Does the STMF103 USB support a promiscuous mode?

Hey,

I want to implement a �smart USB hub� (in software) which will include multiple devices, not a single compound device. Currently I can set the device address with the relevant register and get only the transactions relevant for that address, but I want to receive all transactions and then decide, in software, if I need to respond to it or not. My application may add or remove devices from this smart hub in runtime so a USB hub IC will not do.

Thanks in advance,

Assaf
