DeviceHandle does not work for all devices [#11993]

[ceinj]

MM 4.1.0.1629 on XP and Windows 7. I have a vbs script that uses the new DeviceHandle call but it doesn't report many connected devices. I had an iPhone, HTC (Android) and a Thumbdrive connected to the computers. MM showed these devices in its tree but only the DeviceHandle for the iPhone returned a value other than -1.

Also calling the function/property takes a long time (just a precautionary warning to scripters).

You seem to be right,
it works for my Android phone in MTP mode, for iPhone, but doesn't work for my USB stick (with assigned drive letter), I guess this is case for your devices?

I will fix it as http://www.ventismedia.com/mantis/view.php?id=10708

Yea! The new version fixes the problem and seems to be much faster.

Thanks!

New issue found. Running version 4.1.0.1664. I plug in an Android phone and two devices show up in MM (phone and SD card). I verified I can sync to both devices using MM manually. When I try writing a script it seems that there is only a single "DeviceHandle" for this device and there is no way to copy to the SD card.

Hi, so if you use example code here http://www.mediamonkey.com/wiki/index.p ... viceHandle to enumerate them then only one device is in the list?
i.e. SD Card and Phone have same VID and PID, but if you use something like (with your device VID/PID)

Code: Select all

Dim Devices : Set Devices = SDB.Device.ActiveDeviceList("VID_04E8&PID_6860")

then

Code: Select all

Devices.Count = 2

, isn't it?

Both examples seem the same! They both return a device count of 2 but only 1 has a valid DeviceHandle.

Strange, I don't see a reason for it.

So both SDCard and Phone are returned in the list, but SDcard has DeviceHandle = -1 ?
Which phone model it is?
If you try to initiate playback of tracks on the device from MM interface (Media Tree -> SD card -> Music...), do they play?

[ceinj]

The phone is a Samsung Galaxy Victory 4G LTE. In MM I have been able to copy different selections to the phone and the SD card and verified playback.

To clear up any misstatements I may have made, I wrote a small script to dump the device handle and other device information. Code snippet and results are below.

Code: Select all

  Dim list : Set list = SDB.Device.ActiveDeviceList("VID_04E8&PID_6860")
  If list.Count = 0 Then
    Call SDB.MessageBox(SDB.Localize("No active devices. [1]"),mtError,Array(mbOk))
    Exit Sub
  End If
  
  Dim inds : inds = ""
  Dim nams : nams = ""
  Dim boo : boo = False
  Dim txt
  Dim i : i = 0
  For i = 0 To list.Count-1 
    txt = ">>Dev " & i & " ID [" & list.DeviceID(i) & "] Device Count = " & list.Count & " Handle [" & list.DeviceHandle(i) & "]"
    Call fout.WriteLine(txt)
    If list.DeviceHandle(i) > -1 Then
      Dim indx : indx = list.DeviceID(i)
      Dim sqls : sqls = "SELECT DeviceCaption,DetailedUSBID FROM Devices WHERE DetailedUSBID LIKE '%"&indx&"%'"
      Dim iter : Set iter = SDB.Database.OpenSQL(sqls)
      While Not iter.EOF  
        txt = "  Detail Caption [" & iter.StringByIndex(0) & "]"
        Call fout.WriteLine(txt)
        txt = "  USB ID [" & iter.StringByIndex(1) & "]"
        Call fout.WriteLine(txt)
        iter.Next
      Wend
      Set iter = Nothing
    End If
  Next 
  Call fout.Close()

========== Results Below =============

OK, so the issue is that the (Device Count = 1), I should have similar phone for testing next week so I am going to see If I can replicate.

This should be better handled in 4.1.10.1765
