![]() from what i can tell, sending port enable is a spec violation. this fixes a hang during hub enumeration in the ASMedia xhci controller when i plug in my IBM UltraNav SK-8845. also, send unsuspend when port is suspended instead of enable. from the USB 2 specification: 11.24.2.7.1.2 PORT_ENABLE ... This bit may be set only as a result of a SetPortFeature(PORT_ENABLE). ... The hub response to a SetPortFeature(PORT_ENABLE) request is not specified. |
