Hi,

I recently installed gOS 3 on my laptop LENOVO G400.
USB Flash drive, Ipod and External USB HDD are able to detect and working fine.

gOS has wine installed and Installed a windows game and run it but my laptop gets hang and I can't even go to tty2 or any terminal to kill the process. My mouse pointer doesn't even move so what I did is to turn off the laptop.

After boot up, my USB Flash Drive (4GB), Ipod Video (30GB), and External USB HDD (320GB) are no longer detected even using # sudo fdisk -l

It only detects my laptop hdd.

I check the dmesg and use the udevmonitor and got the following when I plugged in those USB devices.

$ dmesg

What I did as well is to load the gOS LiveCD and boot it and check if those USB devices are able to detect and they were detected.

I copy the following dmesg log:

$ dmesg

And notice that when doing $ lsmod | grep -i 'usb' the module usb-storage is loaded.

When I boot up my gOS installed on my laptop, it doesn't have usb-storage module loaded.

I tried the below command but it doesn't help. Also try to put -r option on it.

$ sudo modprobe usb-storage

Tried insmod as well with its full path but it doesn't help.
My USB Modem is able to detect, my CD/DVD rom works fine.
This USB Storage only is having a problem.

2.6.24-19 is the kernel of my gOS 3.0

I tried the following as well but doesn't help.

$ sudo modprobe -r ehci_hcd
$ sudo modprobe -r uhci_hcd


Please help.



Thanks.

try googling for
"usb-storage: waiting for device to settle before scanning"
There's a reply to a similar problem on this site(http://www.linuxquestions.org/questi...ce-usb-323912/) which says:

"What are the permissions of the device?

/dev/bus/usb/###/###

I just chmod'ed my Creative device to 7777 when gnomad2 barfed, and now it works fine."

It seems as if your devices are still mounted as far as usb-storage is concerned, because of your hard lockup perhaps - worth a try
