Fedora 3: Can't see usb devices all of a sudden!

[bradmatic]

Hello all,

I am using kernel 2.6.11-0.3.rdt.rhfc3.ccrma (a low-latency kernel from Planet CCRMA) for Fedora Core 3. I shut down my computer last Friday as I was going out of town for the weekend with everything working completely fine. I came back today and rebooted it, and now none of my USB devices work. I don't believe it's a USB problem per se, as my USB printer works fine and "/sbin/lsusb" gives the following (which doesn't seem unusual):

Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 03f0:0604 Hewlett-Packard DeskJet 840c
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000


The error I get when trying to mount mass-storage USB devices is "mount: special device /dev/sdx does not exist" -- it seems like a problem with SCSI (I guess). I had devices sda1 and sbd1 in my /dev diretory before I left, but they are no longer there. Does anyone have any suggestions as to what may be going on here??

Thanks

have these devices plugged in before the system boots and theoretically it should detect them.
