We can use max buffer size obtained from
descriptor.bMaxPacketSize0()instead of 256 in these methods because internally they call controlTransfer on interface #0.This fixes #3 without manipulations with dirvers. Some devices require to use a buffer of size bMaxPacketSize0 only for control transfer.
