How does the SYNC feature of Windows Portable Device works?

NTDEV
1

Hi All,

As discussed earlier we were trying to redirect USB devices over IP and I
have a quick clarification on how exactly the MP3 Player when connected
Windows Media Player is able to SYNC it without any issues? But when we
redirect these MP3 Players they are not being detected by Windows Media
Player, where as these are being detected as normal disk drives.So any
suggestions or any help would be of great help.

Thanks in advance.

We already answered this question for you five months ago. You aren’t populating your compatible IDs correctly. Go read the old thread again.

Chris,

You are correct that this was answered earlier with regard to UMDF
Drivers…But now when I tried a MP3 Player from Sandisk Sansa which is not
associated with WPD/UMDF type of devices and it neither supports Microsoft
OS Feature descriptor.

This player just installs USBStor driver and the H/W compatible id’s are as
below:

USBSTOR\Disk
USBSTOR\RAW

Even then when I open the media player and try to use the option “sync” it
works.

But when we redirect this same player onto the same machine where we were
able to sync it, it doesn’t get recognized by Media player. It just
recognizes as a normal disk…

Thanks in advance.

Maybe you’ve got a Sansa model with dual interface
(for exampe “E” series) - it can appear to the host
as plain USB drive or MTP device, depends on
it’s setup menu choice.

Vishwanath, it means, look in the setup menu of the player.
If it has MTP mode, switch it ON.
Then WMP will handle it as a media device, with sync and so on.

He’s saying it only shows up as mass storage (not MTP) on both machines, but yet the sync operation is still supported on one of them (the “host” machine).
