Hi,
The GPIB-USB-B will definitely not work on a system with a 2.4 kernel, as the USB host controller support in 2.4 was not sufficient for our needs. If you look in the README, the GPIB-USB-B is officially supported on Mandrakelinux 10.0 and SUSE LINUX Professional 9.1. The device may work on a Debian system with a 2.6 kernel, but there is no official support for Debian.
