Unable to mount USB storage devices

I've had this problem since like more than a month ago (2.6.29). USB storage devices, e.g. flash drives, get detected, registered as a storage device, then get de-registered immediately.

FYI, I'm using the latest stable packages (x86_64).

I don't remember (I'm actually quite sure that I didn't) changing any config files related to udev/USB/storage devices that's why I'm quite stumped and I don't know how to resolve this annoying problem. >_<
Any help would surely be appreciated. Thanks!

Manually modprobe'ing usb-storage doesn't do anything. In fact, the module is not loaded at all, even if I manually modprobe it.

relevant lsmod output (notice that the usb-storage module is not loaded):

usbhid                 47648  0

hid                    52352  1 usbhid

relevant dmesg output:

Re: Unable to mount USB storage devices

The deregistering of an ubs device happens when disconnect it e.g.

Is the contact/cable is good ? Isn't there any contact error ? Do you use extension cable ? Does it work with a livecd, like ubuntu or sushe ?

In last case you can debug this usb driver with printk to the syslog. E.g. Why the deregistering function was called.

Re: Unable to mount USB storage devices

Yes, the contact is good (relatively new laptop and flash drive). I'm not using any extension cables. In fact, the device is still "visible" when you look at the lsusb outputs.

Re: Unable to mount USB storage devices

Has it worked before? Did it stop working after some update? Don't know if it helps but this is my modules line in rc.conf:

MOD_AUTOLOAD="yes"
MODULES=(acpi-cpufreq cpufreq_ondemand cpufreq_powersave b44 mii iwl4965 snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd snd-hda-intel soundcore hid_apple !net-pf-10 !pcspkr !snd_pcsp)

and lsmod | grep usb

usb_storage            64192  0 
usbhid                 47584  0

Re: Unable to mount USB storage devices

Yes it was working before. My /etc/rc.conf is fine.
The problem is that the usb-storage module fails to load in my system. I don't know why this is the case.
In your case, the usb-storage module is loaded. In my system, even a manual modprobe doesn't do anything.

Btw, here's the relevant lspci output:

00:1a.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 03)
00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 03)

this is what happens when a flash drive is plugged in (via udevadm):

Re: Unable to mount USB storage devices

I am actually having this same exact problem, except it ONLY occurs after plugging in an off-brand USB card reader/writer.  After that, all usb storage devices stop working AND I'm unable to rmmod usb-storage or halt the computer without holding down my power button.
