Device is considered isochronous if one of its endpoints is
defined as isochronous transfer, in that case data transfer
over the usbredir channel will not be compressed
(it is assumed that there is a strong correlation between
isochronous devices and devices which their data is usually
compressed)

E.g.
Camera/mic device will usually be recognised as isochronous
while storage devices won't
