Linux: 4.14.0 and 4.15-rc2 SOC: H3 Driver: sun8i-h3-musb I am trying to add 3 functions to a composite gadget and it fails. [ 4.664742] configfs-gadget gadget: acm/23b5a59a: can't bind, err -19 [ 4.671227] configfs-gadget musb-hdrc.1.auto: failed to start g1: -19 The same configuration works on a am335x, and it also works in this SOC when using just 1 or 3 functions, it just fails from 3. Eg: 2x ACM - OK. 1x ACM + 1x Mass Storage works - OK. 3x ACM - ERROR 2x ACM + 1x Mass Storage - ERROR Might this be a SOC limitation in some way? Hints were to start debugging?
