After some test I see that haldaemon spin up JAZ drive.
I have two USB pen drives, one is 32MB USB 1.1, second is 512MB USB 2.0.

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
This bug is already fixed in previous kernels, I think 2.6.11. BTW, kernel-2.6.12-1.1372_FC3 failed to boot on this machine (kernel panic), but this is another story.
