[linux-audio-user] Edirol UM-1S weird behaviour

[Christoph Eckert]

Hi,


I have problems using my Edirol UM-1S:

http://www.edirol.com/press/hirez_photos/um1_1s.html

When I boot while it is plugged in, it doesn't appear in 
kaconnect. Additionally, my DSL connection will not work.

When I plug it out and reboot, the DSL connection will still 
not work, I have to reboot again and then my box behaves 
correctly again.

When I boot and plug the UM-1S in after booting, the mouse 
will hang for some seconds. After that, the UM-1S will be 
ready to use in kaconnect in most (but unfortunately not all) 
cases.

When I do a tail -f /var/log/messages while pluggin it in, I 
get:

Nov 21 00:11:33 Grandevitesse usb 1-1: new full speed USB 
device using address 2
Nov 21 00:11:34 Grandevitesse snd-usb-audio: probe of 1-1:1.0 
failed with error -5

with error -5
Nov 21 00:11:34 Grandevitesse usbcore: registered new driver

A lsusb | grep -i Roland gives

Bus 001 Device 002: ID 0582:0009 Roland Corp.

When I do a

cat /lib/modules/2.6.7-gentoo-r6/modules.usbmap | grep 0009 | 
grep 0582

I get two lines starting with

snd-usb-audio
usb-midi

each.

So, the kernel seems to know the device. The question is, if 
really both of the modules are needed. AFAIK, snd-usb-audio 
contains both the usb and the midi driver. What is usb-midi 
for?

I'm currently using a Gentoo, 2.6.7-gentoo-r6 #5 SMP Sat Oct 9 
23:31:33 CEST 2004 i686 Intel(R) Pentium(R) 4 Mobile CPU 
1.60GHz GenuineIntel GNU/Linux.

The problem has been similar on my previous Mandrake box, but 
at least the DSL connection has not been affected. It also 
seems that not the DSL connection directly is affected but 
the network interface. pppoe tries to reconnect (I can see it 
in the syslog), but it can reconnect as soon as I do a

/etc/init.d/net.eth0 restart


Has anyone had similar problems, or does anyone use the UM-1S 
and has some tips? Why does my syslog give an

»probe of 1-1:1.0 failed with error -5«

?

Every wee small hint is highly welcome.


 Best regards
