If you encounter an error “rtl sdr demod-write-reg failed with -9”, this is a common problem that you might encounter when you’re using bias tee software or command-line-based applications. The reason for this error is that the USB port does not support the features of the ExtIO API. Fortunately, there are a few things you can do to fix the problem.
If the error persists, you may need to replace the SDR dongle. You can do this by installing the new device or by manually configuring it. There are several solutions to the problem, but in most cases, the SDR dongle will need to be replaced. If the error keeps coming back, you might need to try a different dongle or purchase a new one.
To solve this problem, try using a USB 3.0 cable that is long but of poor quality. If you’re unable to find a suitable USB extension cable, try installing the device in safe mode. Some users have reported success with installing RTL-SDR in safe mode. However, if you’re getting the same error on several computers, you’re likely to have a faulty dongle.
If you can’t locate the device on your computer, you can try a different chip. The most commonly used one is the R820T, which costs only $10. Run lsmod and check the modules. Then, you’ll find rtl sdr demode – this is the same as lsmod and will give you a list of the available chips.
Another common problem with the SDR dongle is a USB extension cable with a low-quality USB port. If you’re using a USB 3.0 port, you can run the SDR demod in safe mode. You should be able to find a USB 3.0 chip by typing lsmod -rtl sdr-demod /write_reg.
The second problem with the SDR dongle is that it cannot be installed in USB 3.0 ports. If you’re experiencing this error, you should try installing the SDR dongle in safe mode. If you’re unable to install it in safe mode, then it is likely a faulty device. Alternatively, you can install the SDR driver in safe mode.
The first problem with the SDR dongle is a faulty USB connector. You can make sure that the USB port is compatible with the SDR dongle by using an extension cable. If the SDR demod command fails to write the registry, the USB cable must be properly configured. If this doesn’t work, use a low-quality USB extension cable. You can also try rebooting the computer in safe mode if the USB connection is still intact.
Often, this error is caused by a USB 3.0 port. If the USB connection is working correctly, then the RTL-SDR can be successfully installed in safe mode. If the USB port is not working, then you can try installing the RTL-SDR driver in safe mode. Afterward, you can reconnect the dongle to your computer and see if the error has gone away.
If the USB port is not functioning, RTL-SDR can cause problems with USB ports. To fix this issue, you can try to install the SDR in safe mode. You can run this command in safe mode. Then, you should check whether you have the right version of Visual C++. If you’ve tried it successfully, it’s best to use Windows’safe’ mode.
You must install the RTL-SDR with sudo. To enable the RTL-SDR, you should enable the active antenna. To configure the active antenna, you need to run rtl_tcp. In linux, you can do this by installing the DLL from the HDSDR installation directory. This will enable the active antenna. To enable the active antenna, you need to specify the DLL file.
Usually, you can use the RTL-SDR program on Windows. To use the SDR software, you must install librtlsdr. It is necessary to set the environment variable. If you want to use RTL-SDR, you can run SDR# in a terminal window. Once you’ve installed the SDR, you can run SDR# in your command-line shell.
