Took a long trip this past weekend, noticed that the XM station I am currently tuned to does not always update. About 50% of the time it will display the same artist/track label indefinitely, while all other stations seem to update. If I tune away from that station and then tune back in, it will update at least once and I will believe will continue to update indefinitely. I have an XMPCR with USB connection and listfollowssong=TRUE. Is this a known bug or most likely a problem with the XMPCR/USB -> serial driver?
