1. run "rtl_tcp -a 0.0.0.0" on OpenBSD machine
2. run Airspy's SDRsharp on Windows machine
3. connect rtl_tcp server from SDRsharp client and start receive
4. change frequency on SDRsharp with up/down button (frequency number)

same problem will occur on CubicSDR with rtl-sdr (this occur
without rtl_tcp server).


It looks librtlsdr's radio controlling api like rtlsdr_set_center_freq()
is blocked during rtlsdr_read_sync() is activated.

(maybe libusb's control transfer is blocked whle bulk transfer is running)
