First sorry for the delayed reply

But the Serial to USB modem works under 7.04 and 7.10 (i think) but
definitely not under 8.04 (hardy). So am reopening the bug.

Ok how it works under 7.04 is that i have been making a rules file under


the file is called

with the following contents
#TI USB 3410

SUBSYSTEM=="usb_device" ACTION=="add"
SYSFS{idVendor}=="0451",SYSFS{idProduct}=="3410" \

SYSFS{bNumConfigurations}=="2" \

SYSFS{bConfigurationValue}=="1" \

RUN+="/bin/sh -c 'echo 2 > /sys%p/device/bConfigurationValue'"

doing this make the OS attach the serial to USB modem to /dev/ttyusb0 and my wvdial work.

I upgraded to 7.10 and this continued to work

but i tried to make the same work under 8.04  and  this same process
does not work. Am not sure if its an 8.04 problem only or if a tweak is
required somewhere.

my wvdial file looks like this
[Dialer Defaults]

[Dialer 92]
Modem = /dev/ttyUSB0
Baud = 230400
Phone = #777
Init1 = ATZ
Stupid Mode = 1
Dial Command = ATDT
Username = XXXX
Password = xxxxx
PPPD Options = crtcts multilink usepeerdns lock defaultroute

So right now i am back at 7.04 and accessing the internet on the FWT
