[Bug 88746] Re: ehci_hcd module causes I/O errors in USB 2.0 devices

[Hated On Mostly]

Testing a possible temporary solution. Try it if you are brave, although
no problems experienced for me.

Try replacing the file "ehci_hcd.ko" which is located in

/lib/modules/<kernel version number>-generic/kernel/drivers/usb/host

With the same file from a kernel version that USB transfers work just
fine for you.


For example, I replaced my file on the current system with the "ehci_hcd.ko" file from the live CD of Ubuntu v8.04.1, which I found in the following location:

/lib/modules/2.6.24-19-generic/kernel/drivers/usb/host

I am in the middle of preliminary testing, but so far it seems to have
fixed the problem for me using kernel 2.6.27-10. It seems to be giving
me the same performance I get from the live CD in which transfers work
just fine. Will report back later, hopefully someone else with this
problem will try it out and let us know his/her experience.
