Research direction

Start by reproducing the USBHOST hub-initialization failure with an affected USB-C dongle and trace the path from the reported setup-stage transaction error to device-descriptor retrieval. Done means the affected dongles initialize successfully without the shown allocation, transaction, or device-attach failures.
