I have a USB2 7-in-1 card reader but only USB 1.1 - it works fine.
Here's a description of USB2's abilities:
"USB 1.0/1.1 support data transfer at up to 1.5 Mbps for low-speed devices and up to 12 Mbps for full-speed devices. Microsoft, HP, Compaq, Intel, Agere, NEC and Philips are seven core members of USB-IF to have worked on USB 2.0 standardization. USB 2.0 will support up to 480 Mbps for high-speed devices.
"USB 2.0 is suitable for high-performance devices such as high-quality video conferencing cameras, high-resolution scanners, and high-density storage devices. In addition,
"USB 2.0 supports old USB 1.0/1.1 software and peripherals, offering impressive and even better compatibility for users."
Big Elf---yes the drivers were loaded; an easy enough thing to forget.
St Lucia and Stuartli---In my experience they are backward compatable! I know because for some unknown reason the darn thing is now working, it seems that time and Freecell sorts problems out..I have also loaded it on to a Packard Bell machine and that was successful too.
Thanks for your assistance and interest..Regards Ratler.
