If you do have a driver already driving your device, and you need to
remove that driver, you can use a UsbInterfacePolicy while claiming the
UsbInterface, and make the "forceClaim" method in the policy return true.

Hello,
Do you mean that your devices are RS232 or USB? If you want to
communicate with USB devices, you should use javax.usb, however if you
want to talk to RS232 devices, you should use javax.comm. Since you say
your devices are RS232, I think you probably want to use javax.comm.
If your d
Hello all,
I wasn't running the code as root (I must admit it was quite
obvious) now I can see the devices.
Thank you very much for your help!
Best regards,

You need /proc/bus/usb/ mounted (the usbfs filesystem) and you need
read-write access to the device nodes (/proc/bus/usb/NNN/NNN). By default
the nodes are read-write only be root. On 2.4 kernels you can make them
read-write by mounting the filesystem with the mount option "devmode",

Hello,
We are working in a project at about three years, we've always used
RS-232 and the javax.comm API to connect several apparatus to different
computers, but now we've decided to use USB to control the new apparatus.
Since we use Linux and Java, I've decided to use your API, but when I
