[linux-audio-user] Edirol UA-25 and my USB hub

[Adrian Prantl]

Hi fellow LAU'ers,

I'm expieriencing strange things with my new Edirol UA-25. I am running Debian 
SID with a vanilla 2.6.10 kernel. The device works really fine (it has his 
own USB controller and is directly connected to the board) when I try to 
playback _or_ record @ 24Bit/48khz. 
But as soon as I try to do both things simultaneously (using arecord and 
aplay) - after about 2 seconds - I get this:

Jan  9 15:06:23 vicviper kernel: hub 2-0:1.0: port 1 disabled by hub (EMI?), 
re-
enabling...
Jan  9 15:06:23 vicviper kernel: usb 2-1: USB disconnect, address 3
Jan  9 15:06:23 vicviper kernel: cannot submit datapipe for urb 0, err = -19
Jan  9 15:06:23 vicviper kernel: usb 2-1: new full speed USB device using 
uhci_h
cd and address 4
Jan  9 15:06:26 vicviper usb.agent[5253]:      snd-usb-audio: already loaded

to make sure it isn't a hardware issue, I tested the device with Audacity in 
Windows on the same machine, and that worked just fine.

Sooo. Does anyone have any idea what I could try to fix this problem? It sure 
does render Ardour unusable for me, which is - well - bad.

thanks alot,
Adrian
