The Logitech drivers for my USB First Wheel mouse were OK. Similar to other post, Logitech was vague and unhelpful when asked for a response to technical problems. I also switched to USB Overdrive and am very happy with the product. It works better and with much more flexibility than the Mouseworks drivers. It would be great to see Logitech get on the bandwagon and start supporting the products they sell!!! At this point my next mouse will be from another vendor!!!
PS Mouse works great in both Q3 and UT with USB Overdrive. Never could get it to work with the Logitech drivers!
