Hi guys,

sorry to break threading but I wasn't subscribed to the mailing list.

libusb not being able to unbind HID driver for Huey is not a security
problem : I have the problem even as root.

After a quick review of usbio.c code, it appear unbinding is tried
only AFTER usb_set_configuration success. Unfortunately,
when device is handled by usbhid, ioctl IOCTL_USB_DISCONNECT fails,
preventing unbind.

I've also taken the opportunity to check your changes on libusb,
compared to "upstream". Only one change seems relevant for linux. Do
you have
more informations on it ?
