Fedora12 Slow USB 2.0 Write Speed, ehci_hcd module is missing

0

I am using Fedora 12, the problem I am facing is USB 2.0 write speed. I have a dual boot system with Windows XP and Fedora 12. USB 2.0 write speed in Windows XP is much faster then what I am getting in Fedora 12.

After searching Google I came to know that ehci_hcd module is missing/not present in my system. ehci_hcd module is neither loaded nor it is present in the available list of modules.

Can someone guide me how to fix this issue? Does ehci_hcd have something to do with USB 2.0 write speed?

Do I have to recompile the kernel and add/enable the ehci_hcd module?

By the way you should come to #Fedora channel on Freenode IRC network. Not like Superuser couldn't help but this is an answer editing pain always. Such problems are much easier to solve on IRC. Just a note/idea. – Apache – 2010-06-04T07:11:00.563

What do you mean by missing? What happens if you simply try to modprobe? Like:

su
modprobe ehci_hcd
?

Hmm. Try checking your bios. lsusb outputs whether you got a 2.0 capable hub or not. – Apache – 2010-06-04T07:51:42.597

lsusb output
