Hi all. I'm a newbie to Fedora, though I've been playing with Mandrake a while now.

About the only thing I had problems with in my move to Fedora (and the goodness that is Gnome 2.6) was the fact that FC 2 is the only one of the newer distros that didn't support my Sandisk USB drive out of the box.

A little experimentation showed me that actually it wasn't a mounting problem, but rather a problem of the device literally not being seen by the OS. A post I found mentioned that a module loading in FC2 would stop the USB ports on my ASUS A7N8X Deluxe motherboard from reporting the USB flashdrive.

I've found that commenting out the line "alias usb-controller ehci-hcd" would allow the system to see the drive properly, and allow it to be mounted. Everything now is working just peachy.

My question is, is commenting out that line possibly harming my performance in some other part of my system? I think all it does is provide USB 2.0 support, but I just wanted to verify that. USB 1.1 support is plenty good enough on a 128 mb device. Especially when the alternative is not having the use of it at all ;) My only other USB device is an Intellimouse.

Here's what my modprobe.conf now looks like:


alias eth0 3c59x
alias snd-card-0 snd-intel8x0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
#alias usb-controller ehci-hcd
alias usb-controller1 ohci-hcd
alias char-major-195* nvidia

I believe you are correct about that driver. The full name is USB 2.0 'Enhanced' Host Controller (EHCI) Driver If all it does is remove 2.0 support, it should just limit the transfer speed. If you don't have USB hard drives I don't think this will be an issue.
