It appears not:
colorhug: Sending cmd 'SetLeds' args '00 00 00 00'
icoms: About to return usb write 5 bytes, ICOM err 0x0
colorhug: ICOM err 0x0
colorhug: Reading response
icoms: About to return usb read 0 bytes, ICOM err 0x100
Instrument initialisation failed with 'Communication protocol
breakdown' (Unknown error code)!
And it works fine with any 1.1.x firmware. You can test this by doing:
wget http://hughski.com/downloads/colorhug/firmware/colorhug-1.1.8.bin
colorhug-cmd flash-firmware colorhug-1.1.8.bin
-- This is the latest released firmware that does the incomplete
writes that does not work on Windows.
wget http://hughski.com/downloads/colorhug/firmware/colorhug-1.2.0.bin
colorhug-cmd flash-firmware colorhug-1.2.0.bin
-- This is the latest *test* firmware that returns the full 64 byte
buffer which fixes it on Windows.
