Establishing usbconnection without admin rights in linux and mac...

sreram.b

I had been trying to establish connection to my hid class device as a user in linux in vain.

I even tried using udev instead of libusb, giving MODE="0777" in udev rules determining the ATTRS{idVendor}, ATTRS{idProduct} and adding it as a separate rule file. Still I can run access usb device only if am an administrator.

Although I haven't tried this on Mac yet, feel will have the same problem there too.

Any inputs on how to give access to the normal user?

It is better that you use libusb mailing list for Linux
and Mac OS X related issues. Thanks.

Then it is rather a udev issue. Did you try to
detach the kernel driver inside your codes?

It is worse than you think in Mac OS X. You have to

You should try to use HIDAPI and not libusb
for cross-platform HID access.

Anyway, this thread is closed. Please use the libusb
mailing list for further help. Thanks.

It's likely you've forgotten to detach the kernel driver in the code.
