ftdi_transfer_data_done busy loop

[Omri Steiner <omri@xxxxxxxxxxxx>]

Hey,

It seems that both ftdi_transfer_data_done and ftdi_transfer_data_cancel call libusb_handle_events_timeout_completed with zero timeval, with the intention of indefinitely blocking (it even states so in ftdi_transfer_data_cancel's documentation).

However, in practice, libusb_handle_events_timeout_completed with zero timeval just acts as a non-blocking function, which means both of these functions actually busy-wait instead of polling indefinitely.

Am I missing something?

Shall I propose a patch?
