[Warty] /dev/ttyUSB0 changing to /dev/ttyUSB1 !!

[Santanu Chatterjee]

Hello all,

I am running Warty (fresh install). I am using a serial modem on a
presario-2203AL laptop through a usb-to-serial converter, which is
detected as /dev/ttyUSB0. However, after sometime, while on the net,
if the modem gets disconnected somehow, then more often than not,
I cannot use the modem via the same wvdial.conf file since the modem
still gets detected, but as /dev/ttyUSB1 not ttyUSB0!!  To fix this, I have to
pull out the usb cord and plug it back to get it detected as ttyUSB0.

Why this funny behavior?? Any help will be very my appreciated.

Thanks in advance.

Regards,
Santanu
