Sony Ericsson K750i & USB Cable Problem

A forced restart is needed after disconnecting USB cable between phone & computer. Read more…


I just purchased an unlocked Sony Ericsson K750i phone to use with T-Mobile. Love the phone, and was able to get my contacts into it via Bluetooth and iSync. Among its many great features is also a 2MP camera, which takes very nice photos (has a flash). However, I noticed a problems when connecting the USB cable to download them to my 1st generation 17? Powerbook (it has only USB 1.1) under OS10.4.2, which I?ve reported to Apple:
When I 1st connected the phone, I did not have photos on its memory card, and after unplugging, I received the screen to force a restart. Today, I had 4 photos in the phone?s memory when I plugged it in. As before, iPhoto started up automatically; this time it asked if I wanted to download the photos, just as with my digital camera. All 4 photos downloaded without incident. While I kept the memory card mounted, I was able to start programs without incident. I then unmounted the memory card, but left the USB plug connected. I could start programs without incident. It was only after I unplugged the USB cable that, after about 6 seconds, the ?you have to restart your computer, so please hold down the power button or press the restart button? message in several languages came up.
Here?s the report message I received after the forced restart:

Thought I should warn folks, unless I?m the only one having this problem. Very happy with the phone, which also has much better reception than my old T68i.
