hi,all
I have ported the libusb &  hidapi  to the android,

but when I use  ndk-build to operate the usb device on java platform,I
always return false.

so I do "chmod 666 /proc/bus/usb/002/001" cmd manually to make the device
can be read & write ,  then it return OK.

but I think when I mount the usbfs,I have made the  usb  can be read & write
already by the cmd "mount usbfs none /proc/bus/usb -o devmode=0666".


why?
