Re: [libusb] windows isochronous transfer

[Accio <ac...@ya...>]

Can you give me some more details about using UsbDk?

I've:

- compiled and installed (MinGW) the libusb enabling usbdk (--enable-usbdk)

- installed the official usbdk msi

- executed UsbDkController -i to install usbdk driver

After this my application no longer gives "unsupported" error but after 
a while freezes the system (I need to restart by power button) giving no 
errors.


There's some passage I've missed?

There's something I can try?
