joerg, remember the ID pin IS hardwired to twl4030 and it can be sensed. a piece of code ( hostmode daemon ) can be written to sense this id pin and switch automatically to host. even now n900 switch to a_idle when ID pin go ground so what must be put into the code ?
because some peripheral need external power it is possible to make a custom y cable like this

uB female ---o---------> uB male (with id grounded )
A female -----|

it is not standard compliant but who care
this cable can be used with or without external power provided from standard n900 charger
i will hardmod my n900 with uAB receptacle as soon i will get one for ( stylish ? ) CA-157.

( ot - please respond to my last PM it is @bme )
