welcome! From what I have read, there are three camps:

1) USB host is impossible on the n900
2) USB host might be possible via software/register modification, but the hardware won't supply enough power or work correctly.
3)USB host might be possible via software/register modification, and it will work like the n810.

Best case is the last one, the second case will probably need a power injector or something. The first case means no-go. No one really knows until it ships and the hackers here start working on it.
