RTL SDR dont work on Asus Prime B350 Pluse + Win7 x64

[DX888]

Hello! I wanted to buy RTL-SDR V3, but I suspect that it will not work in my computer. And that's why.

I have USB 2.0 Digital DVB-T SDR+DAB+FM HDTV TV Tuner RTL2832U+R820T https://www.aliexpress.com/item/Univers ... 08603.html And it does not work on my computer.

now in order.

1. main PC: AM4 Asus Prime B350 Pluse, Ryzen 5 1600, Win7 x64 sp1

2. Im install Zadig driver - all ok (i send log of instal to Pete(Zadig dev), he sad that driver install good). Here is his answer

Code: Select all

"Sorry but I don't do SDR software support.
Your log shows that the WinUSB driver was successfully installed:
> WinUSB USB device (9): USB\VID_0BDA&PID_283 8&MI_00\7&38A180A5&1 F&0000

So if the SDR software can't see it, then it's an SDR software problem,
and it has nothing to do with Zadig.

Sorry,
/Pete"

3. But no any sdr-soft dont see dongle. (try HDSDR, SDRSharp, SDRConsole (V3))

What i do:
- try use this dongle on another PC whith Asus AM3 M4A78T-E + the same Win7 x64 sp1 - all ok, all sdr-soft see the dongle, he is work.
- try install Win10 x64 to main PC AM4 Asus Prime B350 Pluse, Ryzen 5 1600, - all ok, all sdr-soft see the dongle, he is work.

What i do to main PC:
- install last Bios (4207) - no result
- install last drivers - no result
- download and install all versions of Zadig - no results
- reinstal Win7 x64 - no results
- install all neded soft (NetFrimework 4.7.2, Visual C++ and etc) - no results
- try instal dongle to USB 3.1, 3.0, 2.0 - no results
- try turn off in Bios all 3.1 and 3.0 USB porst - no results
- try instal another Zadig WinUSB drivers - no results


So that is a problem in a bunch of Win 7 x64 + the motherboard AM4 Asus Prime B350 Pluse. What other ideas could there be?

the USB ports are in the Ryzen chip, not the southbridge.. Thus WIn 7 does not support them..
Ryzen chip set needs win10 for full functionality.

Probably a USB issue on your ASUS as it works on other PCs, but just checking, did run install-rtlsdr.bat and make sure the rtlsdr.dll file is in your SDR# folder?

If the cheap dongle is not working on that PC, then neither will the V3.

Check the install-rtlsdr.bat that is on your site https://airspy.com/?ddownload=3130 , it is damaged. Zadig file dont downloads. However, I downloaded all the files manually, nothing helped. And yes rtlsdr.dll in folder but sharp dont see dongle:



But! If i install Win10 on main(this) PC - all work.

Problem solved. Comprehensive information.

If you have a modern motherboard based on Ryzen, Intel, USB 3.0, 3.1 processors, you also have Windows 7 x64 and your RTL SDR receiver is not detected by HDSDR, SDRSharp (No RTLSDR device found or No device selected) - download this archive and follow the instructions.

The install-rtlsdr.bat file isn't damaged, those % signs are normal and meant to be there. Maybe your antivirus was blocking it though?

This ACTUALLY WORKED for me! This is a blessing I really strongly prefer SDR# to CubicSDR. I can't believe nothing else worked. There should be fixes for new Mobos/CPUs added to the main repo!

You can use these DLL files: viewtopic.php?f=1&t=4710&start=20#p11796

it will solve your issue. This is known bug of libusb library which happens on modern motherboards.
The archive contains rtlsdr.dll which is compiled with a fresh RC libusb with fixed bug.

for SDR# you're needs rtlsdr.dll from archive, for HDSDR both dll

Anyone got info on exactly what is changed in these drivers to make it work for these certain motherboards?
