mini（即调谐到一个频率）（可能会发生，因为我不知道是否同时有卫星通过），那么 raspi 会产生一个奇怪的高音噪音，它基本上冻结了。 I get I/O errors and I cannot do anything as no command is found: I guess the SSD just disconnects itself from the USB. Only way to fix it is to restart.我收到 I/O 错误并且我无法执行任何操作，因为未找到任何命令：我猜 SSD 只是断开了与 USB 的连接。修复它的唯一方法是重新启动。

Is this related to the USB bandwidth?这与USB带宽有关吗？ I thought the Raspi4 was capable of handling these simultaneous connections.我认为 Raspi4 能够处理这些同时连接。

1 个解决方案

The problem was power-related.问题与电源有关。 Once I introduced a powered USB Hub I never encountered this issue again.一旦我引入了一个供电的 USB 集线器，我就再也没有遇到过这个问题。
