https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256296 Tomasz "CeDeROM" CEDRO <tomek@cedro.info> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tomek@cedro.info --- Comment #4 from Tomasz "CeDeROM" CEDRO <tomek@cedro.info> --- Hey Sergii, HPS :-)=20 Sergii is it possible to open device again after closing? It should not be possible to transfer to a device that is not opened.. so LIBUSB_ERROR_NO_DE= VICE may indicate that device is not opened and there is nowhere to tranfer to. Asynchronous transfers may be put on some sort of list and close function should verify the list before closing..? Can you verify with the applicatio= n? :-) In order to analyse situation in depth Wireshark can dump the USB traffic. = You may want to compare Linux and FreeBSD behaviour if you suspect (low pobable) problem in the stack :-) --=20 You are receiving this mail because: You are the assignee for the bug.=
