How do i detect a USB device from the Linux Box

Dear all,

I have a USB device connected to Linux BOX running 2.6.10 kernel (F3).

I am able to mount read/write to the device with NO problem.



I find the following messages at attach time:-



usb 1-3: new high speed device using ehci_hcd and address 5

scsi4: SCSI emulation for USB Mass storage devices

usb-storage: device fount at 5



This are the messages are generated when I have plugged in my USB to the
system.

The address value & the device found value keeps on increasing for every
plug-in.



I find the following messages at detach time:-



usb 1-3: USB disconnected, address 5



The address value & the device found value keeps on increasing for every
plugin



What is it doing?

Do I need to run something like " detach the device safely" before
detaching the USB-device?



Thanks & Regards,

Mukund Jampala

Re: How do i detect a USB device from the Linux Box

Assuming it's some sort of storage device you're using -

I'd say, *before* unplugging the USB device, you need to un-mount it with
the 'umount' command
(and wait until the linux prompt comes up on the command line again, to make
sure it's finished writing everything to the USB device, *before* you unplug
it)
