HP hp3110 HSPA+ Mobile Broadband Module Modem is not shown up

[Harald Jung <jung ecos de>]

Hi,

we were in touch with a HP notebook which is shipped with a broadband 
device.
The device should be a "HP hp3110 HSPA+ Mobile Broadband Module Modem" 
which isn't visible on the usb bus nor the pci bus.
Booted up with windows the device is visible and working.
Have you ever heard about a problem like this?

Harald
