unable to enumerate USB device on port

18 March 2009 - 04:30 PM

I can't get my USB device to work. When I plug it in and take a look at /var/log/messages I see this (repeated many times)

Mar 18 20:27:15 linux-n949 kernel: usb 1-5.4: new high speed USB device using ehci_hcd and address 63
Mar 18 20:27:16 linux-n949 kernel: usb 1-5.4: device descriptor read/64, error -71
Mar 18 20:27:16 linux-n949 kernel: hub 1-5:1.0: unable to enumerate USB device on port 4

Anyone know how to fix it?

Error during list population: cannot operate...

08 March 2009 - 09:03 AM

When I use the Spritz Package Manager I get this error:

Error during list population: Cannot operate on a closed database., Retrying in 1 second


But it doesn't ever appear to "retry". Anyone know the fix?

How can I tell if a cron job executes?

How can I tell if a cron job executes? Are there logs or something that I can check to make sure everything happened like it should?

types of man pages (man1, man2, man3, etc)

17 January 2009 - 06:14 PM

I found where the man pages are located on my Linux machine. Once I get into the directory I expected just one directory but there are a whole bunch.

man1    man2    man3    man4    man5    man6    man7    man8    man9    mann    whatis

What are all of these directories? Which one does the "man" command use? Each directory has files in it and they will have the .x where x is the number as their extension. Here is an example in man4 dir:

arp.4           faith.4         icmp6.4         ip.4            ipsec.4         null.4          stderr.4        tcp.4           udp.4
bpf.4           fd.4            ifmib.4         ip6.4           lo.4            pty.4           stdin.4         termios.4       unix.4
divert.4        gif.4           inet.4          ipfirewall.4    netintro.4      random.4        stdout.4        tty.4           urandom.4
dummynet.4      icmp.4          inet6.4         ipl.4           networking.4    route.4         stf.4           tun.4

They appear to just be text files though and can be loaded in any text editor.

Extend LVM Size

16 January 2009 - 07:07 PM

I need to extend /home. What command do I use? Do I use lvextend to add more space to this partition?
