I've made some progress, thanks to quite a few others out there posting. I'm going to attempt to be methodical and post hopefully useful info: PROBLEM: When plugging in my 3G EVDO USB card, it's not being recognized via KPPP, GNOME PPP or Mobile Partner. I've tried just about every port within the options of KPPP and always immediately comes up with an error (Please make sure you have setup your modem device properly and/or adjust the location of the modem device on the modem tab of the setup dialog). Op Sys: Linpus Lite 3G Card: Sierra Wireless 598 (made by Qualcomm, as the micro-sd card slot in it) 3G Provider: Sprint Steps taken to recognize card: 1) Installed Sierra Wireless drivers 2) Started to setup the "usb_modeswitch" The 3G card is now recognized in dmesg and if I do a modinfo for sierra it returns the drivers. However, if I try to use on any port it doesn't recognize a modem connected. I've tried the applications listed above to connect, and they all act as if therej's no device attached. Here's a snippet of dmesg that shows the Sierra Wireless being detected, but changes from being a USB Modem to storage. Can anyone glean something from it that may help? Let me know if more info is needed. usb 2-2: new full speed USB device using uhci_hcd and address 3 usb 2-2: configuration #1 chosen from 1 choice usb-storage: device ignored usbcore: registered new interface driver usbserial drivers/usb/serial/usb-serial.c: USB Serial Driver core drivers/usb/serial/usb-serial.c: USB Serial support registered for Sierra USB modem (1 port) drivers/usb/serial/usb-serial.c: USB Serial support registered for Sierra USB modem (3 port) sierra: probe of 2-2:1.0 failed with error -5 usbcore: registered new interface driver sierra drivers/usb/serial/sierra.c: USB Driver for Sierra Wireless USB modems: v.1.2.5b usb 2-2: USB disconnect, address 3 usb 2-2: new full speed USB device using uhci_hcd and address 4 usb 2-2: configuration #1 chosen from 1 choice scsi3 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 4 usb-storage: waiting for device to settle before scanning usb-storage: device scan complete scsi 3:0:0:0: Direct-Access Sierra Wireless Storage 2.31 PQ: 0 ANSI: 2 sd 3:0:0:0: [sdb] Attached SCSI removable disk sd 3:0:0:0: Attached scsi generic sg1 type 0

It looks like your system is trying to see it as a storage device and not a serial USB modem. Maybe you selected the wrong option when installing the software? __________________ Sometimes, real fast is almost as good as real time.
