Detect Samsung Galaxy S5 phone on Win XP?

[UCyborg]

It can also happen that XP doesn't detect phone properly as media device if both USB debugging and MTP are enabled on it. If you don't mind just one feature being available at the time, the solution is easy, enable the one feature that is needed and leave other disabled.

If both are desired, there is a trick that works. When both are enabled, you'll initially get MTP entry in Device Manager with exclamation mark and the error that device isn't configured.

1. Open said MTP entry, go to Details tab, select Device Instance ID, leave the properties window open.
2. Launch Registry Editor (regedit.exe), navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB.
3. Refer to the value sown in the MTP properties window you've opened in 1. step to know where exactly you should navigate from USB onward.
4. Right-click on the key you've just navigated to->right click->Permissions...->make sure Everyone is selected->tick the checkbox at Full Control/Allow, confirm the new settings.
5. On the right-pane, open CompatibleIDs entry with a double-click, then insert USB\MS_COMP_MTP at the beginning. Should work fine if added to the end, but this particular ID is usually at the beginning.
6. You may undo permissions changes from 4. step; when you open Permissions window, make sure Everyone is selected, click Remove (the checkbox at Full Control/Allow should be gone now) and confirm.
7. Back to the Device Manager MTP Properties window, you may trigger driver update from the Driver tab. If it asks about searching for the driver on Windows Update, say No, not this time, then let it detect it automatically (Install the software automatically option).

Thanks UCyborg, I will try this as soon as I fix an unexpected hardware problem that happened to me.
