Q: How to cancel a transfer after device removal if libusb_cancel_transfer()
fails with LIBUSB_ERROR_NOT_FOUND since the device is removed?

A: The FreeBSD USB stack will automatically cancel all pending transfers
belonging to a USB device when it is detached and upon receiving a transfer
status of LIBUSB_TRANSFER_CANCELLED, pcscd should not try re-submit the USB
transfer and set its termination flag.
