Hi,

I'm trying to install a USB 3G modem, a HUAWEI E220, but when I run

# comgt -d /dev/ttyUSB0

I get the error:
"[root@deckard files]# comgt -d /dev/ttyUSB0
comgt 19:12:30 -> -- Error Report --
comgt 19:12:30 -> ----> ^
comgt 19:12:30 -> Error @74, line 4, Could not write to COM device. (1)"

I've google about, but find anything useful.

Any ideas ?

Any help would be appreciated.

Warm Regards,
Mário Gamito

I tried HUAWEI E220 on my laptop (Ubuntu 7.10 with 2.6.22-14-generic) and it worked fine for me!

Check whether the necessary UDB drivers are loaded..

What do:

ls -l /dev/ttyUSB0
fuser -v /dev/ttyUSB0

show?

Cheers
