Roger,
The MCF5328, MCF53281, MCF5329 processors are all supported in kernels
greater than 2.6.21. Freescale's LTIB Kernel release is not in sync
with the public kernel. I understand that Freescale has both an OTG and
host USB driver written but their released patched for the OTG and the
patches for the host mode USB were not accepted by the Kernel USB
maintainers. The uClinux-dist kernel release based on 2.6.21 we have
used at Arcturus Networks for our uC532x modules does support USB thumb
drives. The patches we have tested from Freescale for USB in the newer
kernel versions extended support for mice, keyboards and other misc bits.
