Hi,

I am unable to see the USB drive plugged in.

Fdisk -l is also not shoing the USB.

May I know what to do.

Why it is not automatically detected as like in widows.

New to linux and this is my fist install of linux on my Dell M4600 laptop.

Check in /var/log/messages to see if it shows up when plugged in.

What filesystem is in use on the disk? If it's NTFS then CentOS has no NTFS support out of the box - you need to add the third party yum repo "EPEL" using yum --enablerepo=extras install epel-release and then yum install ntfs-3g

File system is FAT.

I have observed that whiling booting up the machine I am receiving the following error:

usbserial: usb_serial_init: - usb_register failed
usbserial: usb_serial_init - returning with error -19

How to fix this?

Your help is deeply approciated.

Try a different USB port. Try plugging it in to a powered USB hub (i.e one with its own power supply).

That looks more like a USB serial port problem than a USB drive problem.

Hi All,

I am receiving the usb intialization error while booting.

usb_serial_init - initialization failed
usb_serial_init - returning with error -19

Because of this my USB ports are not working. Can any one share How to reinstall the chipset drivers.

Will yum update kernel will do what i expect.

Post the lines around those too. That sounds more like whatever USB device you are plugging in is being misdetected as a serial port...
