RE: [PARTIALLY SOLVED] Can't use my Pinnacle PCTV HD Pro stick - what am I doing wrong?




Hello!  In a last ditch effort, I decided to try downloading a v4l driver snapshot from February back when I had my Pinnacle HD Pro Stick device working.  To my amazement, the old drivers worked!

By process of elimination (trying newer and newer drivers until my Pinnacle device was once again not recognized), it appears that changeset 11331 (http://linuxtv.org/hg/v4l-dvb/rev/00525b115901), from Mar. 31 2009, is the first one that causes my device to not be recognized.  This is the changeset that updated the em28xx driver from 0.1.1 to 0.1.2.  Here, again, is the dmesg output from a newer driver that does NOT work (this one from a driver set one day later, on Apr. 1, 2009):

Notice that the tvp5150 device is being recognized and the firmware from /lib/firmware/xc3028-v27.fw is being loaded.

If need be, I guess I can continue to use this changeset, the last known revision of the em28xx drivers that work with my card.  But I thought I'd mention my discovery, in case someone more clever than I can discover what happened that caused the problem.  (Devin, I know you mentioned that you have the same Pinnacle device that I have, and yet yours still works even under the most recent drivers.  Could we have slightly different devices, with mine containing some "feature" that has caused it to stop functioning with the latest em28xx drivers?)

Again, thanks to everyone who helped.  If this should go in a bug report, I will happy to do so if someone indicates that.

(This is the "lsusb" info for my device, in case it needs to be more clearly identified):
