Data on 2nd VCP #25

Closed will-t1-Design closed 1 year ago

will-t1-Design commented 1 year ago

I've have an implementation of this with 2 virtual comms ports and a custom HID. I have the HID and 1 VCP working fine. The 2nd VCP only seems to be able to recieve data from the computer and sending fails with USBD always busy. Has this been seen before / confirmed multiple VCPs work for tx and rx? Most likely my issue...

This is on an stmf401, which if I'm right only has 3 in and 3 out end points therefore with 2 vcp and 1 hid I've gone over?
