I can't say enough how awesome this info is. For someone who uses ONLY usb drives/devices for my music, this is good news. So far I have had no success trying to use a variety of small usb hubs.

USB Hubs will not work....The Sync operating system does not include the ability to load the correct drivers for the hubs.

"USB Hubs will not work....The Sync operating system does not include the ability to load the correct drivers for the hubs. " 

Hubs are "dumb" devices.  They do not require drivers.  However, when two devices are hooked up to a hub, Sync can't distinguish which device to use.  Or it may just pick the first device it detects and use that. 

I'm pretty sure the microcontroller in the SYNC module only supports USB On-The-Go (OTG), which is the cause of the hub issues.  The complete explanation of OTG can be found at this link.  However, if you don't want to click through, the relevant excerpt is below:

"USB On-The-Go does not preclude using a USB hub, but it describes Host/Peripheral role swapping only for the case of a one-to-one connection where two OTG devices are directly connected. If a standard hub is used, the supplement notes that using it will lead to losing USB OTG role-swap capabilities, locking one device as the Host and the other as the Peripheral until the hub is disconnected."

And since SYNC locks to a single device (i.e., one of your media devices on the hub), the others are not accessible.

USB1 is OTG.  USB2 is not.

Ahh, great info.. thanks Mike. :)

Hubs are not passive and still require drivers...They have an internal chip that the PC (or in this case Sync) must communicate with to access the devices connected to it. Trust me, I design USB devices for a living.

Great info thanks !

Would love to use the USB2 connection for my USB stick or hard drive, while reserving the USB1 for charging, ipod, etc....

Anyone know where the USB2 port is on the 2010 Mustang ?

Thanks

I have a 2009 Escape and am looking at ways to use the USB2 connection. Before I dig into the installation, can someone tell me- are there limitations to the funcionality or the commands that are used with the USB2 input. I'd be using it mostly with a thumb drive. Seems like I read that somewhere, but I can't find anything on it today.

Any info would we appreciated. Thanks all!

I only use USB2 and all Sync commands work flawlessly with my 16GB USB flashdrive.
