56162d0105 Remove BCD.Int, add BCD.Major/Minor. Remove USB spec versions 
- I don't expect them to get much use, and reuse of BCD for USB spec
version and device revision makes it somewhat confusing.

f668df87df OpenEndpoint for now takes an address - a device can have two endpoints 
with the same number...

13f4e95f2f Unexport bitmasks, they are only used internally. All values present 
in exported structs are meaningful and the users should not need to use
bitmasks.

168b501d53 Rename IfClass/IfSubClass/IfProtocol to Class/SubClass/Protocol, these 
fields occur within an interface descriptor.

ca02c03241 since this is the only usecase, return a *libusbDevice for a new 
pointer.

3ec748db4c An invalid pointer triggers a runtime failure when passed as argument in 
Go1.7:
runtime: bad pointer in frame
github.com/kylelemons/gousb/usb.(*fakeLibusb).open at 0xc420045ce0: 0x1
fatal error: invalid stack pointer

Use an arbitrary C-allocated pointer instead.

e0f30623b3 Modify EndpointInfo to provide meaningful data rather than raw USB 
descriptor values. E.g. for the user, the distinction between
MaxIsoPkt and MaxPktSize is irrelevant, only the calculated max packet
size matters.

4b17678362 remove a call to libusb_open_device_with_vid_pid, as it's just a 
convenience wrapper. Reimplement the same trivial wrapper in Go.

00dbfd23dd done channel is now initialized on submit.
