ChangeSet 1.1722.97.70, 2004/06/11 17:06:39-07:00, [EMAIL PROTECTED]
[PATCH] USB: usb on big endian, ehci needs a byteswap
Adds a missing byteswap that would affect interrupt transfers
with EHCI on big-endian platforms, like Rick's MIPS-4km uClinux.
Needed for external hubs, and then likely for mice, keyboards,
and so on.
