USB Memory Stick & Digital Camera Fight

[Mudelf]

Hello folks -

Guess this is a hello on my first post and a question:-

I live in Oxford, England and am definitely a newbie to Linux although im getting better ........ slowly ....


Eitherway, here goes ...

I have a USB Memory stick and a digital Camera which I connect through the USB -

My Laptop has only ONE USB port so I have to swap them over.

I can connect BOTH no trouble. Problem is once one has been mounted then I cannot unmount and then remount the other device. Something in Linux is stuck on the old device - any clue how I can determine what to do?

Also I just installed Debian 3 on my desktop machine and cannot mount my USB Stick at all -

Hotplugging is installed (I think) and DMESG is returning the USB messages which I think means that it can see the Memory stick -

I have tried cycling through various locations in /dev/ which worked on my Laptop and the Older RedHat I had installed on this same box but I cannot find the device !

Anyone know of some kind of auto mounting dev probe device that will scan your drives?

or something ...

Any ideas on this ?


Thanks ....

where do you mount it?

do something like this:

lsof | grep mntpoint and you should get the pid and be able to close it.. Good luck

Hang on let me just narrow this down:-

So you are are saying that once I have mounted EITHER my Cam or Memory stick and then unmounted one of these with the intention of mounting the other one a PID is still remaining open in some fashion and it is this which is preventing the NEXT mount attempt with the new device from proceeding ?

(At work at the mo without my camera but I will be trying this as soon as I get get home)

- thanks for your advice !

No, not quite what I meant. If you for example are copying pictures from your mem.stick with konqueror ( just an example ) and you forget to close konqueror or it crashes or something, knowing the pid can help you clear up whats clogging up the mnt-point. It has happened to me a couple of times using a cdrom.

The second one, sorry don't know, try to log in the usual spots, like system logs, dmesg, etc

Good luck
