Libinklevel is a library to check the ink level of ink jet printers connected via USB. Canon BJNP network printers are supported too. It works on Linux and FreeBSD.
CUPS back-end for the canon printers using the proprietary USB over IP BJNP protocol. This back-end allows Cups to print over the network to a Canon printer. The design is based on reverse engineering of the protocol.
Version 2.0 adds ink-level reporting and improved out-of-paper detection.
Version 2.0.1 is now released under GPLv2 or later to be compatible with the changed cups license.
Open Source Linux driver for wireless network cards (DWL-[G]520+ PCI, DWL-[G]650+ CardBus, GL-2422MP mini-PCI, DWL-120+ USB etc.) which use the entirely undocumented Texas Instruments (TI) ACX100/ACX111 chips, for 2.4.x , 2.6.x to 3.x kernels. FreeBSD: see some other website (FIXME URL got clipped).
!! BIG FAT NOTE: development (i.e., driver "releases") is happening in git source repository tree (as of 2011-09-04), thus you're expected to look there (see web site menu Code --> Git) !!
hardware log monitor that will display log behaviour via various hardware (parallel port, USB devices, ...). You can specify pattern(regexp) in log(s) on which hardware will turn on. It has also some unique ways of visualization of log files.
