2018-11-09 NIIBE Yutaka <gniibe@fsij.org>
* src/usb-ccid.c (wait_for_tx_finish): New.
(ccid_error, ccid_power_on, ccid_send_status, ccid_power_off)
(ccid_send_data_block_internal, ccid_send_data_block_0x9000)
(ccid_send_data_block_gr, ccid_send_params): Add call of
wait_for_tx_finish.
(ccid_handle_data): Move c->state change before
ccid_send_datablock_gr, because of wait_for_tx_finish.
(ccid_thread): Don't handle EV_TX_FINISHED.
2018-11-09 NIIBE Yutaka <gniibe@fsij.org>
* src/usb-ccid.c (ccid_handle_data): Set c->state for pinpad input.
