Can I use your #13865 IDE 2.5 Hard Drive USB connector with my laptop that has USB 1.1? I know that's slow - I just need to get some data off my replaced laptop drive and then send it back to Dell.

Yes, USB 2.0 is preferred since you can move data faster, but USB 1.1 is fine. Your transfer rate is about 1 megabyte per second (max), so if you have 100 MB - it will take about 100 seconds (1 minute, 40 second).
