| Jun 29, 2012 at 22:30 | comment | added | tcrosley | Since a 2.0 USB Host is expected to provide power (either 500 ma or 100 ma, depending on the request from the peripheral during enumeration), then supplying power in the reverse direction while acting as a host wouldn't seem possible, unless some non-standard circuitry was available, which I doubt you could count on being in every Android device. | |
| Jun 29, 2012 at 3:24 | comment | added | Chris Stratton | Ironically, in some of the devices where USB host mode is not officially supported (especially phones) but has been enabled by owner-installed kernel changes, its often been the case (at least initially) that the charge pump to drive 5v out the USB port was either non-existent, or not being enabled. In those cases, you probably could do at least a USB-current-limit charge - and you nearly had to, as you had to provide an external source of USB bus power for the use of the peripheral. | |
