USB Flash mounts the first time but not the second
 

I am having a problem with USB flash frives in a new PC. I have been using them fine in my old Pc.

I can mount the drive, use it and unmount it. But the second time I mount it I get errors. dmesg shows

What was the mount error ?

Alan,

This might not be your problem, but issue as root "/etc/rc.d/rc.hotplug restart"
and then try that device again.

It looks like you plugged in a flash disk, which may or may not have had problems.
Then there is "spurious 8259A interrupt: IRQ7." -- Did you Google for that?

Next there are those messages about a Wacom tablet, then you unplugged the device
apparently -> "usb.c: USB disconnect on device 00:0b.1-8 address 2"

Those messages look somewhat out of order. What is the output of "lsmod | grep -i usb" ?

I think the problem might have been due to the discs not being unmounted properly due to konqueror. I will get back if the problem recurs.
