When I plug my BB into the USB port I get that message and "verify that your handheld is connected to a powered usb charging source and the proper drivers are installed. I have been using this port for months and never had a problem - why is this happening???
I had a 8700 with desktop 4.2 - when I received my 8800 on Cingular 5/2007 - I used their software. I did not realized that it was 4.1. They probably packed it up a year ago! I just uninstalled their 4.1 and rein. 4.2 and the issue went away. One has to wonder about the products we receive. I sure it was new but when was it made and just held off the market for a good release date.
should be the power savings setting on the USB port:
go to control panel=>System=>Hardware=>Device Manager: click on Universal Serial Bus Controllers => and in all USB Root Hub => right click => Properties => Power Management and uncheck => allow the computer to turn off this device to save power.....
