In general most controllers do have some limit on the amount of data
they can transfer at once.

For some you can apply workaround at controller driver level and for
some it's not practical.

Also for some the limit is lower so it is more likely hit.

I guess you can call controllers that have both of these limitations
crappy but that's what's in the silicone out there.

If you have better solution to the problem please share it in detail.

Thanks

Michal
