there were some Bizarre things going on regarding small driver updates with CC121 also. they upload new driver with no mention then it disappeared and so on…
anyway i reverted to Mixed MR1.7.5 tools with newest FW driver… i had problems with “Device not found” messages after some time MR was turned on on WIN7.
But if i’m not mistaken i think steinberg did mention about 1.76 update on the news column.
im not sure untill now if it was the problem cuz i did some physical cleaning to FW ports on MR and Computer, but anyway its fine now so im with the older driver which anyway work well with Win7
