Dear all A lot of google searches reflect that, the latest kernel supporting Huawei EC321 CDMA PCCARD is 2.6.17. My version (2.6.22-14 on Ubuntu) doesn't work.
I am not sure if I should file a bug somewhere or how to contact the right person. I see another version of this card (Huawei E220) was discussed on this list and so I though this is the right place to post this information. Redirect me to someone else if I posted in wrong place, thank you. I can give away my card to someone if they can use it to modify driver to add the support back. I can also type some commands and get you the result if you ask me to. What I cannot is describe it technically good enough to show the problem without other's prompt/help. I also cannot debug program or read source code. I need to emphasize this is a very common model card in China mainland, it's the "default" one, many of my friends has it. So it make sense to get the support back. dmesg on 2.6.22-14 (that doesn't work): [ 3802.596000] usb 7-1: new full speed USB device using ohci_hcd and address 2 [ 3803.756000] usb 7-1: new full speed USB device using ohci_hcd and address 4 [ 3804.024000] usb 7-1: configuration #1 chosen from 1 choice [ 3804.132000] usbcore: registered new interface driver usbserial [ 3804.132000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/usb-serial.c: USB Serial support registered for generic [ 3804.132000] usbcore: registered new interface driver usbserial_generic [ 3804.132000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/usb-serial.c: USB Serial Driver core [ 3804.140000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/usb-serial.c: USB Serial support registered for pl2303 [ 3804.140000] pl2303 7-1:1.0: pl2303 converter detected [ 3804.140000] usb 7-1: pl2303 converter now attached to ttyUSB0 [ 3804.140000] pl2303 7-1:1.1: pl2303 converter detected [ 3804.140000] usb 7-1: pl2303 converter now attached to ttyUSB1 [ 3804.140000] usbcore: registered new interface driver pl2303 [ 3804.140000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver [ 3804.148000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/usb-serial.c: USB Serial support registered for GSM modem (1-port) [ 3804.148000] usbcore: registered new interface driver option [ 3804.148000] /build/buildd/linux-source-2.6.22-2.6.22/drivers/usb/serial/option.c: USB Driver for GSM modems: v0.7.1 this is how it doesn't work: [EMAIL PROTECTED]:~$ sudo wvdial WvDial<*1>: WvDial: Internet dialer version 1.56 WvModem<*1>: Cannot get information for serial port.

I am not sure if this is the case, because I could not find the phase "3G data card" in drivers/usb/serial/option.c in 2.6.22-14 kernel, this phrase existed in 2.6.17 in option.c For your information, EC321 is a CDMA card, in sales people's words, it's way too different from GSM. I am dumb on this anyway.
