USB_ModeSwitch

Hi guys,

i tried to read a lot, but i cant get to work my USB dongle on my centos 5.6 server.
what i read from lsusb is:
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
Bus 001 Device 003: ID 12d1:1436 Huawei Technologies Co., Ltd.
Bus 001 Device 005: ID 413c:0000 Dell Computer Corp. DRAC 5 Virtual Keyboard and Mouse
Bus 001 Device 002: ID 413c:a001 Dell Computer Corp. Hub
Bus 001 Device 004: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0 "TetraHub"

i haven't modified the defualt /etc/usb_modeswitch.conf, just changed to log.

when i boot my server or i restart the udevs. i see the following, that is the opposite of what i expect:

i would expect to see the device is attached and not disconnected, i did some test on a centos 5.6 on a laptop and it was working, awfully i can't remove the usb dongle and reattach it, 'cuz its im ny datacenter that is far from my office

then there is one thing i dont understand/know: how to determine which is the target for my device to became a serial for the modem ? and dont use it as storage ?

i see 12d1:1436... is it in storage mode or serial mode ? how to check it ?

please help me, im not able to send sms messages

best regards,
Luca

I have no idea what is happening on your system ... Probably some security response?

Anyway, to check the mode of a device run "lsusb -v -d <ID>", in your case:See if the first interface has class 8 (CDROM mode) or class 255 (modem mode).
