    Hi all,
    is there any way to read a smartmedia card with android >= 6.0. I used an usb adaptor and usb otg cable and worked ok for android <=5 but in newer versions of android It tries to format the card (which I dont like obviously).

    thanks in advance.

    Hi Erel, the code for older versions....

    Code:
    Sub leertarjetainfo

        folder=
    ""
        
    Dim dwname As String = ""
        paths = storage.Initialize
        
    For i = 0 To paths.Size-1
            
    Log(paths.GetKeyAt(i)&"="&paths.GetValueAt(i))
            
    If paths.GetKeyAt(i)="DIRECTORY_DOWNLOADS" Then
                dwname=paths.GetValueAt(i)
                
    Log(dwname)
            
    End If
        
    Next
        
    Dim de As String = File.DirRootExternal
        
    Log ("DirRootExternal = "&de)
        
    Dim mtc As Matcher = Regex.Matcher("(/|\\)[^(/|\\)]*(/|\\)",de)
          extsdcard = de
        
    If mtc.Find = True Then
            
    Dim mnt As String = mtc.Group(0)
      
            
    Log ("mount point = "& mnt)
            
    Dim dirs As List = File.ListFiles(mnt)
            
    For Each f As String In dirs
                
    If storage.isExternalStorageRemovable(mnt&f) Then
                    
    Log ("Device = "& f&":"&mnt&f&" is removable")
                    
    If File.ListFiles(mnt&f).IsInitialized Then
                        
    Log("probably ExtSDCard: "&mnt&f)
                        extsdcard = mnt&f
                    
    Else
                        
    'Log("Problem reading "&mnt&f)
                    End If
                
    Else
                    
    Log ("Device = "& f&":"&mnt&f&" is NOT removable")
                
    End If
            
    Next
        
    End If
        
    Log("extsdcard probably="&extsdcard)
        
        folder=extsdcard 
    'revert
        
        
    For Each f As String In File.ListFiles(extsdcard)
            
    Log(">"&f)
            
    If f=dwname Then
                dwf = 
    True
            
    End If
        
    Next
        
        
    Log(extsdcard) ' this is the folder!!!!
        If extsdcard.Contains("Usb"Then
                usbready=
    True
            
    Else
                usbready=
    False
                
    ' if dwf exists revert to local folder
                If dwf Then
                    extsdcard=folder & 
    "/" & dwname
                    
    Log(extsdcard)
                
    End If
        
    End If
    End Sub
    Data (log files) is located in the root folder of the SMCard.
    Thanks in advance.

    Tested before the first email. There is a warning on the top line of the Android screen: external medium: the USB drive is not compatible and then it offers the possibility to change to a compatible format, but the card and its contents are the same, so I suppose it is a limitation of Android OS. and there is no way to avoid it.

    thanks Erel
