Bug Description

On my Canonical-Issued Toshiba Tecra A4, I plugged in a few various USB storage devices like thumb drives and even an iPod, and I get the following output on dmesg:

usb 5-3: new high speed USB device using ehci_hcd and address 2
ehci_hcd 0000:00:1d.7: Unlink after no-IRQ? Controller is probably using the wrong IRQ.
usb 5-3: device not accepting address 2, error -110
usb 5-3: new high speed USB device using ehci_hcd and address 3
usb 5-3: device not accepting address 3, error -110
usb 5-3: new high speed USB device using ehci_hcd and address 4

The drive fails to mount. I need this working so I can get some dmesg output for some other bug reports regarding network connectivity, which I am without due to problems with the sky2 driver.

I get this same error when I use a attache' 1GB memory stick within the live-cd desktop.

I resolved this by doing the following:

#1) Boot with pci=noacpi and irqpoll
#2) This will make your ethernet and USB drives work. You can then apt-get update and dist-upgrade to get the latest kernel.
#3) Restart, upgrade your BIOS to 1.70. This gets around a measure that forces pci=noacpi for BIOS version 1.60 which actually appears to make things worse.
#4) Restart, enjoy ethernet and USB.

I will post this on the Toshiba Tecra A4 page at http://wiki.ubuntu.com/LaptopTestingTeam/ToshibaTecraA4
