Hi All, Although not srtictly an issue with X10 but I thought it may help someone (took me 3 days to find a resolve). I updated to 2.1 using SE PC suite, all good on the handset and a lot smoother. However, PC suite hijacked all of my USB's on my laptop, they wouldn't recognise anything plugged in, not even the handset!. It had installed a driver called "seehcri" which I could not get rid of, even uninstalled PC suite etc, still no joy. Then I came across the following VMware Communities: usb controller initialization failed -... which resolved and restored my drivers, I now no longer use anything SE. Hope it helps someone.
