Hello: I have used Suse for many years at home and have just upgraded to SuSE 9.1 in anticipation of upgrading all of our servers at work to the Corporate version of 9.1 or new 9.2 to take advantage of the 2.6 kernel. My family and I watch all our Television on the Computer and have successfully used our Nova-T (TTUSB) device for over a couple of years now in Suse pre 9.1 using the dvb-kernel drivers on a 2.4 kernel. Since upgrading to Suse 9.1 however, I have had many problems. 1. The kernel that comes with the distro (download) the built in DVB drivers, dvb_ttusb_budget and alps_tdmb7, did not work .. or at least the frontend alps_tdmb7 did not work. 2. After updating the kernel to 2.6.5 -7.111 the built in drivers did work and I was able to TZAP to the channels .. however I was not able to watch the DVB stream in xine or mplayer. 3. The reason for this was an error in dmesg: ttusb_start_iso_xfer: failed urb submission (0: err = -22)! 4. I wrote a posting on the linuxdvb site and downloaded and installed the dvb-kernel CVS drivers which had fixed this issue for some people, adding the line urb->interval = 1; after urb->transfer_flags = URB_ISO_ASAP; in the ttusb_start_iso_xfer function. 5. However, this did not fix the issue. I still get the failed urb submission error. 6. I just received an e-mail from one of the developers of the dvb-kernel drivers that :
you don't really have a choice and need to start to debug the USB host driver. Try to find out at which point in the kernel USB
7. However, I am not sure how to do this... and also since the technotrend / hauppauge ttusb is the most popular DVB-T device, I figured someone must have had this problem in SuSE 9.1 thus far and thought I would write you. 8. The only other pecularlity I can think of is that I am also using an analogue tv card wintv card .. and when I first loaded the 2.6.5-7.111 kernel it tried to load the dvb_bt8** frontend driver which messed up my analogue reception. I had to change the dvb file in init.d to only load the alps_tdmb7 frontend which I have always used successfully and is the right one for my ttusb device. 9. If we can't get this to work .. how difficult is it to go back to a 2.4 * kernel in Suse 9.1 .. as I wold hate to have to go through all this work and then go back to a previous distro. And also the whole point of this was to test 9.1 before introducing it at work. Thanks for your help. David ___________________________________________________________ALL-NEW Yahoo!
