The same problem seems to be valid for the Haupauge Nova-TD (a dual receiver). After a few minutes the ehci_hcd core is halted. Have you got any ideas how to solve this? I've read setting URB to 1 (?) should solve this issue - but where to set this parameter and did it work out? There's a patch on the linux-media list. Search for a thread with dib0700 Nova-TD-Stick problem as subject. disable_rc_polling does not solve the problem. At least at my Ubuntu Server 8.10 with kernel 2.6.27-7. Seems to be different problem than. At least kernel 2.6.27.x works here without problems.

Haupauge Nova-T 500 2.6.28 regression dib0700
Hi, I have some difficulties with the Hauppauge Nova-T 500 and 2.6.28 kernels. Following USB errors appear with 2.6.28.4 every 100ms: Feb 15 02:46:03 golem [ 7720.876132] usb 2-1: events/3 timed out on ep1in len=0/6 Feb 15 02:46:03 golem [ 7720.976039] usb 2-1: events/3 timed out on ep1in len=0/6 Feb 15 02:46:03 golem [ 7721.076068] usb 2-1: events/3 timed out on ep1in len=0/6 The device is still useable but occasionally I see the same error with additional usb errors (iirc same kernel and config) Feb 17 20:33:17 golem [ 14.733031] ehci_hcd :01:06.2: reused qh 8800bf80d140 schedule Feb 17 20:33:17 golem [ 14.733040] usb 2-1: link qh64-0001/8800bf80d140 start 63 [2/0 us] Feb 17 20:33:17 golem [ 14.783035] usb 2-1: unlink qh64-0001/8800bf80d140 start 63 [2/0 us] Feb 17 20:33:17 golem [ 14.783107] usb 2-1: events/3 timed out on ep1in len=0/6 ...

We actually rely on the bulk endpoint timing out to query the IR port if there is no keypress. I wonder if they introduced a new kernel warning in 2.6.28.4 when this occurs. Regarding the other issue, is there any correlation with the errors to plugging/unplugging the devices? Perhaps there is an issue with cancellation of the thread that does the polling when the device is disconnected. I actually don't have a Nova-T 500. I did all the development on the dib0700 based Pinnacle 801e. Devin -- Devin J.
