I suppose this is a Kernel:stable kernel?

Maybe Oliver has an idea?

There are two things you can do to help solve the problem.  The first is to use git bisect to find the kernel change which caused the error messages to start appearing.

The second is to capture some usbmon traces (see Documentation/usb/usbmon.rst in the kernel source).  Comparing a trace from the current kernel with a trace from an earlier kernel where the errors don't appear might provide some clues.

Hi Jansen,

Please enable the dynamic debug for USB to get more logs for easily get debug.

Please enter the below command and reconnect the device and share the logs.

echo "file drivers/usb/* +p" > /sys/kernel/debug/dynamic_debug/control

Thanks,
Sganes

Hi guys, sorry for silence: kbo bug mails were incorrectly routed by sieve here and ended up in some junk space :-( Fixed now.

@Jiri: yes, this is the stable branch from https://github.com/frispete/kernel-source.git, directly forked from https://github.com/openSUSE/kernel-source.git, with minor config changes added. I'm build stable and master branches in home:frispete:kernel{:HEAD}.

@Alan: I started with reverting 528222d853f92, which messes with rc timer durations.
While I cannot see any obvious flaws in the changeset (in the mceusb module at least), which doesn't mean *anything* of course, it might be a good start.

@Alan and @sganes: if that doesn't change the behavior, I will try to do the monitoring/tracing, as you suggested.

I've cc'ed Sean Young now, since he's in change of 528222d853f92.

Okay, reverting 528222d853f92 does the trick. 

My RC is working fine again for VDR, I can pull and plug the RC controller, VDR is complaining, but after restarting VDR, all is fine again. 

This is the kernel log of pulling and plugging the RC controller:

```

With 528222d853f92 applied, I wasn't able to recover at all, I had to stop VDR and pulling the RC controller in order to stop flooding the log with the urb status = -71 errors.

Sean, do you have any idea, what could have changed with 528222d853f92 resulting in this behavior?

I've been looking at commit 528222d853f92 for some time now and I can't see how this broke anything.

Can you please try again with mceusb dynamic debug enabled?

echo "file drivers/media/rc/mceusb.c +p" > /sys/kernel/debug/dynamic_debug/control

(Both with and without the patch please.)

The output should tell us what command is causing problem and what command changed (if anything) between the commits.

Thanks

Also could you post a picture of the mceusb device itself? Maybe I can track it down on ebay add it to my collection.

Thanks.

Sorry Sean, was distracted from day job(s) the last couple of days. 

I hereby promise to do my homework soon...

Device: Hewlett Packard TSGI-IR01

https://paste.opensuse.org/19971413

There are two similar models, this one is easily distinguished from the other by the cable attachment on the rear side, our's is asymmetric. 

Send me your post address and I'm happy to send you one! (I bought a bundle due to a couple of my friends operate similar VDR setups, based on my packages on OBS). While the device is somewhat chunky, it does support RC06 well, as being used by the most common Hauppauge IR remote, that we all accumulated over time:
