| May 6, 2014 at 14:29 | comment | added | Passerby | By working on the proven through experience knowledge that usb power management is mostly an honor system, for the host and peripheral. 90% of hosts provide power without any current limiting at all. And while there isn't any data being sent by the ftdi, there is still usb communication every keepalive polling period. So KISS, don't over engineer. | |
