Sprint (Franklin/CMOtech) U301 wireless modem
 

Trying to get a U301 (CMOtech 16d8:6008), under Fedora12, without luck. I've tried the "official" (unsupported) instructions from Sprint [sprint.com/pcsbusiness/downloads/Sprint_Mobile_Broadband_Setup_Guide.pdf] as well as many tips from the various Ubuntu and Fedora forums without success.

Also tried the "modprobe -v option" with "echo "16d8 6008" > /sys/bus/usb-serial/drivers/option1/new_id" and still can't get kPPP to recognise it.

I followed the kPPP setup instructions in the PDF and, when I query the mdm, I get "Unable to open modem"


Any ideas? Thanks much.

Did you happen to find a fix for this one?

Based on the input from your post, and after trying a few things, I got it to work with these instructions:

This is certainly not the most eloquent or the best solution, but it worked for me..

As root, issue lsusb after plugging on the device. Note the “CMOTECH” and the vendor/product numbers to the left. These instructions are for 16d8/6008...

Unplug the USB device, then add these lines to /etc/udev/rules.d/50-udev.rules

SUBSYSTEM=="usb", SYSFS{idProduct}=="6008", SYSFS{idVendor}=="16d8", \

Reboot

Issue “sudo wvdialconf”

Use your favorite editor and edit wvdial.conf like this one:

[Dialer Defaults]
Modem = /dev/ttyUSB1
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
Phone = #777
Username = ''
Password = ''
Carrier Check = no
Stupid Mode = yes

Plug in the USB Modem. The dmesg command should show something like:
