I have the same problem but rolling back to 3.8 wasnt possible. every time i try to uninstall 4.0 and install any older version 3.8, 3.7 etc. i cannot seem to open the Active Sync window. The little icon on the tray is there but duoble clicking / "right click open activesync" doesnt do anything.
So I'm stuck with 4.0 do to be able to sync at all. :(
Anyone figured out how to do wifi sync with 4.0 yet ?
Anyone rolled back without this problem ?

Same problem to me, so I go look the setup log and found this:

I copy from the other comp with AS 3.8 those file and it's working again. Here I attach those files. Just override the files. You must disable async from the running process first.

Use Safe Mode in Windows XP.
To extract from MSASYNC.EXE (AC3.8) use i.e.:
MSASYNC.EXE /T:C:\Temp /C

IT IS WORKING! :D

As well as all the stuff below (which I followed to the letter) I had a persistent problem when I down-graded from AS4 to AS3.8. It all worked fine, could sync and install/remove programs via USB, Bluetooth and wifi. What I could not do was browse my XDAIIi through Windows Explorer.

When I clicked on the "Mobile Device" icon in Explorer it would highlight it briefly then go back to the directory in had been using before I tried to select the XDA.

I have tracked the problem down to the USB driver installed by AS4 namely wceusbsh.sys which does not get overwritten by the older version in AS3.8.

Using XP, I did a search on wceusbsh.sys in Explorer with "Search Hidden Files" ticked and got 45 hits. There seem to be 3 versions of the file in my system:

4.0.4232.0 - this was installed by AS4 I presume
3.7.1.3244 - this was installed by both AS3.7 and 3.8
1.0.36764.0 - god knows where this came from - maybe an original when I installed XP

If you've down-graded from AS4 to AS3.7 or AS3.8 and the version of wceusbsh.sys in C:\WINDOWS\System32\Drivers folder is 4.0.4232.0 then you have a problem and it's also a pig to get rid of.

At first I tried using Device Mangler (Manager) to uninstall the 4.0.4232.0 dirver but as soon as I reloaded XP is got put back :(

Next I did an Update Driver > Select From List and manually selected the 3.7.1.3244 version but when I reloaded XP it was back at 4.0.4233.0 again - aaaaagh :evil:

In the end I had to

1. Take the XDA out of the cradle
2. completely uninstall Active Sync
3. restart XP
4. Manually delete all references to wceusbsh.sys that I could (you can't delete them all because some are in system directories and XP won't let you)
5. restart XP again - might not be necessary but I did it anyway
6. Re-install AS3.7
7. Upgrade to AS3.8

It now all works fine - even the explorer browse

BTW - i've just gone back into Device Mangler and checked the Driver details for the PocketPC USB Sync device and the Driver tab says the driver version is back at 4.0.4232.0, but if you click on the Driver Details it reports a version of 3.7.1.3244. XDA is still working fine though.

It's 3 o'clock in the morning, I give up and I'm starting to get that pain behind my eyes again... I hate Microsoft! :)

Angusmcintyre, that's some great sleuthing there bud.

Did you try using the good-old XP System Restore to roll back to your system state prior to the upgrade to AS4.0?

Codenix.

[angusmcintyre]

No too many other things have gone in since the upgrade to AS4.0 to make it worthwhile :(

[Codenix]

Yes, that's often the case. It's a shame you can't be more selective with the restore points, but that's where 3rd-party uninstallers come in I suppose.

Thanks for sharing your findings - I was planning to upgrade to AS4.0 until I read all this, which would have sucked since I only just ordered a WiFi card :lol:
