Hi,
On 2.4.13 release, i planed to update my kernel from 2.4.6 to 2.4.13 on
my Debian.woody.
But, after compiling an testing my usb-storage won=B4t work.=20

I searched the web and found a posting in this Kernel-List wich
described this Problem (Okt/2001) without a solving suggestion.
I tried with the new 2.4.15-pre4, but it won=B4t work with this Version
too.
Now im using 2.4.8, in which it works fine.
I took the old configs from 2.4.6 with "make oldconfig" to it,
so the fault shouldn=B4t be my  Kernel-Configuration.

Some Infos:
my Hardware:
Siemens PII-600 Lifebook S4546
Debian woody
DataFab MD2-USB 2,5" IDE Disk on Usb,=20
info on Kernel 2.4.8:

Please let me know if there are any further logs, configs you need for info?
