    USB: usblp.c - add Kyocera Mita FS 820 to list of "quirky" printers
    
    This patch gets the Kyocera FS-820 working with cups 1.2 via usb again. It
    adds the printer to the list of "quirky" printers. The printer seems not
    answer to ID requests some seconds after plugging in. Patch is based on
    linux-2.6.19.1.
    
    Background:
    As far as I could see (strace, usbmon), the Kyocera FS-820 answers to ID
    requests only a few seconds after plugging it in. This applies to detecting
    it with cups and is also true for the printing itself, which is initiated
    with an ID request. Since I have little usb knowledge, maybe someone can
    interpret the data, especially the fist bulk transfer - why request 8192
    bytes? This is the second version of the patch.
