Usb1 audio device on usb2 hub doesn't work. #315

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Usb1 cmedia dongle causing the following error:
"kernel: cannot submit datapipe for urb 0, err = -38"
After doing a google search for the issue I found this site with a possible 
solution.
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/28840
see posts #21 and #23
# CONFIG_USB_EHCI_SPLIT_ISO is not set.
I can confirm that using the dongle directly it works fine with the mpd and 
extramodules packages..
Would it be possible to compile the kernel with this enabled ?

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

It's worth a try. I hope that doesn't break anything.

Hi stefansc. I dont mind being a guinea pig to test this :) as I,ve just 
ordered a new device from delextreme its the NS-K330 with 2 usb ports which 
should solve my problem anyway? But it would be nice to try and see if it 
works. I'll take full resposibility for breaking it ;) 
regards jellytot.

Try the attached image then. 

It seems to be safe to enable the option because most devices don't use iso 
transfers anyway (the only one I could find was an USB speaker). I was mostly 
worried that it could affect disk support.

Hi stefansc. Just to confirm that your new image appears to be working ok! no 
noticeable problems so far :) A big thank-you for fixing this.

It looks like I jumped the gun a bit too early :( I dont know what went wrong 
but
when I tried to disconnect/ reconnect the drive and hub, the sound stopped 
working..
now I get this error:  File exists insmod: can't insert 
'kernel/sound/core/snd-page-alloc.ko' .I've been trying to get it to were it 
worked like the first time to no avail? I'll just wait for the NS-K330 to 
arrive...regards Martin

If I remove the USB speaker while MPD is playing the port seems to get knocked 
out. I have to reboot to get it to work again.

Is that what you are seeing?

After frantically trying different things, reinstalling and removing packages 
it seems to be working again. It works ok at the moment even when I restart the 
unit, so I'm
reluctant to upset it again :) not sure if loading the packages in any order 
effects the operation ? I think I tried and still had the issue, my problem was 
that I couldn't get mpd to run at all, and then after trial and error it 
started to work! 
regards Martin
