FC8 no /dev/USB?

linux-howto

http://forums.fedoraforum.org – Howdy, thanks for viewing this thread. I'm currently trying to console (AUX) into a cisco router in FC8 using minicom. I've read a few tutorials that walk you through the process of doing so..all of which seem to use /dev/ttyS* or /dev/ttyUSB* Since I don't have a DB-9 serial port on my laptop I'm using a USB adapter to rs-232 adapter cable. I plug in the cable and boot the machine...it's my understanding that the system should recognize it and list the device as /dev/ttyUSB* ...but when I view the contents of /dev i only see ttyS0 - ttyS03, some usbdev items, usbmon0 - usbmon2, and a /dev/bus/usb (directory containing 2 sub directories 001 & 002) I've tried opening each of these using minicom with the standard 9600 bit rate..and I get nothing...or some strange characters (when I press ENTER when usbmon0 & 2 configured) Do i need to setup ndiswrapper to use a recognized windows driver? when i view dmesg it doesn't even look as if the device is recognized. I'm lost... (HowTos)

Stories similar to FC8 no /dev/USB?

Hi,

I have a usb serial adapter and was happily using minicom with it under openSUSE 11.2. I've upgraded to openSUSE 11.3 and I can only use minicom with this serial adapter as root. I had previously had problems writing to /var/lock under openSUSE 11.2 which I worked around by changing the minicom config to use /tmp as its lock file location.

Multiple minicom session 2 years 30 weeks ago

Hi everyone,

Is it possible that I can run multiple session of minicom in a server? For example, 3 USB to Serial cable connecting to 3 console port device from a single server. /dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 and created 3 different minicom config for each. Then 3 different users are accessing 3 different console using minicom.

Hi Mod, If there's thread like this, kindly redirect me.

Tha

so I have a serial device interfaceing with my laptop on ttyUSB0. the device has an onboard serial to usb adapter, so it is recognized as a serial device. I have sucesfully used minicom and cutecom to listen to the device and see the expected output in the terminal. However to change the settings on hte device i must send the esc key followed by the command.

I am using Prolific Technology PL2303 Serial Port on Dell T1500, with Ubuntu 11.04

# lsusb Bus 001 Device 022: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

The device ttyUSB0 can show up on PC, and minicom/gtkterm can be started on this device. However, during the usage, there will be data lost.

Hi,

I am not sure, if this is right place to post this question.

I am trying to read out data from serial port using Minicom. I think so that when my program write a character with value 0, the minicom omits the data somehow. I don't see 0 or NULL character in the output. I don't know how to resolve this problem.

Thanks,

Pranav

minicom stays offline 4 weeks 6 days ago

I have Fedora 15 PC and tried to open minicom for serial terminal access. However minicom stays offline even though I set serial device to the correct one, dev/ttyUSB0. I'm using usb uart adaptor with cp201x drive. When I use the same usb uart adaptor in Windows and use tera term to open up serial terminal. It works fine.

Have tried methods from every thread I could find for past 10 hrs. Have tried installing rt3070sta etc. Monitored message log; appears that the driver isn't recognized, though the USB port sees that something is plugged in (when I plug in the adapter, and unplug it).

All of the threads miss something; I can't get a wireless port listed under ifconfig no matter what I try.

I fumblefingered the serial port setup for Minicom, and now it ALWAYS finds the incorrect settings.

I have the loopback cable connected from my server to the CISCO router. The router is connected to the router in the office with a crossover cable. It is connected to Lan port 4 (Linksys) and the cable is plugged in to the WAN port(CISCO).
