USB Flash Drives are usually formatted FAT32 by default
USB support is already in most kernels by default
You can test like this..
tail -F /var/log/messages
That will tail the Messages log and then Follow the log file for any NEW messages that appear.
Afte you have issued that command plug in your USB device and see if any new messages appear on the screen. If they do then the system has detected your USB device and should assign a designator to it.
Code:
itg-debian:~# tail -F /var/log/messages

I Issued the command, plugged in my device it was detected as hda so I would mount it with the typical mount /dev/hda1 /mnt/mountpoint
As you can see it is also using the sd_mod and usb_storage modules to support the device.
This works pretty much the same for USB Drives, Memory card readers, etc..
Here is the output from a memory card reader..

Notice each card slot on the Memory card reader gets a different drive designation..
Hope that helps. |
