Some more info about this: I'm getting errors in my logs like this: Sequence Error!(hcd_frame=488669 ep=8in;wait=488668,frame=488668). Most propably some urb of usb-frame 488668 is still missing. Cause could be too long delays in usb-hcd interrupt handling. Looks like it might be a usb or irq issue and not really an alsa problem? In any case, switching USB ports seemed to fix it for a minute or so, but then it died again with the same error. I saw some web pages mentioning that this could be caused by CONFIG_USB_EHCI_SPLIT_ISO not being set in the kernel, but I do have that option set... any other ideas? -- Jon-o Addleman - http://www.redowl.ca ------------------------------------------------------------------------- Using Tomcat but need to do more?
