bug#57044: 29.0.50; tramp-error: Reading directory: Permission denied, /scp:motorolausb:/storage/emulated/0/

[Jean Louis <bugs@gnu.support>]

I have compiled latest Emacs Version.

I did this:

(add-to-list 'tramp-remote-path "/data/data/com.termux/files/usr/bin")

(add-to-list 'tramp-remote-path "/data/data/com.termux/files/usr/bin")

(setq tramp-verbose 10
      tramp-connection-properties '(("scp:motorola" "tmpdir" "/storage/emulated/0/tmp") ("ssh:motorola" "tmpdir" "/storage/emulated/0/tmp")))

Error is that it cannot find `ls' command. I had never problems with
it before.

Problem is with scp method. 
============================

If I use ssh method, I can enter. I can enter with rsync method.

If I use scp method, with the above information, I get missing `ls'
command.
