Do you mean the libusb_pollfd entries?
They are:
{fd = 0x7, events = 0x1}
{fd = 0xc, events = 0x45}
I translate these into select(2) params like this:
nfds = 0xc, readfds = {__fds_bits = {0x1080, 0x0 <repeats 31 times>}},
writefds = {__fds_bits = {0x1000, 0x0 <repeats 31 times>}}, exceptfds = {
__fds_bits = {0x0 <repeats 32 times>}},
And call select with timeout = NULL (since libusb_get_next_timeout returned 0)
