Since upgrade, USB Drives won't stay mounted

[Keleigh3000]

Since upgrading from Feisty to Gutsy, my USB drives (both external IDE and thumb drives) have developed the annoying habit of unmounting themselves at seemingly random times. This is quite annoying. Is there anyway to get them to stay mounted indefinitely until I either unmount them manually or remove them?

Not that I've found. I'm still running Feisty. The problem isn't related to Gutsy itself, but, I believe, to KDE 3.5.8. When I was running KDE 3.5.6 and 3.5.7, my USB drives always appeared on my desktop. When I upgraded KDE to 3.5.8, this stopped.

Hmm... You mean they actually unmount themselves and don't appear to be connected any more?
If you go into media:/ (in Konqueror) do they appear? How about if you execute "lsusb"?

When this happens, the icons usually still appear on the desktop, and in /media, but the little green arrow that indicates that they are mounted is gone. If I right click on them, there is now a mount command on the context menu that isn't there otherwise, and it will work. If an application tries to access the disc, I'm told it's not accessible. If I click on the icon, either on the desktop or in /media. it will mount and open in Dolphin. Here's the output of lsusb with all devices mounted:

#009 is my Creative Zen player, #008 is a thumb drive, and #002 and #003 are external IDE hard drive enclosures. A little while ago, I noticed that all but one of the external drives are unmounted. Here is lsusb now:

This sounds similar to a problem I've been having. The best workaround (can't really call it a "solution" per se) is to run

sudo modprobe -r ehci_hcd

from the console.

CAUTION: This knocks your transfer speed WAY down; all your USB 2.0 devices now look like USB 1.1. On the other hand, said devices stay mounted and don't disappear off the face of the earth.
Good luck and let us know what happens.
