I’m using Acer Aspire 5050 laptop (I know… I know it’s waaay to old) with Ubuntu 10.04 LTS Lucid Lynx

This modem has built it CD-Rom support — zerocd feature. On Windows, it’ll be auto-mounted once the modem plugged in. On Ubuntu, it’s a different story.

On Ubuntu, there is no new drive — nothing mounted.

Here is dmesg -c output:

root@laptop: /home/me# dmesg -c
[ 189.336303] usb 1-2.6: new full speed USB device using ehci_hcd and address 11

nothing related after waiting for device to settle before scanning, it’s stuck there.

and here is lsusb output:

Bus 001 Device 011: ID 05c6:1000 Qualcomm, Inc. is the modem on usb-storage mode.

So, the modem Vendor ID (vid) is 05c6 and Product ID (pid) is 1000

The built-in CD-Rom only contains software and driver for Windows boxes, thus, not needed here. We need the usb-storage mode kicked out so the modem mode can be kicked in. In short, the modem mode will active once the usb-storage mode deactivated.

How?
Of course by ejecting (or unmounting) the CD-Rom drive. Here’s come the trouble. There is no sign of any device created in /dev/. How can we ejecting something that does not exist?

We need help from usb_modeswitch.

If you want to compile it manually, download it here.
Do not forget to download usb-modeswitch-data aside of usb-modeswitch.

Ubuntu packages:
Find on universe usb-modeswitch_1.1.0-2_i386.deb and usb-modeswitch-data_20100127-1_all.deb, download and install them.

usb_modeswitch requires the following configuration:

########################################################
# Venus Fast2 (white)

DefaultVendor = [vendor ID to look for (mandatory -- storage mode)]
DefaultProduct = [product ID to look for (mandatory) -- storage mode]

TargetVendor = [target vendor (optional, for success check) — modem mode]
TargetProduct = [target model (optional, for success check) — modem mode]

CheckSuccess = [check switching result after NUM secs]




MessageContent= [command to send (hex number as string)]
MessageEndpoint= [where to direct the message (optional)]
########################################################


The unknown values are TargetVendor, TargetProduct, MessageContent & MessageEndpoint.

TargetVendor & TargetProduct is Vendor ID & Product ID after switched into modem mode. If you have a Windows boxes, you can see them in Device Manager, which are: 19f5 & 9909 respectively.

As for MessageContent & MessageEndpoint, we need to do USB sniffing to get those. I got them after a painful searching on the sniffer log. Let me help you by providing them here:
MessageContent : 55534243105c838a000000000000061e000000010000000000000000000000
MessageEndpoint : 0x09

Create a new file on /etc/usb_modeswitch_venust_fast.conf:

nano /etc/usb_modeswitch_venust_fast.conf


and fill in the details:

########################################################
# Venus Fast2 (white)

DefaultVendor = 0x05c6
DefaultProduct = 0x05c6

TargetVendor = 0x19f5
TargetProduct = 0x9909

CheckSuccess = 20




MessageContent= "55534243105c838a000000000000061e000000010000000000000000000000"
MessageEndpoint= 0x09

Run it:

root@laptop: /home/me# usb_modeswitch -c /etc/usb_modeswitch_venust_fast.conf

Check lsusb, you’ll see something like:

Now it’s on modem mode (the bold line)

Simply use wvdialconf to auto configurate it with wvdial. All you need to do is fill in the blanks, ie: Phone, Username and Password. On AHA, its #777, aha.co.id and aha, respectively.

Good luck!
