hello all, i am also experiencing the same issue, when i use shift keys the keyboard dies entirely. it is intermittent as i've just realized, because after suffering from the error last few days it's working now
<TEST???>
without disconnecting the keyboard, i opened the device manager, uninstalled the 2 keyboard drivers, and hit scan for system changes, which reinstalls the keyboard drivers, keys a-z work fine until i hit shift, then the whole keyboard becomes dysfunctional. it has been highly repeatable error.
I was quite surprised that it worked for just now this time as i needed to register to this forum and produced an @ symbol with shift 2 key... 1st time it's worked.
I believe this is a software issue!
i'm running win 10 which is upto date, as it updated just the other day.
Please advise.
