On my OLD laptop, which only has WIN98SE and only one USB1 port, installing a specific device driver for one item seems to have uninstalled a different item, and I can't get it back.

The memory sticks are just memory, not camera cards (SANDISK units), and are USB2. They work fine for what I want, backup and data transfer, provided the system finds them!

Also, when I tried using a minihub, my USB DVD drive hijacked it, and nothing else would work when it was plugged in. This sort of defeated the object a bit, because I wanted to use a USB network adaptor at the same time, to get data off the DVD onto the network.
