I have created a bootable USB stick (USB2/4GB) using the instructions at http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows. Using 12.0.4 on 32bit laptop.

All seems to work, no errors. But when I then boot from this on a laptop, I get the Ubuntu logo, lots of output and then errors such as 

usb 1-3: device descriptor read/64, error -110
reset high-speed USB device number 3 using ehci-pci
device not accepting address , error -110

and finally unable to enumerate USB device on port 1 After this I can press enter and get a initramfs shell. I can then shutdown using a long press on power button. The shutdown command is not part of this shell.

So I am guessing that the stick is working otherwise I would not get this far though there may be corruption in the files(?). No other usb ports being used though touchpad/keyboard may be usb.

I have googled this and the only answer seems to be shutting down, removing the power cord (and in my case the battery) for 5 minutes and trying again. This has not worked.

I did get this working a few years back with the same USB stick (since reformatted) on a different laptop. This laptop is a thinkpad T61. Any ideas what I have done wrong?

Just to add the first line of output where it starts to go wrong is [initramfs] Unable to find a medium containing a live file system

Just compared checksum with what I downloaded and they are the same. I downloaded ubuntu-12.04.3-desktop-i386.iso

So I downloaded 13.04 and that worked fine. So the problem is 12.04.3 which I have to say is pretty poor. Perhaps it is my PC - a thinkpad so hardly a noname machine - but not impressed. Especially as others have raised this too.
