https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225794 --- Comment #44 from Hans Petter Selasky <hselasky@FreeBSD.org> --- Hi, Try also to exclude the timing of the SCSI commands as a source of USB erro= rs. When you are using bare metal, the commands execute more quickly. Sometimes= , it might happen that the USB firmware in the peer has blind eye, which cause i= t to hang or lose the transferred command. The following sysctl might be useful testing this. hw.usb.umass.throttle: 0 Further there is: /usr/src/tools/tools/usbtest/ Which can be used to test mass storage device to quickly reveal known issue= s. --HPS --=20 You are receiving this mail because: You are the assignee for the bug.=
