If you don't have a recent kernel, I have a TEMPORARY solution. I have exactly the same problem and solve it by calling the "rmmod hid" command within the java program (using the Runtime and Process classes). In my case, the HID driver isn't used by any other module. In yours, you should maybe call "rmmod" on all modules that have called the HID driver before you can remove it. It allows not to modify the hid_core.c file but I insist that it is NOT a very elegant solution (moreover, it requires to be connected as root). PS : at the end of the java code, the "insmod" command is called to retrieve a well-functionning linux system. Aurelien -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] la part de Aaron Metzger Envoye : vendredi 10 octobre 2003 23:17 A : [EMAIL PROTECTED] Objet : [javax-usb-devel] HID usage under Linux This is a usability question in a Linux environment more than it is an API question. My experience is that I can't "claim" any device with javax-usb that has already been claimed by the Linux kernel drivers. Unfortunately, the Linux HID driver claims a lot of devices including the one that I would like to control from Java. Does anyone have any advice as to how to forcefully claim a device from Java or how to prevent the Linux HID driver from claiming one particular HID device out of the many attached to my system? I'm ready to start hacking hid-core.c unless someone has a more elegant solution. Thanks in advance for any info. -- Aaron ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
