Hi All,
I've just brought a new laptop , Lenovo Thinkpad Edge 13".
I am trying to get my Roland Edirol UA-25ex to work as a capture device under jack.
I've used this USB sound card quite a lot under linux and never had issues until now.
Everytime I go to set it up in duplex mode 48khz it throws the flowing errors :-
Jack :-
Sat Jan 29 10:35:28 2011: [1m[31mERROR: ALSA: could not start playback (Broken pipe)[0m
Sat Jan 29 10:35:28 2011: [1m[31mERROR: Cannot start driver[0m
Sat Jan 29 10:35:28 2011: [1m[31mERROR: JackServer::Start() failed with -1[0m
dmesg :-
[ 384.261578] ehci_hcd 0000:00:1d.0: iso resched full ffff880136759000 (now 6272 max 14464)
[ 384.261588] cannot submit datapipe for urb 0, error -28: not enough bandwidth
I think its from a buggy usb hub in my laptop
