Hi,

I am trying to connect a GSM modem to my laptop (running linux). I used Wvdial to get connected. When I type dmesg command it shows that the USB port connecting the modem is detected. But the error is displayed as No Carrier.

What could go wrong? After some searching I found the problem was related to USB Drivers. So I wanted to reload the ohci_hcd module.

When I type:

modprobe -r ohci_hcd

The following is displayed

FATAL: Module ohci_hcd not found

What could be the reason for the error?? How can I fix this??

Cheers!!

It might be compiled into the kernel, not as a module, or you could be using a different driver. My system uses ehci_hcd and uhci_hcd for USB drivers.

My system uses ohci_hcd module. I found this out by typing the command

tail -f /var/log/messages

This shows a new USB driver is installed using the ohci_hcd module and address 4.

So If it is compiled into the kernel how can I reload it. Because I guess my modem is not being detected due to problems in the ohci_hcd module.

I look forward to your suggestions.

Cheers!!
