Sync your Windows Mobile 5.0 device via USB on your Mac

As I have discussed here on my blog, I am really enjoying Parallels WorkStation on my MacBook Pro and one of the only reasons I wasn’t completely able to remove the Apple Boot Camp partition was USB support to allow me to sync my mobile devices. While testing the alpha of The Missing Sync for Intel Macs and Windows Mobile 5.0 devices I found a utility loaded on my i-mate SP5m called USBSwitch. This utility allows you to switch the way the USB connection is made from the default RNDIS mode to Serial mode. Once I made the switch then I was able to sync perfectly using The Missing Sync in Mac OS X. I then thought this may work in Parallels WorkStation since the problem there now with Windows Mobile 5.0 devices is that a network connection is trying to be made and multiple network connections don’t seem to be supported. I then switched modes on my i-mate SP5m, started up Parallels Workstation and then connected my USB cable. Voila! I was syncing my device via ActiveSync 4.1 to the virtual Windows XP environment and am now a happy camper. I then did some digging around and found the .cab file for USBSwitch over at the XDA Developers site and installed it on my i-mate JasJar (most Windows Mobile devices don’t have it preinstalled) and now I can sync that device as well.

I am posting USBSwitch here for anyone else who wants to give it a try. I don’t offer any guarantees it will work or any warranties if something happens to your device and am just passing along a useful tool I found and want to share.

    Thanks for posting USBSwitch on your blog! Somehow I can’t get to it anyway else (I have a Mac-only environment 😉 ) As I have spend evenings on end to get the alpha Missing Sync to work and finally did’nt I was already contemplating using another PIM altogether, but this seems to work!

    Thanks again!

    How did you get this to work through Missing Sync? Are you referring to the beta version for WM5 Missing Sync sw? Please let me know as I am losing my mind on how to get it to sync without tons of errors and dupes.

    I am testing out the Alpha version of The Missing Sync. It has worked fairly well for me so far.

    I’ve just installed USB Switch in an O2 Atom Exec. Program loads, switched to serial and then Missing Sync doesn’t recognise the PDA. Switch back to RNDIS and immediately connect (with VERY slow sync). Any ideas? Btw, Bluetooth sync works but is not that much faster than USB RNDIS. This will be great if it works.

    The developers of The Missing Sync emailed me and there is a brand new update to the program that fixed many USB issues people were having. It should work now on your Mac without having to worry about using USBSwitch at all.

    Dude, you rock! Thanks for all this. I found your post on the Parallels Desktop Mac forum, then Googling for “USB Switch” sent me here.

    FYI, I used it successfully on my MacBook Pro 17″ with Parallels Desktop Build 1848, with a Sprint PPC-6700 and ActiveSync 4.2.
