curve 8310 unable to connect via USB on Mac

It seems my USB port on my 8310 is inactive or broken. I have a Macbook, running 10.5.8 (Leopard).


I use the standard wall charger, so I know that the port (which also serves for the USB cord) works. 


But when I'm prompted to connect my Blackberry using the USB cord, there is no signal and it seems unable to connect.  Strangely, it detects the cord for the first 3 or 4 seconds with the "charging" icon on the Blackberry.  However, it quickly disappears and no connection is established.  I have "Desktop Manager for Mac" installed, but it is not set up - because I can't attach my Blackberry via USB for Manager to run the set-up. 


This has happened on both PCs and Macs, and multiple computers and multiple cords.  Another Blackberry user was able to update his Curve with my cord on his Mac. It's something to do with the USB port on my Curve 8310. 


I want to update my software to 4.5 (I'm currently on 4.2) and Messenger.


My "techie" friends are stumped, and I spent a while on customer service with AT&T and Blackberry.  Any help from the forum would be greatly, greatly appreciated!  I can provide additional details, if necessary.

Re: curve 8310 unable to connect via USB on Mac

As you state 8310s will connect on a Leopard MAC, it works on mine. But you can charge your from a wall outlet? I'm having an issue with my 8310, only the opposite. I can connect and charge from PC or MAC but not a 12V charger or a BB wall charger, very odd.


I suspected my BB was the problem, perhaps due to very tight voltage tolerances. After reading what you've been through it sounds like the USB ports on both of ours could be the problem.


Sorry, I can't be of any real help for you but maybe someone can help us both given this additional information.
