I have a pavilion desktop computer and wish to connect it to my droid cellphone in order to retrieve photos on my phone. When I try to connect phone to computer the computer shuts off my phone. This cable and usb work fine in the Verizon retail store, freely and offertlessy transporting photos but not on my hp. Cell phone salesman says there is a security block of some short and he cannot help me. Hp says that cell phones are not their responsibility but for a small fee that will try to help me.
