Prolific USB-Serial Controller
I am trying to a access a switch connected to a USB-Serial controller to my laptop's USB port. When I plug in the USB port to my laptop I get the following in my /var/log/messages. But I am not sure which /dev/ to use in minicom to access the switch. I can see there is no /dev/uplcom0 or /dev/ucom0 or /dev/uhub1. I tried /dev/tty00, /dev/tty01, /dev/tty02, /dev/tty03 and /dev/cua00 but minicom says device not configured. Any help would be much appreciated. Thanks.

Thanks. for USB-Serial controllers you have to use /dev/cuaU0 (callout) or /dev/ttyU0 Sigi

Thanks. I tried both /dev/ttyU0 and /dev/cuaU0 in minicom. They both
seem to go to the "initializing modem" phase but when I turn on the
switch with "/dev/cuaU0" configuration, minicom doesn't show anything
on the screen and minicom with /dev/ttyU0 configuration throws out
garbage characters on the screen -
..5%(.!3..=.3'=./A-#-.'!=7A/5'.5;!!. .-.9/.('5.
..5%((W/5(3!''!.-#1(9!%%=#7.(.-''(-#-.-='-53'=./(3-'5.
..5%(/=.(;55#(-#.5..57(.!.!(-#-.-='-.=..=..9..9.9.O%!75%(3-
Here's my minicom rc file -
pu port /dev/ttyU0
pu baudrate 9600
pu bits 8
pu parity N
pu stopbits 1
The USB Serial converter is detected as "Prolific Technology Inc.
USB-Serial Controller
rev 1.10/3.00, addr 2" in /var/log/messages.
Thanks for any further help on this issue.
Re: Prolific USB-Serial Controller
A) don't bother initializing a modem. Forget minicom. It's nearly
useless for what you're doing.
B) openbsd has a utility built in to do just these kinds of things:
"cu(1)"
C) to use cu(1) with a USB serial: "cu -l /dev/cuaU0"

try "cu -l cuaU0" - man 1 cu.
also, what is the speed of the serial console on your switch? verify
what that the default is, then apply -s accordingly. you may also toy
around with tip(1).

Should I try changing the baud rate? This Cisco 3950 switch is usually connected at 9600 baud rate via serial console.
