I just saw in the errata that you do not advise using v2 100LX chip for USB
host application. We only have v2 chips on our dev boards (that is according
to cat /proc/cpuinfo) so I will wait a bit for us to get the v3 chips and
then - if they still wont work - I will try to debug it.
P.S. Just to be sure: Could somebody please confirm that we are using v2
version of the chip. They are marked: Etrax 100LX MCM 2+8 part number 18896.
