3g Modem + usb-modeswitch kernel error

["Sergio Charpinel Jr." <sergiocharpinel@gmail.com>]

Hi,

I have a 3g modem MSA110UP connected to a updated debian squeeze machine. I use usb-modeswitch because this device is not switched by the kernel. I also use wvdial to connect.

After some time (2 days), I receive 10 "kernel: [222393.073561] option: option_instat_callback: error -84" messages, and my devices are disconnected:

kernel: [222393.176110] usb 1-2: USB disconnect, address 2

kernel: [222393.181527] option: option_instat_callback: error -84

kernel: [222393.181940] option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0

kernel: [222393.182040] option 1-2:1.0: device disconnected

kernel: [222393.182422] option1 ttyUSB1: GSM modem (1-port) converter now disconnected from ttyUSB1

kernel: [222393.182464] option 1-2:1.1: device disconnected

kernel: [222393.182671] option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2

kernel: [222393.182710] option 1-2:1.2: device disconnected

pppd[9358]: Modem hangup

So I have to reconnected the modem.

Any ideas?

Thanks in advance.
