Problems of connection with pc

[Eduardo07101998]

help!!
I have problems with the connection of the nano vna saa v2 pro with my pc (windows 10), I already installed the driver (CypressDriverInstaller_1) but it appears as an unrecognized device.

I bought the LTDZ V2pro, But it also didn't recognize the USB on my PC.
When I checked, the DP/DM signal was swapped on the pattern.
Probably a mistake in selecting the USB receptacle(Type-C).
So I cut the pattern and swapped the DP/DM signal.
After repairing the USB DP/DM swap, I was able to update to 20201013.

As for my item, MXD8641 (SW_PORT2) was also defective.
The noise floor of CH1:LOGMAG is bad and it is useless.
I am currently ordering a replacement part.

@Eduardo07101998 ...

hallo,

did you solve your problem? if yes, how? I have the same problem

Hello,

Are you talking about LOGMAG noise?
I failed to replace MXD8641.
So I bought another cheap S-A-A-2, which is less noisy.
I think S-A-A-V2Pro has poor performance just because the LCD is large.

hi Gorgen-japan,

sorry, no. I was talking about the connection between my SAA V2Pro and my windows computer. The same identical problem that Eduardo said in the first post.
Anyway thanks,

Lorenzo

Sorry , it's my mistake.
The problem with USB is a bug where the data signals are swapped.
The solution is to modify the board or modify the USB cable.

You only have to swap the data pin D+ and D- and you are going to have conectivity with your PC. I'll be looking foward for your comments. Best Regards. Obtener Outlook para Android<https://aka.ms/AAb9ysg>

really many thanks to gonger-japan and Eduardo07101998.
The solution was exactly what you told. Changing D+ and D- in the USB cable.

Many thanks.
