I had a similar problem. I was attempting to transfer video from the HC30 to my Windows PC via the USB cable. Unfortunately, the software supplied with the device is not compatible with Vista. Since then, whenever I switch the mode to PlayEdit the screen displayed "USB MODE disconnect the USB cable before...".
I called Sony and they had me try several reset options without success. Then they said they I could send it in for a flat fee of $171.00 plus shipping to troubleshoot; parts would be extra. The camera is only worth 150 bucks.
My solution:
All devices that retain information such as date and time have a back-up battery, so I wen online and purchased a DCR- HC30 repair manual for 8 bucks. I found that the MS-200 board under the tape loading door hs just such a battery (although it is soldered in place and cannot be removed).
Following the dissambley instructions, I dismaltled the camcorder and disconnected the flexible board that links the MS-200 board to the main processing board, then reconnected it after 5 minutes.
I then reassembled the device and to my surprise, it functions normally now without displaying the USB error.
Here is a link to Tradebit, the site that sold me the repair manual:
