Does this mean that Linux community leaves no choice but to ship a
forked kernel (with no chance of alignment to upstream) for
organizations which design embedded devices where USB plays a key
role, hence requires passing the USB-IF Compliance Program [*]?

Is there hope to give users a knob (build-time or run-time) which would
enable the behavior expected and thoroughly described in compliance
docs, particularly chapter "6.7.22 A-UUT Device No Response for
connection timeout" of "USB On-The-Go and Embedded Host Automated
Compliance Plan" [**]?


Best regards,
Eugeniu Rosca
