I think all you have to do is this..... rpt.conf: (snip) [2532] ; Change this to your assigned node number rxchannel = SimpleUSB/usb ; Rx audio/signalling channel simpleusb.conf: (entire file) ; ; SimpleUSB configuration ; [general] [usb] eeprom=0 hdwtype=0 ; Leave this set to 0 for USB sound fobs modified using ; the instructions from usbfob.pdf.

Is there a stand alone document or page of info for chan_simpleusb?
I would like to try using it.
Is it the same as chan_usb but without carrier sense /PL decode? and DTMF decode?
And on a standard PC how do you build with this instead of chan_usbradio?
Thanks!
Steve
Other then the part about not being able to set levels in software, you are correct. With chan_simpleusb you definitely can set levels in software.
DTMF detection is definitely available with any channel driver.

Two questions:
(1) Do I understand that the main difference between chan_usbradio and chan_simpleusb is whether or not CTCSS encoding and decoding, squelch, pre-emphasis and soft limiting, de-emphasis, and audio level adjustments are available in software?
(2) Should DTMF digit detection be available with both chan_usbradio and chan_simpleusb?
If so, then it sounds like, assuming I have an RX radio that provides proper audio and does CTCSS detection and COR, then I should be all set with chan_simpleusb ... yes?
(Ooops, I guess that was really three questions.)
Thanks!

Yes, it works quite beautifuly with the URI, in fact it will support 2 of them *BUT* only with chan_simpleusb. The CPU does not have the horsepower to do the DSP routines used in chan_usbradio.
