I didn't find anywhere which clocks does Cyan2 use? Looks like clocks are generated from USB/I2S inputs via FPGA, ie it doesn't have any physical internal clocks at all? Can someone please explain?

There are questions already above about different codes shown in driver, phase light on after reflush and power cycling, different operating systems by different people,etc... Not to fantasize further I guess we'd better call @alvin1118 now to clear it all together)

No errors, exept that I couldn't see the device in upgrade mode 'till I installed the config driver. I don't use windows, so I don't know the previous numbers.

Which code should it display when upgrade is correct? Mine shows V3.12|A22E1.6 Is that correct?

Nice USB cable... Is there any evidence (marking) on the power part of this cable btw? One might need to interrupt the vbus (red) and connect the cleaner supply (ex psu or battery)... this tweak can enhance the SQ very much!
