    Tried latest SE PC Suite (4.0) but still no luck. Vista simply installs Unknown device drivers. When forcing provided Z550 drivers, it says either drivers cannot start (code 10) or drivers probably were written to other version of windows.

MY Sony Ericsson Z550i and file transfer option

you need to get your phone checked at a sony service center or a third party repair shop(use only if out of warranty).
either your Ribbon inside the folding hinge is broken.
or you have something shorting the PCB inside the phone.

do not attempt to open it on own, you won't be able to fix it.
just my 2 cents.

I can't transfer files to upload pictures to my pc using usb cable

Go to Sony site and download the driver for your phone
Step 1
Remove data cable from usb and put it into a different one
Step 2
Connect your phone to the computer with the cable and turn it on.
You might see "Found New Hardware" wizard. DON'T let Windows search for the driver; point it to the driver you just downloaded, and install the drive on your computer.
After the driver as installed you should be working 100%

Unrecognized USB device

Check whether the software CD you received with the camera, support the Win XP OS. In case it doesn't, go to the Canon web site and download the relevant drivers for you camera and OS. Good luck!
