Analyze and fix the following issue in the Linux kernel code: USB: OHCI handles more ZFMicro quirks
Problem Details: The ZF Micro OHCI controller exhibits unexpected behavior that seems to be related to high load. Under certain conditions, the controller will complete a TD, remove it from the endpoint's queue, and fail to add it to the donelist. This causes the endpoint to appear to stop responding. Worse, if the de...
