Hello, I have a question regarding a usb hub which is connected with a usb bluetooth adapter I setup asterisk16 with chan_mobile.Is working good. 1). When I use the bluetooth adapter into computer usb port is working voice 2 ways without delay : test OK 2). When I use the bluetooth adapter into usbhub (usbsplitter) which is connected to the usb port of computer the voice is one way : test FAILED Is some problem that the usbhubs don't support a2db or audio channels , only stick drive and printers? Do you have a solution for me? Thank in adavanced Sincerely Alex
