I have been trying to get the HP 2300 Broadband Wireless Module (UMTS modem) to work with Ubuntu 7.10 (2.6.22 kernel) on my HP 2510p laptop without any luck so far.
The HP 2300 uses the Qualcomm MSM6280 chipset and the Sierra Wireless MC8775 module, which should be supported under Linux. The device is installed as a mini PCI card, and recognized as the following USB device:

In order for the system to load drivers for the device, I have created a file:
/etc/udev/rules.d/50-sierra-umts.rules
with the following lines:
SUBSYSTEM=="usb", SYSFS{idProduct}=="1e1d", SYSFS{idVendor}=="03f0", RUN+="/sbin/modprobe usbserial vendor=0x03f0 product=0x1e1d"
SUBSYSTEM=="usb", SYSFS{idProduct}=="1e1d", SYSFS{idVendor}=="03f0", RUN+="/sbin/modprobe sierra"
When booting, dmesg lists the following:
[ 33.700000] usbcore: registered new interface driver usbserial
[ 33.700000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/usb-serial.c: USB Serial support registered for generic

[ 33.836000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/sierra.c: USB Driver for Sierra Wireless USB modems: v.1.0.6
According to various documentation for the Sierra chipset, one should now be able to use /dev/ttyUSB1 as a modem, but when I run:
sudo pppd noauth nodetach /dev/ttyUSB1 user '' connect '/usr/sbin/chat ABORT BUSY ABORT "NO CARRIER" "" ATZ OK ATDT*99# CONNECT'
It just times out with the message "Connect script failed". If I use wvdial to connect to the modem, I get:
WvDial<*1>: WvDial: Internet dialer version 1.56
WvModem<*1>: Cannot get information for serial port.
WvDial<*1>: Initializing modem.
WvDial<*1>: Sending: ATZ
WvDial<*1>: Sending: ATQ0
WvDial<*1>: Re-Sending: ATZ
WvDial<Err>: Modem not responding.
Any ideas?
