some ARM64 platforms (e.g., NVIDIA Jetson with xhci_hcd), libusb\nreturns LIBUSB_ERROR_NOT_FOUND when attempting to claim the JTAG\ninterface immediately after libusb_open(). This happens because the\ndevice remains in the \"Addressed\" state and the host controller\nrequires an explicit SET_CONFIGURATION before interface resources\nare allocated.\n\nThe CH347F is a single-configuration composite device with\nbConfigurationValue \u003d\u003d 1. Adding libusb_set_configuration(1) before\nthe claim loop makes the driver behave consistently across x86_64\nand ARM64 without affecting existing functionality.\n\nTested on:\n- x86_64 (Ubuntu 24.04.4, kernel 6.17.0-23-generic) - regression verified\n- aarch64 (Jetson, Ubuntu 22.04.4, kernel 5.15.136-tegra) - previously\n  failed, now passes JTAG scan_chain successfully\n\nChange-Id: Ic98eaf7e1099ce4156cc8cabf0c26dcce392d605\nSigned-off-by: Jonah Liu \u003cliujiahan@gmail.com\u003e\n"}}},"requirements":[],"submit_records":[{"rule_name":"gerrit~DefaultSubmitRule","status":"NOT_READY","labels":[{"label":"Verified","status":"OK","applied_by":{"_account_id":1000014,"name":"jenkins","username":"jenkins","tags":["SERVICE_USER"]}},{"label":"Code-Review","status":"NEED"}]}],"submit_requirements":[{"name":"Verified","status":"SATISFIED","is_legacy":true,"submittability_expression_result":{"expression":"label:Verified\u003dMAX -label:Verified\u003dMIN","fulfilled":true,"status":"PASS","passing_atoms":["label:Verified\u003dMAX","-label:Verified\u003dMIN"],"failing_atoms":[]}},{"name":"Code-Review","status":"UNSATISFIED","is_legacy":true,"submittability_expression_result":{"expression":"label:Code-Review\u003dMAX -label:Code-Review\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Code-Review\u003dMAX","-label:Code-Review\u003dMIN"]}}]}
