hi! i have upgraded from nokia 6230i (i used for 6 years) to E7. i have certain problems.

To sync my contacts, photos, calander entries, messages, i had downloaded nokia ovi suite on my PC (Laptop Dell Latitude E6400) and then conected my device via USB. my device showed up on the suite and started charging and i was able to sync every thing. i did this 4 to 5 times. however now when i connect my device to my PC my device does not show up in the ovi suite but my device shows Nokia Ovi Suite- Active! i have not been able to sync via USB since. whenever i connect my device via USB to my PC a dialog box appears on my PC and shows USB device not recognised. i have tried every thing from enabling the device through Device Managar, installing drivers, uninstalling the device, reinstalling the device but the same dialog box appears again when i connect via USB. I am able to sync via Bluetooth my device shows in the Ovi suite but downloading apps, games, songs, software updates etc., cant be done.  Also for charging the device when i connect the charges it takes 4-5 times to show the charging info! and thereafter the device starts charging. I thought there might be a problem with the USB cable but it works fine with my friend's Nokia X2. i have checked the USB ports on my PC but they are also working fine with other things like USB mouse, Modem etc. I know my last resort is to visit customer care. but if any body can help me i will be realy greatful. I have the latest software version of Nokia Ovi Suite on my PC and also my device.
