Hi,

The format is:

usbconfig add_dev_quirk_vplh <vid> <pid> <lo_rev> <hi_rev> <quirk>

vid: VendorID
pid: ProductID

lo_rev: 0
Hi_rev 0xffff

quirk: your quirk UQ_XXX

If the driver shows a disconnect message or attach failure, then I think 
quirks won't help.

Instead of replugging your device, it is sometimes possible to make the device 
available using:

usbconfig -u X -a Y reset

Where X and Y are the ugenX.Y for your root HUB or your device.

You need to be root to execute these commands.
