Thank you all for your thoughts about the USB disk problems I'm having. I follow-up below.

Yes. > What do you get from lsusb, both plugged in and not? No difference, a list of the other USB devices. sp113438 asked if I tried usbmount. I believe usbmount and pmount are both wrappers for regular users to mount removable drives. I use pmount and it cannot mount anything because the kernel doesn't see the drive. I tried to mount the device it should be, but as expected, the kernel said it couldn't find that device.

Then once the system is up, manually modprobe uhci-hcd. On my system, uhci-hcd wasn't loaded, only ehci-hcd. I tried this on one system today and when I insmod'ed uhci-hcd without ehci_hcd, I received a message that ehci_hcd has to be loaded first, and it was loaded automatically. Jude mentioned updating the usb-ids, but as another poster said, I think that just updates the information about devices, not the drivers.

Is the disk > self-powered (with its own power adapter) or bus-powered ? The external drive in question has its own power supply. Since it works on the other computers, I assume it is getting enough power, but the laptop it isn't working on is the newest. I suppose it is possible that the newer X201 has a more sensitive USB hardware system. I have since copied the stuff I wanted to put on the drive via rsync across machines, rather than using one computer with two external drives. I suspect the drive is the problem and that the older machines are less picky about everything working right. Thank you again!
