Thread: HP un2400 Mobile Broadband Module

Hallo,

i've a HP Compaq 6730b Notebook (Intrepid) with an integrated HP un2400 Mobile Broadband Module.
I think there is a Qualcomm Gobi Chipset working on the card.

I've tested with "modprobe usbserial vendor=0x03f0 product=0x201d" but it will not work.
The dmesg output of the modprobe:

Code:

[   70.145900] usbcore: registered new interface driver usbserial
[   70.147565] usbserial: USB Serial support registered for generic
[   70.147622] usbserial_generic 4-2:1.0: Generic device with no bulk out, not allowed.
[   70.147639] usbserial_generic: probe of 4-2:1.0 failed with error -5
[   70.147694] usbcore: registered new interface driver usbserial_generic
[   70.147700] usbserial: USB Serial Driver core

Any ideas how to get the un2400 working?

Today I tried to modify the module "option.c":
Added the following:

Code:

#define HP_VENDOR_ID				0x03f0
#define HP_PRODUCT_UN2400			0x201d
{ USB_DEVICE_AND_INTERFACE_INFO(HP_VENDOR_ID, HP_PRODUCT_UN2400, 0xff, 0xff, 0xff) },

Modprobe of the modified option.ko returns:

Code:

[ 3422.081853] NET: Registered protocol family 10
[ 3422.083163] lo: Disabled Privacy Extensions
[ 3422.084935] ADDRCONF(NETDEV_UP): wlan0: link is not ready

But ttyUSB0 is not usable.

Can anybody help me?

Again some news:
I've installed Windows to see in detail what happens on activating the card.
The Windows-Driver first loads the firmware to the card.

I think that this is my problem. Without the firmware loaded the card will never work.

IMO on windows the firmware is loaded with the "Qualcomm QDL service".

Ideas?

I was thinking about getting an HP Notebook with this same functionality.

I sadly don't have any ideas for you, but agree that it would be great to see this working on Linux. (Ubuntu specifically)

Consider submitting a request for Qualcomm Gobi Chipset to Ubuntu Brainstorm

Why bother making a brainstorm to support a device the manufacturer doesn't offer proper Linux drivers for? Go hassle Qualcomm.

Thats right. Qualcomm has to deliver the Linux drivers.
But i'm a little unsure, if there is no driver, or i'm to stupid to get it working?
I'll write an E-Mail today to Qualcomm and HP.

hi,
i got the same problem with my 2530p elitebook.
did you get some answer's from HP or Qualcomm?

I think that HP will not help you because they only supprt SUSE

CU

Same problem.. I have HP 6930P. Hopefully somebody finds solutions, so we can use the whole potential of our laptops also with Ubuntu

I got an answer from Qualcomm

Thank you for your inquiry. QUALCOMM CDMA
Technologies is a provider of chipsets and
software technology for wireless devices and
network operators. We do not manufacture equipment or drivers.

Funny that they still advertise Linux support if it's not their business

I seriously doubt that there'll be any good news from HP on this.

Anyway... I think I'll just kill the idea of ever having it working. There are not enough Linux user's having this device to encourage a hacker to write a driver.

Hp should provide the driver. It is their device and they have the Mi OS (Linux) it is running on.
