usb_cdcacm: Make USB lib globals weak symbols.

2013-01-18T23:18:30+00:00

This allows users to override them. Signed-off-by: Marti Bolivar

usb_cdcacm.c: Fixups for usb_cdcacm_tx().

2013-01-17T23:08:39+00:00

- Check if we're transmitting (instead of how many bytes are left untransmitted) before bailing, in case we're transmitting a zero-length packet. - Set transmitting=1 before setting the endpoint valid to avoid races with the USB interrupt. - Eliminate some duplicated code.

Handle sending 0 byte packets.

2013-01-17T20:17:00+00:00

Added a flag to see if we are currently waiting on an interrupt to acknowledge the sending of the current IN packet. Added a method usb_cdcacm_is_transmitting() to check for that flag. Signed-off-by: Manuel Odendahl

Move endpoint definitions to include files (they are now needed outside in usb_serial.cpp)

usb_cdcacm.c: reenable the endpoint if an empty bulk transfer was received.

2012-11-08T19:53:32+00:00

It is possible to receive empty bulk transfers. This would lead to the endpoint never being reenabled as this was handled by the read routine. This caused the USB to hang. Signed-off-by: Manuel Odendahl

usb_cdcacm.c: Fix up descriptor definitions.

Move contents of usb_descriptors.h to .

2012-08-04T22:43:46+00:00

These form and name of structs etc. is basically determined by the USB spec and the libmaple style guide, so there's little reason for them to change, and less reason for them to stay hidden. Signed-off-by: Marti Bolivar

Prep usb_descriptors.h for removal.

2012-08-04T22:43:45+00:00

Just change names and things to fit the libmaple style. Its contents will move to the top-level header next. This API is still unstable, but we need to expose pieces of it in order to get the Maple-specific pieces of usb_cdcacm.c into Wirish. Adjust uses of the API appropriately.

usb_cdcacm: Remove unused/redundant variables.

usb_cdcacm: Expose line coding state.

2012-08-04T05:47:22+00:00

This was already supported, so just move the line coding structure to the header and add some functions for accessing the current values. Signed-off-by: Marti Bolivar
