Subject: Don't close/reset the FTDI device too often.
X-Git-Tag: libsigrok-0.1.0~287
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=15f2d0c0f2e39bc4338b0781b581aced0fca8e0c;p=libsigrok.git

Don't close/reset the FTDI device too often.

Only call la8_close_usb_reset_sequencer() in hw_closedev(), it's not
needed in hw_stop_acquisition().

Thanks Ken Mobley of ChronoVu for the report.
