2019-06-17	usb_request: Fix some decoding errors	Stefan Brüns
	Append OUT data only if it has been ACKed. OUT transfers (BULK OUT or CONTROL transfer DATA stage) are typically NACKed to create backpressure. Always keep IN and OUT transfers separate. On the physical layer, the endpoint number only uses 4 bits, and IN and OUT use separate tokens. In case the transfer is an IN transfer, set the high bit as used in the endpoint descriptors (i.e. 0x81 is IN enpoint 1, 0x01 is OUT endpoint 1).

2019-03-15	decoders: Add/update tags for each PD.	Uwe Hermann

2018-01-28	graycode, morse, pwm, usb_request, wiegand: cope with absent sample rate	Gerhard Sittig
	Improve robustness of some more protocol decoders. Few of them never checked for the availability of a sample rate in the first place, others checked for the presence of a spec but would not cope with a value of 0. Some checked the value only after processing it, which could result in runtime errors. This change is motivated by bug #1118.
2017-12-22	all decoders: introduce a reset() method	Gerhard Sittig
	Move initialization code of protocol decoders from the constructor to a new reset() helper method. The libsigrokdecode backend could run this method several times to clear the decoder's internal state, before new data from another acquisition gets fed to decode() calls.
2017-07-22	usb_request: Remove code duplication, save end sample in central location	Stefan Brüns

2017-07-22	usb_request: Handle CONTROL transfer protocol stalls	Stefan Brüns
	According to the USB 2.0 spec, 8.5.3.4, a protocol stall condition lasts until the next SETUP transfer. On reception of the SETUP, adjust the end sample accordingly, and flush the previous CONTROL transfer.
2017-06-16	Mark all stacked decoders as being PD API version 3.	Uwe Hermann
	This is not really relevant for stacked PDs currently (they can be used unmodified with either PDv2 or PDv3 low-level decoders), but it'll allow us to drop PDv2 support completely.
2017-01-07	license: remove FSF postal address from boiler plate license text	Gerhard Sittig
	Remove the FSF postal address as it might change (it did in the past). Reference the gnu.org website instead which is more stable.
2016-09-24	usb_request: Use "is" or "is not" with None.	Uwe Hermann

2016-05-26	Consistency renames of {ss,es}_ variables.	Uwe Hermann

2016-05-11	usb_request: Drop hardcoded samplerate.	Uwe Hermann
	The libsigrokdecode backend now passes metadata (e.g. samplerate) to all PDs, stacked and non-stacked (see bug #664), so this interim solution is no longer needed.
2015-12-24	Use self.out_binary naming consistently across all PDs.	Uwe Hermann

2015-12-24	Use a Python list (not tuple) for OUT_BINARY.	Uwe Hermann
	This is more consistent with annotation syntax and looks slightly better in most cases.
2015-12-04	usb*: Minor cosmetics.	Uwe Hermann

2015-12-01	usb_{packet,request}: handle PREamble transmissions	Stefan Brüns

2015-11-30	usb_request: Handle transmission timeouts	Stefan Brüns
	If a device or host did not receive a handshake 18 bit times after the EOP, there was a transmission error and the host may repeat the transmission
2015-10-06	usb_request: USB transaction decoder and PCAP generator	Stefan Brüns
	The new decoder stacks on top of the usb_packet PD. It adds one new annotation row, and is able to save the decoded data as PCAP trace. It has been successfully tested against all traces in sigrok-dumps and some more traces.
