https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231076 --- Comment #9 from Ludovic Rousseau <ludovic.rousseau+freebsd@gmail.com> -= -- When the USB device is removed libusb10_handle_events_sub() will call libusb10_cancel_all_transfer() at https://github.com/freebsd/freebsd/blob/master/lib/libusb/libusb10_io.c#L170 libusb10_cancel_all_transfer() will then call libusb20_tr_close() at https://github.com/freebsd/freebsd/blob/master/lib/libusb/libusb10.c#L1570 libusb20_tr_close() will then reset the variable fields at https://github.com/freebsd/freebsd/blob/master/lib/libusb/libusb20.c#L142 So when libusb_cancel_transfer() is called by my code the fields priv_sc0 a= nd priv_sc1 are already reset to 0 and libusb_cancel_transfer() returns LIBUSB_ERROR_NOT_FOUND in https://github.com/freebsd/freebsd/blob/master/lib/libusb/libusb10.c#L1547 I can test any patch you propose to fix the issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
