*USBQuirk

*USBQuirk adds, removes, or lists the quirk flags for the specified vendor/product/device.
Syntax: *USBQuirk <A | R | L> <vendor> <product> <device> <flags>

This is a method to override misbehaviour in USB devices.

<vendor>, <product> and <device> can be seen in the listing generated by the *USBDevInfo command for the device.

The *USBDevices command will tell you the device number to give to the *USBDevInfo command.

The <flags> field is a bitmap of ‘things that don’t work’ as follows (from the header file):

#define UQ_NO_SET_PROTO 0×0001 / cannot handle SET PROTOCOL. /
#define UQ_SWAP_UNICODE 0×0002 / has some Unicode strings swapped. /
