[pvrusb2] Module ehci-hcd may prevent pvrusb2 reconnect

[roger]

Found a bug, if the pvrusb2 device is disconnected via power cable and
then plugged back in with the ehci-hcd module still loaded, the device
may fail initializing and the system logger will only show:

Mar 27 19:59:07 pvrusb2: unregistered device video0 [mpeg]
Mar 27 19:59:07 pvrusb2: unregistered device radio0 [mpeg]
Mar 27 19:59:07 msp3400 1-0040: chip reset failed

Or, you may only get a one or two line notice stating the pvrusb2 has
been plugged in (with no device initialization).


A work around, compile ehci-hcd as module and manually reload
(rmmd/modprobe) the ehci-hcd module.  Unloading the pvrusb2 module or
any of it's dependents (msp3400) doesn't seem to be need for the pvrusb2
to initialize.  Matter of fact, just removing the ehci-hcd module (ie.
rmmod ehci-hcd) without even loading the ehci-hcd module will
automatically allow the pvrusb2 device to initialize.

This may have been a long standing issue for the past year or more.
