Dear Sir/Madam,

I was a fedora user and managed to switch to CentOS.
Trouble I faced is that CentOS unable to form my Huawei 3G Broadband stick into 'ttyUSBX' format.
I need the ttyUSB format for my GSM modem purpose.
I tried in fedora 16 and I can read the ttyUSBX without any extra installation.

The output of dmesg after I insert my Huawei 3G Broadband modem:

usb 1-1.1: new high speed USB device using ehci_hcd and address 6
usb 1-1.1: New USB device found, idVendor=12d1, idProduct=1446
usb 1-1.1: New USB device strings: Mfr=3, Product=2, SerialNumber=0
usb 1-1.1: Product: HUAWEI Mobile
usb 1-1.1: Manufacturer: HUAWEI Technology
usb 1-1.1: configuration #1 chosen from 1 choice

usb-storage: device found at 6
usb-storage: waiting for device to settle before scanning
scsi11 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 6
usb-storage: waiting for device to settle before scanning
usb-storage: device scan complete

sd 11:0:0:0: Attached scsi generic sg4 type 0
sd 11:0:0:0: [sdc] Attached SCSI removable disk

Then I tried inserted the normal GSM MOdem I could read the ttyUSB0.

usb 1-1.1: new full speed USB device using ehci_hcd and address 9
usb 1-1.1: New USB device found, idVendor=067b, idProduct=2303
usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
usb 1-1.1: configuration #1 chosen from 1 choice
pl2303 1-1.1:1.0: pl2303 converter detected
usb 1-1.1: pl2303 converter now attached to ttyUSB0

What are the configurations I have to do in order to allow Cent OS create the ttyUSBX for my 3G broadband stick?
Your help is very appreciated!
