https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263783 hendrik@0x00.to changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hendrik@0x00.to --- Comment #12 from hendrik@0x00.to --- Same issue here using a Sierra Wireless EM7565. After some research I actually found a way to "detach" a device using the "set_config 255" flag for usbconfig: > The special value of 255 unconfigures the device, detaching the interface= drivers and reducing the power consumption to minimum, but without going i= nto power saving mode or detaching from the bus. I'm now able to load the kernel module without a crash (kldload if_umb) how= ever no new network interface umb0 is created. "show_ifdrv" also shows no driver attached. usbconfig also provides a "detach_kernel_driver" flag: > Detach kernel driver for the selected interface and USB device. Using this the kernel still crashes. --=20 You are receiving this mail because: You are the assignee for the bug.=
