Hi and Welcome to the Forums!
Here is the list of troubleshooting articles...hopefully something will be useful:
KB02640 Troubleshooting USB connections
KB15486 Top 10 BlackBerry smartphone and BlackBerry Desktop Manager troubleshooting tips
KB00125BlackBerry Desktop Software cannot detect the BlackBerry smartphone
KB11439 BlackBerry Desktop Software does not detect the BlackBerry smartphone when it is connected

Also, check that you are using only root USB ports...no hubs (sometimes the front-side ports are hubs...use a rear USB port). And make sure to try disabling USB power management in your system configuration (Device Manager).
Also check on conflicting software...it has been reported that the software package NTI Shadow&Ninja can cause a conflict; removing them and reinstalling the BB desktop software allows it to install correctly.
Apologies in advance if this is redundant -- there's no way to be sure if you've already seen and tried these. Also apologies if any are not presently available...RIM takes them up and down at will as they revise things.
Hopefully something there is helpful!
