My usb spits out messages in stdout!!
 
My USB is really weird right now, everything works good except a problem with my souncard when I have my USB-webcam connected at startup. However, there are errormessages every 5-30 seconds or so when I switch to text-mode. Saing things like:
usb-uchi.c: interrupt, status 3 frame # (and a frame number)

I have an usb-cd-r and a webcam. What is causing these messages?? Why are they displayed brutally on the stdout?? Help me please!

Messages that are ALERT are usually displayed directly to console. Maybe the web cam and the other uSB devices are in IRQ conflict?
Just a guess....

I'm thinking that there's no resource conflicts as the usb controller uses 1 IRQ-the devices use the controller's IRQ.Could be a bios setting or the usb driver.What distribution and release ver of linux are you using?

I am using Redhat 7.3 (upgraded from 7.2). It doesn't matter if I have the webcam connected or not, messages still appear!! The messages didn't appear until I upgraded the system, but on the other hand the webcam wasn't installed until then (had to fix a couple of things with hotplug)
