Hello, Still having trouble with my DMk URIx dongle. I have installed "uridiag" a standalone program to test a known good unit having returned it to DMK. They were very gracious and tested it for me and found no problems with it. The loop around has been tested for continuity a number of times and tested good each and every time. I appears that I have a driver problem based on the "Unable to" error that is displayed upon opening the program although it finds the URIx. Some of the test appear to work however the "T" test does not nor does it see audio in from the radio however; audio out to the radio is ok. Any help would be appreciated. root@JamestownNY:/usr/bin# lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 003: ID 0d8c:013a C-Media Electronics, Inc.
