 Though #7620 fix loads ohci-hcd driver, booting from USB produces
 filesystem errors, and boot never completes. This happens because ehci-hcd
 driver is not loaded before the USB drive is mounted. Likely the problem
 did not happen with early firmware that prevented EHCI from working.

 Adding the line
 {{{
 call(['/sbin/modprobe','ehci-hcd'])
 }}}

 after
 {{{
 call(['/sbin/modprobe','ohci-hcd'])
 }}}

 in initutil.py (exact position in the file varies between versions)
 loads both drivers before mounting USB drive, fixing the problem.
