When UMIK connected directly to computer everything goes fine. When UMIK is connected via USB hub, even though REW recognizes UMIK-1, it can not access it. Please see attached.

Exact error text is:

REW V5.20.7 running Oracle Corporation JRE 1.8.0_251 32-bit on Windows 7 Locale: language en, keyboard US, windows-1252 at 120 DPI

Message:
javax.sound.sampled.LineUnavailableException: Microphone (Umik-1 Gain: 18dB does not have any lines supporting PCM_SIGNED 48000.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian
------------------

Same applies to the output when connected via USB hub. Output settings set to "default". It checks level thru the amp when connected directly to it. WinAmp also goes to amp. When connected via USB hub, REW output is directed to internal computer speakers even though WinAmp continues to play via amp.

Please advise
Many thanks

Assistance with REW should be posted in the REW forum. I will move your thread there. :T

On the output side, if you leave the settings as default the output will go to whatever device Windows has set as the default, which changes as devices are connected and disconnected.

For the UMIK check that another application hasn't grabbed it exclusively, the message amounts to REW asking for data from the mic but the OS saying no. Also start REW after you make your audio device connections and avoid disconnecting while REW is running, Java is quite slow to pick up changes in the available devices.
