USB connection problems on Z1 with WIndows 7 Sony VAIO

[HucsJe]

I have problem with USB (MTP) connection between phone and PC Companion.

The Phone is not detected at all when connected using USB cable.

I have tried the suggestions in the FAQ and some of the points given in this forum.

Restart PC, phone, reinstall PC companion, check for updates, use different USB ports, cables tested PC USB ports.

What else?

Could anyone help? Thanks in advance

what shall I do with the file??

Save the file somewhere that you will remember. Open Device Manager by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then, under System, clicking Device Manager. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.‌

In the list of hardware categories, find the device that you want to update, and then double-click the device name.

Click the Driver tab, click Update Driver, and then follow the instructions. You will be prompted at one point through the manual installation to point to the driver at which stage you direct it to the file you have downloaded.
