In general I myself are not supportive of USB device bluntly violating
USB specifications. And I think non-compliant device like AVR
FW Based USB device should not be forgotten already since there
are many cheap USB device readily available now.

Ref: I said the following at that time (more than five year ago).
"There is a hack to get libusb-win32 to work with such device
(to replace bulk with interrupt transfer in the driver level)
but it is much better that you change the firmware to
be compliant with the USB specifications.

Ref: http://www.recursion.jp/avrcdc/"

The avrcdc page now said
"The back door to the low-speed bulk transfer is gradually
closing on the newer OS. After enjoying this USB technology,
switch to the HID protocol or to MCU having on-chip USB
controller."
