This is the Linux driver for all the new Prism devices with an ISL38xx, even if they are SoftMAC. It supports USB and PCI.
For now, this is located at http://jbnote.free.fr/


This is the FreeBSD equivalent of islsm. It only supports USB devices, though.
Installation instructions are here, and are also included in the README file in the archive.
This driver reuses parts from the Linux islsm driver (a lot of the protocol reverse engineering comes from there).
This new version is for FreeBSD 6 only. FreeBSD 5 support has been discontinued.
p54u does NOT work with ANY Linux distribution.

You must use official 2.x ("SoftMAC") firmware with these drivers. Alternatively, both can also load unofficial reverse-engineered FreeMAC firmware, but the chipset has not yet been analyzed to the point where we can actually use the radio of the device, so FreeMAC is unusable for non-developers for now.
» Version for USB version 1 devices, using endpoints 0x02 and 0x82 (deprecated scheme)
» Version for USB version 1 devices
» Version for USB version 2 devices
» Version for PCI devices
