UQ_MSC_DYMO_EJECT: ejects after HID command 0x1b5a01

See /sys/dev/usb/quirk/usb_quirk.h or run "usbconfig dump_quirk_names" for the complete list of supported quirks.

LOADER TUNABLE

The following tunable can be set at the loader(8) prompt before booting the kernel, or stored in loader.conf(5).

hw.usb.quirk.%d

The value is a string whose format is:

“VendorId ProductId LowRevision HighRevision UQ_QUIRK,...
”

Installs the quirks UQ_QUIRK,... for all USB devices matching VendorId and ProductId which have a hardware revision between and including LowRevision and HighRevision.

VendorId, ProductId, LowRevision and HighRevision are all 16 bits numbers which can be decimal or hexadecimal based.

A maximum of 100 variables hw.usb.quirk.0, .1, ..., .99 can be defined.

If a matching entry is found in the kernel's internal quirks table, it is replaced by the new definition.

Else a new entry is created given that the quirk table is not full.

The kernel iterates over the hw.usb.quirk.N variables starting at N = 0 and stops at N = 99 or the first non-existing one.

EXAMPLES

After attaching a u3g device which appears as a USB device on ugen0.3:

usbconfig -d ugen0.3 add_quirk UQ_MSC_EJECT_WAIT

Enable a Holtec/Keep Out F85 gaming keyboard on ugen1.4:

usbconfig -d ugen1.4 add_quirk UQ_KBD_BOOTPROTO

To install a quirk at boot time, place one or several lines like the following in loader.conf(5):

hw.usb.quirk.0="0x04d9 0xfa50 0 0xffff UQ_KBD_IGNORE"

HISTORY

The usb_quirk module appeared in FreeBSD 8.0, and was written by Hans Petter Selasky <hselasky@FreeBSD.org>. This manual page was written by Nick Hibma <n_hibma@FreeBSD.org>.
