[PD] comport rxerrors on W10

Microsoft has completely rewritten usbser.sys

maybe there's some meaningful info

a bit off topic

(beside the comport errors) i have also a lot of problems in W10 to  
get Pd, Vanilla & extended, to work as i was used to.

i cannot trace it back, but one of the things i did was to clean the  
windows register manually from every entry related to Pd, Pd-extended  
& PureData.

another cause seems to be the use of 'deken';
because it introduces a reference to ../Application Data, which folder  
is not accessible.
but, i have to find out more about it and eventually start another thread.
