Problems of connection with pc
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.

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.

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.
