Using multiple USB devices
 

I was just wondering if I can use multiple USB devices at the same time.

Scenario: Dell Latitude laptop with 4 port USB 2 pcmcia card running Fedora Core 3 (and latest 2.6 kernel). There is also a seperate USB 1.1 port that I have a USB modem attached to, that runs with no problem.

* I can plug in USB memory stick by itself and it is recognised.
* I can also plug in ipod by itself and it is recognised.

However, I cannot have both plugged in at the same time. It just freezes the system.

The conflict seems to be in that the device /dev/sda is used for both USB devices.

ie. ipod uses /dev/sda, /dev/sda1 & /dev/sda2

USB stick uses /dev/sda & /dev/sda1

Is there a way to use both at same time?

Any pointers appreciated.

The first disk would be sda and then the second sdb and the third sdc, and so.
The number stand for the partition number on the given device, on your ipod your music it's stored on sd*2 because it's hat two partitions and the first it used to the firmware.

Problem solved - just needed to update some system packages. All is working well, apart from the odd system crash upon shutdown?!? (shutting down from both Gnome & terminal)

Congrats on solving the problem and thanks for posting back with the solution chestnut. Would you be able to list the packages that were needed? That would be a major help to any future readers who might have the same question. Thanks! -- J.W.

ok, problem seemed to be that I only updated the Kernel to 2.6.11-1.14 (FC3) (from 2.6.9)

I also needed to update..

autofs
all packages in system-environment base
usbutils

(plus any dependancies for each)

Using a full update of installed system packages would do the trick. I only have access at present to a dial-up connection :( so download is kept to the miminal for the time being!

Awesome, thanks chestnut -- J.W.

and on a final note, the following document is VERY useful!
