The passthrough path was fake-completing zero-length bulk/interrupt IN URBs to mirror the emulated path, so games that drain-poll between transfers wouldn't stall the libusb worker thread. This baked an emulator-side assumption about device behaviour into the host stack. Real PS3 USIO devices issue a ZLP on the read endpoint after any transfer that would otherwise leave the host's drain URB outstanding (notably after a CMD_WRITE). Devices that follow the same protocol (e.g. ITAIKO firmware) are expected to do the same; faking it here masks firmware bugs and diverges from real hardware behaviour. Drop the workaround and let libusb submit the URB normally. The IN URB now completes when the device sends its ZLP, matching real PS3.
