Cell phone Samsung Galaxy S3 I9300(SCHI535MBB) Carrier: Verizon Wireless. Can not share data (tether) w/ my laptop (Toshiba Satellite M645-S4070-Windows 7) via USB anymore. They stopped recognizing each other. I'm still able to charge it connecting to my laptop, but not share data (photos etc.). Any clue anyone? Thank you in advance.
