The attached screen dump clip0001 shows that Win7 is suggesting I have 8 USB ports free - there are in fact only 6 on the PC, and four are in use. It also says my USB attached drive (Seagate Freeagent Desktop 320Gb) can work faster, but testing with HD tune says the device works at 30MB/s which to me seems just as it always was, and much the same as it was on my previous XP pro PC. I just realised that I never installed any driver software on the Win 7 PC, so I have done that, with zero performance change of course. The second screen dump clip0002 is of device manager, telling me I have one USB2 enhanced port. My questions are: Have I actually got the device plugged into a USB 2 port, and if not how can I tell which is which?
