Dear all,
Sorry!
1. Is it correct that IOUSBDEVICE_FUNCS_180, 182 and 183 denote version of
USB? (USB Spec I use describes USB 1.1, is it what would be 110 in the above
or it is a different novel?). I don't ask about IOUSBINTERFACE_FUNCS_XXX
hoping of the same meaning of their _XXX. Or is it just "version of
DeviceInterface and InterfaceInterface functions?
2. Is there a way (other than trying to access ID183 first, on failure
trying ID182 and finally ID180 if all else fails) to determine at runtime
what version of these functions is available to my application? I could of
course check for system version, that is the reason for the third question
3. So far I know that 1.8 corresponds to 10.0, 1.8.1 corresponds to
10.0.1...
Is it correct that 1.8.2 is available in 10.0.2, 1.8.3 in 10.0.3 and so on?
Does it mean that routines from 1.8.2 should be absolutely OK if the user
lives under 10.1 or higher? (I need something from the 182, so in case if
the system does not know ID182, I might inform the user that the application
is compatible with, say, 10.0.2 or higher.)
Thanks in advance
Oleg
PS By the way, "hotblack" asked few days ago a question I was about to ask.
Thanks to those who replied... And special thanks to hotblack for saving my
keyboard and fingers from excessive wear! Just imagine: I got immediate and
very useful response!
