This can't work without a lot more effort.

altos/stmf0: Rework the sram allocation to save a few text bytes2016-06-12T05:16:12+00:00Keith Packardkeithp@keithp.com2016-06-12T05:16:12+00:00urn:sha1:1704d27248f1845c545ec61cf1bad58bf41189af
Boot loaders were going over 4096 bytes of ROM. I suspect we'll need
more serious work soon.

stmf0: Do not send more data than requested for GET_DESCRIPTOR2016-06-10T05:06:30+00:00Keith Packardkeithp@keithp.com2016-06-10T05:06:30+00:00urn:sha1:36ba97fabbed2f2a4a89da5be221c630ea3ff66f
When Linux boots, it asks for only the first 8 bytes of the device
descriptor; we must limit the amount of data sent back to that amount
or USB will get wedged.

stmf0: Clear all USB state when resetting chip. Wakeup all sleepers2016-06-10T05:05:24+00:00Keith Packardkeithp@keithp.com2016-06-10T05:05:24+00:00urn:sha1:2970de9f92243b11d3beef56f3b1df3ef3579b95
When USB is reset, but the board is not power cycled, all of the
internal USB state needs to be reset, and any tasks blocked on sending
or receiving packets need to be awoken so they can go wait for USB to
start running again.

altos/stmf0: Fix build without second USB IN endpoint2016-03-05T22:37:40+00:00Keith Packardkeithp@keithp.com2016-03-05T22:37:40+00:00urn:sha1:7cb388a33104fd78c8cb1fa08a6f114e3e1e372d
The code for the second IN endpoint was using the wrong ifdef.

altos/chaoskey: Add another USB endpoint to read raw data2016-03-02T21:59:21+00:00Keith Packardkeithp@keithp.com2016-03-02T21:54:58+00:00urn:sha1:05fcb717bfc44aba3c1cfd43281e323505a46402
This replaces having the single output switch based on a pin value and
allows us to box the device and still fetch raw data.
For now, this will use a special libusb2 program, ao-chaosread, to
pull bits as I haven't figure out how to make linux provide two
/dev entries for one USB device.

altos/stmf0: Use device ID as usb serial number if requested2016-02-15T23:24:35+00:00Keith Packardkeithp@keithp.com2016-02-15T23:24:35+00:00urn:sha1:5637c1b2fd7232842245af1437e33b5bb1583c7d
This exposes the hardware device ID (which is unique per-chip) as the
USB serial number, avoiding the need to create a custom ROM image for
each device.

altos: Allow USB drivers to skip CDC-ACM -specific descriptors2016-02-07T23:42:28+00:00Keith Packardkeithp@keithp.com2016-02-06T13:10:57+00:00urn:sha1:2ad756bd1b63a2c8450edd7001628b92279fd1b8
For devices not providing the standard CDC-ACM interface, let them
skip the various descriptors and interfaces to provide a more limited
set of capabilities.

Allow USB suspend to suspend USB, GPIOs and master clock.

altos/stmf0: Allocate USB buffers at startup2015-03-01T00:10:10+00:00Keith Packardkeithp@keithp.com2015-03-01T00:00:45+00:00urn:sha1:476c5b87ea0901f70fe98b581ecca9afaf957607
This lets the extra allocations used from ao_usb_alloc_buffers be
allocated before the first USB connection happens.
