New feature of the Windows 8.1 (native) upgraded drivers:

http://msdn.microsoft.com/en-us/library/windows/hardware/dn303354%28v=vs.85%29.aspx#usb_wdk

Maybe this was mentioned elsewhere, but I don't remember seeing it.

Also confirmed from my 8.0 and 8.1 platforms: the 8.1 version of 
winusb.dll (v6.3.9600.16386 dated 2013.08.22) has the WinUSB isoc 
symbols, whereas the 8.0 version of winusb.dll (v6.2.9200.16384 dated 
2012.07.26) doesn't.

While I was at it, I downloaded WDK 8.1 
(http://msdn.microsoft.com/en-US/windows/hardware/gg454513#drivers) to 
see if the WinUSB redistributables had been updated in any way, and lo 
and behold, what's provided there is still the obsolete crap from 2006: 
just open one of the the winusbcoinstaller DLL with 7-zip and have a 
look at the winusb sys|dll.

With Microsoft not helping in the slightest, I have no idea how I'm 
gonna go around providing an updated version of the drivers in Zadig, 
that support ISOC, for Win7 users, as, regardless of what Microsoft 
chooses, this'll probably be a much desired feature. By the looks of it, 
we may have to repackage the coinstaller DLLs in an unofficial manner or 
something...

Unfortunately, it's also become quite obvious that I have no choice but 
to drastically cut on the amount of development I invest in 
libusb/libusbx. So, just to make that clear, don't expect any WinUSB 
ISOC implementation from me for the Windows backend - Unless I can ditch 
my day job, it'll will have to come from somebody else.

Same goes for USB-3 bulk streams (for what is worth, I'm not even going 
to bother trying to look at it) or any new Windows backend related 
development for that matter.


Now, while we're on the subject, some of you may remember that some time 
ago, we also inquired about the device Microsoft used to test their USB 
3.0 stack. Well, that device, which is called "Super MUTT" and 
unsurprisingly revolves around an EZ USB FX3 controller, is available 
for purchase from JJG Technologies:
http://jjgtechnologies.com/mutt.htm

I'm currently trying to play with the available downloads from the site 
to see if I can convert the FX3 device I have into a SuperMUTT. Not sure 
if this is going to work as the SuperMUTT device appears to have a 2MB 
EEPROM, whereas the FX3 kit has a smaller one.
