Hi, since some versions of the 2.6.x kernels I have a problem w/ an usb stick. After googling around for "device not accepting address 4, error -71"-errors, disabling acpi, using old_scheme_first=0/1 etc. pp. and trying different 2.6.11.x-2.6.12.x kernels I installed yesterday 2.6.13 w/ CONFIG_USB_STORAGE_DEBUG=y and connected the stick to a usb port:
