Boot from USB hard drive problem

["Serguei I. Ivantsov" <manowar@xxxxxxxxxxxxxxxx>]

Hi!

I have a problem booting from hard drive connected to USB-PATA IDE
bridge integrated onto the motherboard.

I have enabled all (?) USB and SCSI-related stuff in linux kernel.
When booting, kernel detects USB controllers, hubs and even USB-PATA IDE
bridge, but does not detect hard drive attached. It seems usb mass
storage driver does not even try to scan/probe devices while initializing?


Linux kernel 2.6.20.4 /x86-64
