Summary: implement 100mA charging in Linux
Product: OpenMoko
Version: current svn head
Platform: Neo1973
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: kernel
AssignedTo: stefan at openmoko.org
ReportedBy: laforge at openmoko.org
CC: werner at openmoko.org
Linux should export two USB configuration descriptors that are completely
identical, with one difference: power consumption. The first config descriptor
should indicate 250 units (500mA), whereas the second one should indicate 50
units (100mA).
Please also note that we should verify that the 'self powered' flag in both
configurations is switched off.
Currently, we only export one descriptor with 500mA. This means that if you
attach your fully-booted Neo1973 to a bus-powered hub (such as the DebugBoard
v2), it will not enumerate on the USB [since the host cannot provde 500mA but
the device only exports one configuration with that high current].
