(This post is the 3rd part of my Ubuntu Linux Router Upgrade Project.)
Note that all Linux commands here assume use of Linux 8.04 (""), with all updates installed as of 2008-09-30.
The device I purchased for 's service ( ) was a UM175, purchased for $100 before a $100 mail-in rebate on a 2-year contract.
Some specs as printed on the box and from Alltel's website:
- USB modem with swivel connector
- Compatible with Windows XP, Vista, Mac OS X
- 1xRTT/EVDO Rev 0 and Rev A Ready
- CDMA 800/1900MHz
Also Known As
The "Alltel Part#" listed on the box label is "UM175ALA". The P/N on the device label is "UM175AL". (I'm assuming the "AL"/"ALA" suffixes are specific to Alltel?) The FCC ID is PP4PX-700. Also listed on the device label: "Distributed by UTStarcom Personal Communications. Made in Korea by PANTECH. QUALCOMM 3G CDMA."
When connected to Windows before installing the drivers, the following "Hardware Ids" are listed in Device Manager where it is recognized as a "USB Mass Storage Device", with a vendor ID of 0x106c and a product ID of 0x3b03:
USB\Vid_106c&Pid_3b03&Rev_0100
USB\Vid_106c&Pid_3b03

Should be Easy (or not)
Even before I made the purchase, I ran across a blog post by Jason Costomiris, "". Reading it gave me a good vote of confidence that my plan should work. He had success using the "same" device under the same distribution of Linux that I was planning on. Verizon and Alltel use the same technology (and ). The instructions made it almost appear as simple as "plug & play".
Unfortunately, this is where things got tricky. The device is not even shipped with drivers, at least not on a CD. Instead, the device doubles as a USB mass storage device (USB MCS / UMS), and is recognized as an -enabled CD-Rom with drivers for Windows and Mac OS. Under Windows, after the drivers are installed, the device is listed as a "PANTECH UM175AL Composite Device", a "UM175AL CD-ROM USB Device", a "PANTECH UM175AL Diagnostic Port", and a "PANTECH UM175AL" modem.
By default, Linux only sees this device as a USB CD-Rom. As such, no serial port (e.g. /dev/ttyACM0) is ever created, leaving PPP nothing to connect to.
I need to thank Jason for responding to the comment I left on his post asking for help. Unfortunately, it appears that my "UM175AL" is a slightly different revision than what Jason used with so few issues.
As a sidenote, be aware of this CD-Rom emulation functionality while trying to boot from a real CD/DVD. At least under my Shuttle K-4500-N2, while my UM175 was connected, an external USB DVD-RW that was also connected wasn't given the chance to be used as a boot device. Instead, a boot attempt was made only on the UM175, which of course failed as there is nothing to boot from.
lsusb Note
Many pages I found while researching this issue referenced the output of "/proc/bus/usb/devices". This does not exist under recent versions of Ubuntu Linux. lsusb appears to be one of the preferred replacements. Some details are available in Ubuntu on launchpad.
USB_ModeSwitch
The closest I found to anyone having a similar issue was a post by "theosib" on the with a post less than a month old, "Total disaster trying to set up Verizon EVDO device". I replied with some details of my issue, after which "theosib" replied with what would turn out to be my solution - .
Be sure to read the main content on USB_ModeSwitch's main page at , as it is a pretty good summary of the issue.
Note that in my response on the UbuntuForums, I stated that when the device is properly recognized by Windows, the Vendor ID was 0x3715, compared to the current 0x3b03. So the goal is getting this to "switch" to 0x3715, at which point it should be (and is) properly recognized as a USB modem by Linux.
The download of USB_ModeSwitch comes with a precompiled executable,
but I'm guessing it was compiled for 32-bit, as it wasn't recognized on
my system. I recompiled it from the included source without any issues.
Just make sure the "" and "libusb-dev" packages are , as this isn't mentioned on the page. Following the notes on the USB_ModeSwitch page, I placed a copy of the output in "/sbin" as "/sbin/usb_modeswitch" using .
Given the about output from "lsusb", I already had the "DefaultVendor" and "DefaultProduct"
values needed to configure USB_ModeSwitch. Using these successfully
detached the storage driver, but didn't have any effect on the Vendor
ID or any apparent change on the output listed by lsusb.
Following the documentation, this most likely meant that I still needed
to send an additional special command to make the device "switch",
using the "MessageEndpoint" and "MessageContent" parameters.
The preferred tool to use to find these parameters mentioned in the USB_ModeSwitch documentation is "". The link is for version 1.8. For me, it would constantly and uncontrollably refresh the screen, making it impossible to scroll the device list and pretty much making it unusable. Fortunately, I found an updated version 2.0, based on the same source, at . (Source code is readily available for both versions.)
To sniff the necessary commands from this device, I found the VID/PID with the "unswitched" ID's. Specifically, "USB\Vid_106c&Pid_3b03&Rev_0100"
("PANTECH UM175AL Composite Device"). I then installed the filter, then
removed and reinserted the device. The following is my captured "UsbSnoop.log", with the necessary message portions highlighted:

Given the above information, I then saved the following as "/etc/usb_modeswitch.conf":
DefaultVendor = 0x106c
DefaultProduct = 0x3b03
MessageEndpoint = 0x05
MessageContent = "55534243904ed68a24000000800008ff024445564348470000000000000000"
The following command can then be used to "switch" the mode of the
device so that it is recognized as a USB modem. Note that as documented
on the USB_ModeSwitch page, most programs using libusb need to be run as root:
sudo /sbin/usb_modeswitch -c /etc/usb_modeswitch.conf

At this point, I was finally able to establish a connection using
PPP. This setting appears to even persist across reboots, as long as
the USB device doesn't loose power. Following the examples on the
USB_ModeSwitch page, I saved the following as "/etc/udev/rules.d/99-usb_modeswitch.rules" which will automatically run the above command whenever the device is detected:
SUBSYSTEM=="usb", ATTR{idProduct}=="3b03", ATTR{idVendor}=="106c", \
RUN+="/sbin/usb_modeswitch -c /etc/usb_modeswitch.conf"
Note that there is a "README" file in the "/etc/udev/rules.d" directory. Additional information can be found in the man page for udev ("man udev").
Accessing the Modem
The "cdc_acm" kernel module should now detect a connected device, and connect it to "/dev/ttyACM0".
Before making the Internet connection with PPP, the modem can be
communicated with as a serial device. I'm not sure what the preferred
method is for doing this under Linux, but the "" command (located in "/usr/bin") worked for me:
/usr/bin/screen /dev/ttyACM0

Signal Strength
The "AT+CSQ" returns the current signal strength as a value between 0-31, with higher being better. , this number indicates the signal strength above -109 dBm in 2 dBm increments.
I know the Windows client software displays a regularly updated signal strength indicator, even while the connection is active. It would be nice to have this functionality available under Linux, too, but it doesn't look easy, if even possible.
I found one forum thread with one response on the topic: . Pretty much, it seems that the data stream would have to be paused, the modem dropped to command mode, the "AT+CSQ" command issued and the value retrieved, then sending "ATO" to go back online. The forum response suggested that a modified pppd would be needed. I'm wondering if a "wrapper" tty couldn't be written that would be passed to pppd,
and query the signal strength whenever the connection is idle.
Alternatively, I'd be curious if the "diagnostic port" as shown in
Windows would provide similar functionality without having to interrupt
the data line? Maybe this is available by one of the other interface
descriptors shown in the lsusb output (above)? Maybe "bInterfaceClass 10 CDC Data"?
Update (2008-10-08): Sysinternal's shows that under Windows, the The Alltel "QuickLink Mobile" Wireless Connection Manager communicates with the "diagnostic port". Unfortunately, unlike the text-based "AT" commands used above, this communication looks completely binary. It also doesn't look to be easily decipherable, or to use any known standard. I've sent an email to UTStarcom, and can only hope for an unlikely helpful response.
Here's the output from about 5 seconds of communication with QuickLink Mobile and the "diagnostic port" using Portmon:

I just wanted to say thanks so much for all this info. I have the exact same card through Alltel and have gotten it working under SLED 10 thanks to your post.
I've compiled all the configuration into a blog post for openSUSE Lizards here:
Thanks again!!!
I periodically search Google for an answer to using Alltel's UM175AL under Linux, so I'm really happy to see your article! When I get a few days off, I'm going to attempt to reproduce what you've done here.
I'm a trucker, and I need Internet every single day when I'm on the road. It has really been vexing me hardcore that I am forced to use 32-bit Windows Vista on my new Toshiba laptop, just so I can get my Alltel aircard to work! 64-bit Ubuntu runs sweet on this machine, and even if I could run the 64-bit version of Vista, Vista is just plain ugly fugly crap no no no DO NOT WANT.
Thanks for documenting your solution!
Mark,
Thanks for the excellent instructions. I am trying to use my BlackBerry Storm as USB Modem with Ubuntu 8.10 and am having a hard time getting it to switch from “Mass Storage” to “Modem” using usb_modemswitch. Hope you can figure it out. Cheers! Karl
Link to file dumps:
%20EVDO%20BlackBerry%20Storm%20Ubuntu.txt
Karl - the link to your file dump is broken. Did you get it working under Windows? If so, were you able to use UsbSnoop to capture the MessageContent? (Or is that what the file dump was supposed to be?)
Sorry about the broken link Mark.
Please try this one:

Yes, Storm has been working with VZAccess Manager fine for the last few months. But I really want to lose Window$...smile.
Karl
Karl - in the version of usb_modeswitch.conf that you included in your dump file, I see there is already a section for "Option Verizon BlackBerry Storm 9530". The TargetVendor, TargetProduct, MessageEndpoint and MessageContent there all match the same bytes found in your output from UsbSnoop. However, I don't see that section in the latest available at Did you add them? If so, I assume you tried using them by uncommenting them (removing the leading semi-colons)?
Otherwise, I see a few other sections in the UsbSnoop dump that might also be replacements for what you have. Just trial & error, I guess. I don't have access to a BlackBerry, so I don't know how much more I can help.
Thanks Mark,
I didn't know that I needed to remove the leading semicolons.
Let me try that and if it doesn't work I would love to hear which sections of the USBSnoop dump might work. I will be back in a while.
Karl
Great advice re. semicolons Mark. Now I am a step further. The error message is:
"karl@ubuntu:~$ sudo /sbin/usb_modeswitch -c /etc/usb_modeswitch.conf

Karl - see the 2nd paragraph commented at the top of usb_modeswitch.conf regarding the use of "comment signs". It's pretty typical for these types of config files, but it's nice that they also have it documented there.
Regarding the error message, my guess is that you need to remove all the spaces from within MessageContent.
Looking at the default usb_modeswitch.conf, your MessageContent appears to be significantly longer than the others. Start from the beginning, and look for any sets of data after "URB # going down". You should be able to ignore any "URB # coming back" sections. At this point, I think it's trial & error, though someone on the USB_ModeSwitch forums may be able to offer additional advice.
OK Mark,
thanks a bunch for your support. Once I figure it out I will let the guys from usb_modeswitch know what works for the storm, so they can update the conf file. Cheers! Karl
The cdc_acm module is missing in the newest linux kernel. See my posts in ubuntuforums:
Another choice on getting the signal strength would be using a CMUX driver. The serial connection in some modems can be multiplexed. The AT command is AT+CMUX=1. This causes a binary protocol to take ove r the serial port. The CMUX protocol supports the usual PPP channel along with at least one more control channel for AT command to be delivered during the session. If a CMUX driver for linux was developed it could simply be pointed at the /dev/ttyACM0 and it would create 2+ pseudoterminals /dev/pty[X,Y,Z] through which AT commands and PPP could co-exist.
