This project provides a Free Software (and Open Source) Java API for USB, supporting applications using Java host-side software to drive USB devices. Right now it's of most interest to developers, but some basic tools (including jPhoto) have been developed. Read the API FAQ (and other links at left) for more information.
Although the bulk of this code works on any Java platform, access to USB devices currently requires that they be connected to a GNU/Linux host system. Your clients can be on other systems, if you like. The USB Host implementation works on most recent GNU/Linux distributions, either with the Linux 2.4 kernel support, or a backport of that into 2.2.18 kernel (and later). Of course, the 2.5 kernel works too. As one data point, the RedHat 7 distribution has worked without needing any patches or other upgrades.
News, 17 September 2003 OK, well the jUSB RPMs still aren't updated -- shoot me! But for all of you wanting jUSB/Windows support, there's software (source + binaries) available from Mike Stahl. (The content here isn't yet updated to use that code.)
News, 3 April 2003 We should be getting some updates soon, like an RH 9 RPM. Meanwhile, take a look at jSyncManager, an application using jUSB to synchronize with Palm PDAs.

Two interesting CVS updates.
Win2K/XP starts; first code from Wayne Westerman (of Fingerworks).
News, 22 March 2002 Nothing much new to report, except that after a year or so the 2.4.19 prepatches (and 2.5.7 of course :) have the EHCI driver needed to support USB 2.0 device access. And yes, USB 2.0 devices are finally happening!
News, 14 February 2001 New 0.4.4 release from CVS, including initial USB 2.0 support.
News, 3 January 2001 CVS has some bugfixes to the RMI support, and also fixes some bugs in accessing interface descriptors.
