General :: Startup Script - Unable To Enumerate USB Device On Port 5

May 19, 2011

Startup script. I have a problem with an error on system boot:
hub 2-0:1.0:unable to enumerate usb device on port 5

This error is continuous, filling up my system logs. It is also a known kernel bug. I found a solution here: [URL] but it is only good after I boot. I have tried to make a startup script in /etc/init.d in the following manner.

sudo mkdir /opt/usb/
sudo gedit /opt/usb/usbproblem.sh
#!/bin/bash
# chkconfig: 345 91 19
# description: stop usb problem on startup
case $1 in
*)

echo "fixing usb problem"
cd /sys/bus/pci/drivers/ehci_hcd
sh -c 'find ./ -name "2-0:1.0" -print| sed "s/.///">unbind'
cd ~

esac
exit 0
#End of boot script
##

sudo cp /opt/usb/usbproblem.sh /etc/init.d
cd /etc/init.d
sudo chmod +x usbproblem.sh
sudo update-rc.d usbproblem.sh defaults 92 20
but it does not work.

Fedora :: Unable To Enumerate USB Device On Port 4

Jul 21, 2011

After installation I boot a few times and used F15 on my Dell Inspiron 1564. But now I can't boot anymore. The screen just shows "unable to enumerate USB device on Port 4" and just hangs there with a blinking cursor below that line. I have no USB devices attached though.

Slackware :: Unable To Enumerate USB Device On Port 5

Jul 16, 2011

I'm running Slackware 13.37 64 bit. I run it on an HP2945SE AMD Turion x2. I am getting an error during boot up unable to enumerate USB device on port 5. It filters throughout the rest of the boot up commands / results. It doesn't seem to matter if things are plugged up to the USB ports or not. Also it doesn't seem to affect anything on the computer. Its just irritating.

Ubuntu :: Unable To Enumerate USB Device On Port 4

Mar 4, 2010

Doing a dmesg I can see following lines

[ 130.876406] hub 1-0:1.0: unable to enumerate USB device on port 4
[ 130.876453] usb 3-2: USB disconnect, address 6

[ 131.396382] hub 1-0:1.0: unable to enumerate USB device on port 4

[code]....

That is what I have exactly pluged, the webcam on the top of my screen and an external mouse. Btw, I can plug USB devices with no problem, so I am skiping this error since long time ago, but I don't understand this message and I would love to do it.

Ubuntu :: 10.04 Booting Slow - Unable To Enumerate USB Device To Port 1

Recently my Ubuntu 10.04 was booting slow and to figure out what was going wrong, I booted Ubuntu in text mode. There I found it was hanging on for 5-6 sec showing "unable to enumerate usb device to Port 1". I know it has something to do with Port1 / usb device, but could not understand and solve it.

OpenSUSE Hardware :: 11.4 Getting "hub 2-0:1.0: Unable To Enumerate USB Device On Port 5" Constantly

CentOS 5 :: 5.4 & "kernel: HUB 1.0:1.0 Unable To Enumerate USB Device On Port 1 (or 2, 3)" And Stops After Logging (text Mode)"

Mar 22, 2010

I installed Centos 5.4 on my Pentium E5300 new comp, but I need IPX support in my work. It's simple - ipxutils and ncpfs from Fedora Core and new kernel with ipx support. I copied kernel config from /boot folder and activate ipx, ntfs support, and choose processor core 2 duo. New kernel (2.6.26) works OK, but I got one problem - when start it still shows message: "kernel: HUB 1.0:1.0 unable to enumerate USB device on port 1 (or 2, 3)" and stops after logging (text mode)

I got 2 USB devices connected - printer HP D5160 PhotoSmart and Scanner A3 USB Mustek, and I know scanner cause that messages but I don't understand why. Kernel config is the same like that from distro kernel (almost - ipx, ntfs and proc), but distro kernel doesn't do that. So I got 2 questions:

1. Why
2. What to do to stop that (disconnecting devices on boot time is not a solution)

Debian Hardware :: Unable To Enumerate USB Device

Jul 26, 2010

I noticed this message "hub 1-0:1.0: unable to enumerate USB device on port 4" appear before the kernel says "no resume image found loading normal init" or something along these lines. Basically what I mean is, this message shows up whenever the kernel loads. So I checked if anything is logged in /var/log/messages (are messages like these logged???), did not find anything in the log.

I then used this command, which showed up the message I was looking for.
dmesg | grep -i enumerate [    2.379748] hub 1-0:1.0: unable to enumerate USB device on port 4

My USB mouse and other USB hard drives are working fine, without any problem. I just wanted to know if this is some kind of bug. I did some search I found this link , [URL], where this kind of bug was discussed. Looks like they closed the bug.

here is my lspci output:

General :: Use A Rs232 Device That Uses The Usb Port?

May 18, 2010

been trying to use a rs232 device that uses the usb port. it calls for a virtual com port to be created. i am running on ubuntu 10 and get hella confused with the search results i have come across.some call for the usbdevfs which apparently doesn't exist under lucid. another had me do use some "magic" in getting it to work.they provided a script mountusbfs.sh

Code:

#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs

[code]....

of course when i tried it the domount command doesn't exist so i modified the above script replacing the domount with mount and it seemed to do something things. usbview is specified as the determining factor whether or not you have the usbfs mounted properly. it wants to use proc bus and ubuntu doesn't use that anymore apparenlty. i have read that i need to enable a usbmon (flag?option?) in the kernel to be set. which it isn't when i followed the steps to check.

General :: Can't Find Boot Device - Error "Unable To Determine Major/minor Number Of Root Device"

Mar 17, 2011

I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:

I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:

Ubuntu :: Port Forwarding Crutch - Number Of Apps That Are Unable To Have The Outgoing Port Changed ?

Mar 28, 2010

I'm not that great with mailservers, and just been thrown a curveball with a MS Exchange environment for which there is apparently no solution... yeah, right. But is there a workaround?

The problem is that the site mail (SMTP) needs to be sent via port 26 instead of the commonly used 25. Port 25 is mapped to a mailfilter, which apparently causes havoc with some of the mail, and the techs that have been on site trying to coax the Exchange server to co-operate have said that the only way would be to get rid of the filter.

The problem is that there are number of apps that are unable to have the outgoing port changed and so keep sending mail out on port 25.

I look after the Unix/Linux side of things at work, and I was wondering if there was an easy way to set up a Ubuntu box to receive mail on port 25 and just forward it to the MS box on port 26? So, in other words (and I hope this makes sense): monitor port 25, and forward whatever comes in on port 25 to the server on port 26. Simple portforwarding, or is it? What steps do I need to take?

General :: Unable To Close SSHD On IPv6 TCP Port?

Aug 23, 2011

I'm running Ubuntu 10.4 and I've tried disabling IPv6 as I don't currently need it. I rand the following to disable IPv6 and then rebooted my server:

echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf

After the reboot I can see that IPv& is disabled by running:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

On running netstat -antlp i see that most of the IPv6 applications have closed but SSHd keeps running:

Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:9090 0.0.0.0:* LISTEN 663/java

[Code]....

Ho can I close the SSH daemon on port 22 of the IPv6?

General :: Unable To Access Port 8008 From Web Browser

Jan 22, 2011

So this is my first post so I'll put it in "Newbie".I seem to have successfully configged my httpd.conf file to listen on port 8008. I restarted httpd ok. However, when I go to port 8008 in a web browser from another computer on the internal network by going to 192.168.2.5:8008, it doesn't connect. When listening on port 80, I can browse to the IP address fine. is this a server-side or client-side issue? Using Fedora 12. Thanks in advance and tell me what forum this would best fit in.

General :: X11 - Unable To Add Any Port Forwarding Rules To Router

Feb 22, 2011

Say I have Computer A behind a router with NAT. I'm unable to add any port forwarding rules to that router. Then I have Computer B with a public IP address that I want to forward X windows from. This computer is headless, but does have a video card so X windows can be used. Here are some of the things I'd perform to setup my scenario.

1. Computer B, I'd run xhost + public_ip of NAT router.
2. Make sure that computer B's sshd service has X11 forwarding enabled.
3. SSH from Computer A to Computer B with the X windows forward option.
4. Once in Computer B, set the DISPLAY env variable to the public_ip of NAT router.
5. On Computer B run xclock.

At this point I'd expect to see an instance of xclock originating from Computer B onto my desktop. However this obviously won't work. The problem is that when the request is made to Computer B to forward the instance of xclock to Computer A the forwarded instance of xclock will get stuck at the NAT router. Without a port forwarding rule the NAT router will not know which internal IP to route the instance of xclock.

Here's my question. Is there any way for Computer A to initiate a connection to Computer B and then forward the instance of xclock? That way if it uses that same connection the NAT router will know which internal IP to route it to because it would be an active connection in the router's routing table. Or is there an alternative? Of course I can vnc into another computer outside the NAT network and then forward an X window to it just fine. But in the spirit of expanding my knowledge on X windows I'd like to see what is possible.

General :: Unable To Get Internet Connection On Startup

Sep 22, 2010

When I boot up my machine (running CentOS 5.5), I have no internet connection. ifconig doesn't show that eth0 is present. Going into my Network Gui from the administration tools, it says that eth0 is not active. I can't activate it from the GUI.But...If I sudo dhclient -d eth0, the process runs for a little bit, and all of the sudden my internet connection is there.

There must be some sort setting that I need to change to avoid doing this everytime I start the machine. Its odd, because I have an identical machine right next to it that doesn't have this problem.

General :: Unable To 'mount' And Use Itouch 8Gig Device / Fix It?

Jan 7, 2010

What do I call this device in /etc/fstab. Currently the line I'm using is... code...

Having made a mount directory (/media/ipod) an error message tells me
... mount: special device /dev/sdc0 does not exist...
when I try to mount it.

I cannot see it in 'gparted' or 'disk utility' but I can see it on sys log and kern log when I plug it in and remove it.

I have visited several help forums and loaded several types of recommended software (ifuse-libs and mux's etc) but with no satisfactory result.

I have successfully 'Jail broken' the device using 'Blackra1n' on a windows machine.

It used to appear on the desktop but alas...no more. I've obviously broken something!

General :: Drivers - Unable To Activate Wireless After Device Has Been Re-enabled

May 8, 2010

Using a Eee 900A netbook by Asus. By pressing Fn + F2, I can disable or enable the wireless chip on the netbook, a blue LED indicates the status. I've been able to connect to wireless networks just fine with this netbook. However, if the wireless chip ever becomes disabled, I have to reboot to get my network connection back. This generally happens when suspending. For some reason the LED will be off and I have to hit Fn + F2 for it to light up again.

However, after doing so, Linux will not reconnect to the network. It simply changes the wireless status from "wireless is disabled" to "device not ready". Even worse, I've recently had issues with the chip being enabled at boot, thus making it nearly impossible to get connected. I've searched around on-line but haven't found much of anything useful on this. This happens on all kinds of different distros including Ubuntu 9.10 Netbook, EeeBuntu 4 beta, Jolicloud and Ubuntu 10.04 Netbook.
