ok, ok, I'm stupid, after write the comment, i search more info and find this:
http://www.linux-usb.org/FAQ.html#ts6
Q:  Why doesn't USB work at all? I get "device not accepting address".
A: This can be one of several problems:
    * High speed devices sometimes have problems with cables used to
connect them. They're more sensitive to signal quality issues than
older usb 1.1 full or low speed devices. If the device works OK at full
speed on the same system, after you "rmmod ehci-hcd", this is likely
the problem you're seeing. There are a lot of things you can do to
change signal quality........ [cont]
with this simple test  "rmmod ehci-hcd" my pendrive USB work fine!!!
ok, good luck for all, and look the FAQ ;)
PD: sorry for my english (i'm spanish speaker)

Thanks
for the advice. I will try this but I'm not sure this is the problem
because *all* of my USB devices do not work so I know its not a problem
with the cable quality. It may be a hardware bus problem but when I
tried the 686 kernel instead of the k7 kernel, the errors do not occur
and all my USB devices work fine.

USB worked fine in 2.6.15-25-386 but no longer int 2.6.15-26-386 and edgy 2.6.17-7-386.
"rmmod ehci_hcd" does allow USB devices to work at 1.1 speeds.
This appears to be a duplicate of
bug #24925

Confirming
as well. I believe it is a problem with the BIOS in my case as I cannot
mount 2 different USB devices in WinXP (Dual boot, no I never really
use XP) and these work fine on my other Edgy system. One is a 80GB hard
drive usb and the other is a ATI remote wonder. WinXP sees them right
off the bat and says they are 'MALFUNTIONING' and to replace them. The
device name usually pops up, doesn't get the name though....
System is GigaByte GA-M55plus-S3G (F6 BIOS)
Athlon 64x2 4200+ (32bit Edgy)
Integrated Geforce6100
NForce 430
I believe the 6100/430 part is the important one as my 'google'
research shows this problem all over with 6100/6150 on ASUS boards as
well.
Things I tried:
modprobe -r ehci_usb
Change usb 2.0 to 1.1 in bios (Changed error messages)
Found F7 BIOS update (12/21/06 release)
Booting with the irqpoll noapic nolapic acpi=off options (In various
combos and created a keyboard that doubles everything i type.

Found
out it's probably an internal cabling problem (maybe noise interference
going to the front or faulty ports) Plugged my usb thumbdrive into the
rear port and it now works.
My suggestion is if nothing else works, try something simple like this.

Changing
ports and devices does not work. It happens with all of them. On the
other hand, I did notice that this only happens when my iPod is plugged
in on boot. I've tried different cables with the same problem and it
happens on any port. There is no problem if I simply boot without my
iPod.

      Mobo USB ports work after BIOS update
      (permalink)
   
  
  
   
   
   
My
problem was bypassed by updating BIOS and using USB ports on the
motherboard. At least the USB drive was automatically mounted after
that.
I had the "not accepting address: error" on both freshly installed
Gutsy and a previous Ubuntu release. Probably all Ubuntus after some
kernel version were affected. I also have seen this same problem on
other computers. Before finding a bypass, I had tried many solutions
proposed in this bug and many similar USB mounting bugs in Launchpad.
To bypass the problem
0) Prequisites: I had Ubuntu 7.10 Desktop amd64, motherboard Intel
Guardfish dq695gf with BIOS 5773. Problem: USB key is not mounted when
connected, but it prints some lines to syslog and dmesg.
1) BIOS Update: Downloaded latest BIOS update 6002 CO6002P.ISO from
Intel, burned to CD. USB related updates were mentioned in BIOS release
notes. Updated BIOS. Booted.
2) Mobo ports: Connected USB stick to motherboard USB port on the back of the computer.
3) Success: Rythmbox "Music Player" automatically started. I could play
music from the USB stick. Thus, the problem was bypassed.
4) Side effects: Front USB ports don't work at all anymore, and no
lines are printed to dmesg or syslog when USB stick is connected. USB
lights are not lit when connected to front USB ports.

I have this issue on a Dell Inspiron 5100 with latest BIOS.
It has two high-speed usb ports. Until recently I operated with a
single external USB disk in one of the ports, which works fine.
I tried adding an extra usb disk but it fails with the same message. The first usb disk continues to work, however.
I have attached my dmesg output.

I am still using "sudo modprobe -r ehci_hcd" in order to use my USB flash drives.
from my dmesg:
======================================
[15571.551295] usb 1-2: new high speed USB device using ehci_hcd and address 3
[15581.914390] usb 1-2: device not accepting address 3, error -110

[15606.471610] usb 1-2: device not accepting address 6, error -110
======================================
also recently updated my BIOS to the latest version.
also get this message shortly after each bootup.  Wonder if it's related:
======================================
[  292.819263] irq 7: nobody cared (try booting with the "irqpoll" option)
======================================
I haven't used "irqpoll" but from what I've read it is used when a
system is really broken. However, I do use "noapic" as a boot option.
Just wondering why this bug still exists as I have seen reports back to 05?  I'd like to see USB2.0 speeds again...
