Since the latest kernel updates in Cauldron - I am no longer able to see
my WAN modem again (Ericsson F5521gw)

The solution below doesn't work either . . . 

[root@ThinkFox rfox]# lsmod | grep cdc
cdc_ncm                18345  0 
usbnet                 36447  1 cdc_ncm
cdc_wdm                18885  0 
cdc_acm                28752  0 
usbcore               212051  9
btusb,uvcvideo,ehci_hcd,usbhid,usbnet,cdc_acm,cdc_ncm,cdc_wdm,xhci_hcd
[root@ThinkFox rfox]# mount -n -t usbfs -o
devmode=0664,devgid=43 /proc/bus/usb /proc/bus/usb
mount: mount point /proc/bus/usb does not exist

Looks like /proc/bus/ doesn't have usb anymore:
[root@ThinkFox rfox]# ls /proc/bus/
input/ pci/

Should I raise a bug?

Thx,
R.Fox
