[Asterisk-Users] S100U / wcusb Zaptel driver / Crash / Kernel problem maybe?

[Derek Conniffe]

Hi Everyone,

I've been using Asterisk now for a few months for my small office (which 
is mostly just me while other guys are always on the road so we rely 
heavily on telephones) - I'm very excited with Asterisk as it can do 
everything I've ever wanted to do with a PBX.

I'm having a problem with an S100U USB --> Telephone interface.  I 
haven't actually made it work yet but I would like to hang a coreless 
telephone off this interface if possible.

The problem is that when I connect the S100U and then load the wcusb 
driver (with "modprobe wcusb") my linux server will hang a few seconds 
later - no messages at all on the console or log files.  I need to power 
down and up the server to get it back running again.  If I dont run the 
"modprobe wcusb" command the server is fine (of course without the S100U 
interface active).  I dont have any other USB devices connected to this 
server.

My current server configuration is: -
    Pentium III 550Mhz (An old gateway mini tower)
    SuSE 9.1 with a newer Linux 2.6.7 kernel from kernel.org
    SCSI disks with a adaptec 2940 controller
    AVM Fritz ISDN card (with fcpci / capi / chan_capi) for my ISDN line 
into Asterisk
    X100P (104P?) for an analogue POTS line into Asterisk
    And the problem S100U USB dongle I/F

I'm a bit confused by USB on Linux (when it works I never think about 
it!).  DMESG reports the following about USB when the server starts up: -
usbcore: registered new driver usbfs
usbcore: registered new driver hub
USB Universal Host Controller Interface driver v2.2
PCI: Found IRQ 9 for device 0000:00:07.2
PCI: Sharing IRQ 9 with 0000:00:10.0
uhci_hcd 0000:00:07.2: UHCI Host Controller
uhci_hcd 0000:00:07.2: irq 9, io base 00001c40
uhci_hcd 0000:00:07.2: new USB bus registered, assigned bus number 1
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 2 ports detected
usb 1-2: new full speed USB device using address 2                     
                <<<< I guess this is the S100U ?


I dont know if the PCI IRQ 9 stuff is anything to do with USB (I guess 
not?) - but those two lines appear just like that in the middle of the 
USB stuff.

I always load the modules I need for Asterisk in the following order:
    modprobe fcpci
    modprobe capi
    modprobe zaptel
    modprobe wcfxo

In all other respects Asterisk works 100% perfectly for me

Thanks very much,

Derek Conniffe
