My answer wont solve your USB connection problem, but as i read your request, it seems that you only want the files sent to your computer and that this is the main reason you made this question.
Since you are saying that you have lots of photos and videos on the phone, i assume that you can access these from your phone trough Android.
If i was you, i would skip the USB problem, and then connect to the computer via WiFi.
The most simple way to do this, i think is to connect to the WiFi network. Install Dropbox/Google drive or any other similar service on your computer. Install the app for the same service on your phone. And then go into your favorite photo browser/gallery and send the files over to the service and then you will have them automatically on your computer(if you have installed the applications).
This also gives you a backup of the photos and videos. (If you have had this backup today, you wouldn't have to worry about getting the files out from your phone) :)
Simple steps one by one, with my recommended service:
- Connect to WiFi with your cellphone
- If you dont have a Google account, make one here: Google Signup.
Most likely you have a google account, when you have an Android phone. Otherwise, you can not download apps through the Google Play.
- Install "Google Drive" on your computer. You can download it from the google drive download page.
- Install "Google Drive" on your phone. Download it from the Google Play store.
- Go into your favorite photo browser or gallery app on your phone. You can then select all files or only the ones you wanna transfer, and choose the "share"() button and choose "Google Drive". It will then use some time depending on the internet connection you have.
- You can then go on your computer and find the files inside the "Google Drive" folder.
Your files is now safely saved/backed up on three devices. Your computer, phone and "Google Drive".
I hope this solution works for you.
You can also make a permanent solution by downloading and using FolderSync wich will automatically upload photos to Google Drive when you take photos or videos.
