Hi Guys: I am preparing a RPi3 to replace a dying PC with ACID at my repeater site. The Pi will control 2 full-duplex repeaters. I have prepared the config files at home and plugged in 2 (modified) USB fobs. Both fobs worked initially... i.e., I was able to connect a test repeater to each fob and hear telem' data out of the repeater / corresponding to the applicable node #. I am using usbradio for both fobs (config changed in modules.conf and rpt.conf) The issue I have is that the LED on one of the fobs is no longer flashing and hence, no audio out of that fob. The LED is however, on permanently. Here is the output of 'lsusb': Bus 001 Device 005: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller Bus 001 Device 004: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter It is the 2nd fob that seems to be non-responsive. Any ideas folks? I am reluctant to swap fobs between USB ports as I know that usb enumeration can be a pig! Cheers, Ramesh, VA3UV
