Comment 1 Alan Stern 2007-05-29 14:56:50 UTC

Problems like this are very difficult to handle without extra debugging
information.  In this case it would help to see either a log recorded with
CONFIG_USB_STORAGE_DEBUG turned on or a usbmon trace (see
Documentation/usb/usbmon.txt in the kernel source).  Can you provide one or the
other?

Comment 2 Joachim Beckers 2007-05-30 01:36:10 UTC

I'm having the same problem, with 2.6.20 and 2.6.22. I also had it in the past
with various 2.6.x kernels.

I'll see if I can provide the needed logs.

"it would help to see either a log recorded with
CONFIG_USB_STORAGE_DEBUG turned on or a usbmon trace (see
Documentation/usb/usbmon.txt in the kernel source).  Can you provide one or the
other?"

I tried rebuilding the kernel with CONFIG_USB_STORAGE_DEBUG turned on using a combination of these two guides:

https://wiki.ubuntu.com/KernelCustomBuild
http://ubuntuforums.org/showthread.php?t=311158

The new kernel would boot but no USB devices were recognized. Could anyone walk me through this?

Comment 5 Alan Stern 2007-09-19 08:27:03 UTC

Make sure you have all the necessary drivers built into the kernel or loaded as modules.  You'll need usbcore, ehci_hcd, usb_storage, scsi_mod, and sd_mod at a minimum.
