In short, looks like a quick and wrong fix to me.
The right thing to do would be to find out why libusb on sun rays does
not provide the extra buffer as compared to libusb shipped with normal
modern linux distros. Which version do they have? The latest libusb
definitely does something like below, why do it again when walking
through the list of devices later?
int usb_find_devices(void)
{
...
udev = usb_open(dev);
if (udev) {
usb_fetch_and_parse_descriptors(udev); -> that's where the
extra buffers are allocated
usb_close(udev);
}
}
