Using AD9361 FMCOMMS/2/3/4 question.

I ran successfully my RADIO AD9361 using matlab older version.

In my computer I installed virtual machine and it changed by setup


Now I have changed to R2020b version of Matlab and try to run my radio

with the WLAN transmission and receiving matlab code. I get the error as follows:

Failed to find device: cf-ad9361-dds-core-lpc

I also checked my Linux machine and found that under the following directory,

/sys/dev/    no more iio directory.

Even though I installed libiio again.

If I use the following on my terminal:

grep -e ^open  foo | grep libiio

I get the following response:

openat(AT_FDCWD, "/usr/lib/x86_64-linux-gnu/", O_RDONLY|O_CLOEXEC) = 3

However, according to the instruction it should be as follows:

open("./tls/x86_64/", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("./tls/", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("./x86_64/", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("./", O_RDONLY|O_CLOEXEC) = 3

Can someone explain to me what is going on with my Linux machine?
After using virtual machine, the setup has changed.
What must I do to run the AD9361 radio successfully?
