When i plug in an usb-storage device (it's a 2 GB USB 2.0 mp3 player), the device can't be loaded by the kernel anymore. To except a hardware issue i tried it on several machines: The device works on my laptop with kernel 2.6.22, on my old 2.6.13 workstation and even on my ps3 with kernel 2.6.23. But it doesn't work using 2.6.24. I will attach more detailed informations about the used kernel versions and the dmesg outputs. I know this bug will be hard to fix... let me know if i can do anything to support you. It seems that this kind of failure is more common since a friend told me that he has nearly the same problem with an usb printer. Reproducible: Always

Can you attach the output of lsusb -v for that particular device? Also, did it work on 2.6.23? What was the last working kernel before the 2.6.24.X version. lsusb is provided by: sys-apps/usbutils
Created attachment 144151 [details] lsusb -v of the device Here is the output of lsusb -v of the device (I saved the output using 2.6.22 because the device doesn't appear on 2.6.24). Now I will compile a 2.6.23 kernel on my system and give you feedback about the last working kernel version after that.
The last working kernel version is gentoo-sources-2.6.22-r10; gentoo-sources-2.6.23 doesn't work. Additionally I tried it on my ps3 using the latest ps3-sources-2.6.24 from the cell overlay and it worked there. So it seems to be an architecture specific problem. I also found out something interresting: The usb-storage device works with gentoo-sources-2.6.24-r2 (and probably with 2.6.23) when it was plugged in before boot. But when I plug it in after booting the system, it doesn't. This is reproducable. I will attach a full 2.6.24 dmesg output when i plugged it in before boot.

Can you attach a dmesg with CONFIG_USB_DEBUG and CONFIG_USB_STORAGE_DEBUG turned on.
Created attachment 144636 [details] dmesg output with usb debugging enabled Here is the result :) You can find the output after pluggin in the device at the end of the logfile (plugged in to usb 1-6) Do you also need the same of a working kernel?
Is ehci_hcd compiled as a module?
No, it isn't.
Some people have reported sucess by trying the following: after building ehci_hcd as a module and rebooting: Remove the device modprobe -r ehci_hcd plug in the device Does it work? Does the module show up in lsmod, if not what happens if you modprobe ehci_hcd. If the above steps work, it might be a timing issue.

Created attachment 145845 [details] dmesg output ehci_hcd compiled as module In order to improove the readability I inserted lines like "--- MARKER: Removing the device and the ehci_hcd module ---" between each of the above steps. So search for "MARKER" :)
Can you try something else: Remove the device modprobe -r ehci_hcd echo Y > /sys/module/usbcore/parameters/old_scheme_first plug in the device
Currently I'm using a kernel with usb compiled in so i didn't removed any module. But.... great, it works!
