freebsd 9 - help for unrecognized usb disks
noticed this behavior on fbsd 9, dunno whether it affects other versions…
some new usb sticks are buggy, only tested with ms windows timings. if freebsd doesn’t recognize a usb disk (usb stick), the following quirk may help.
- get the usb unit and address of the device
-
plug in the device and do:
dmesg | egrep -A5 '^ugen|^umass' | tail
note the line that starts with ugen, e.g. ugen1.2
-
use the unit.addr obtained in the following
usbconfigcommand: -
usbconfig -d <unit.addr> add_quirk UQ_MSC_NO_INQUIRY
- example:
-
usbconfig -d 1.2 add_quirk UQ_MSC_NO_INQUIRY - unplug, then plug in the device, and do:
dmesg | taildevice should be recognized…
