Hello All, Does anyone have details/reasoning on the following: Why the protocol code is set 00 in IAD and it's set to 01 in ACM control interface descriptor in f_acm.c file? Shouldn't IAD be the same as in ACM control interface descriptor? Due to this in windows, we are unable to install the modem(ACM) driver based on class-subclass-protocol matching. The windows compatible IDs is showing the IAD class-subclass-protocol codes for ACM.
