Hai henning:
   I will develop Linux driver for Mustek A3Pro scanner. But I have some 
problem in Usb modules and scanner modules of kernel.
   Here is scanner info and debug info when i attach scanner to PC


  hub.c: new USB device 00:07.2-2, assigned address 2
  usb.c: kmalloc IF c9a31860, numif 1
  usb.c: new device strings: Mfr=1, Product=2, SerialNumber=0

driver.

      bmAttributes        =   02 (Bulk)
      wMaxPacketSize      = 0040
      bInterval           =   00
    Endpoint:

      bInterval           =   00
    Endpoint:

      bDescriptorType     =   05
      bEndpointAddress    =   82 (in)
      bmAttributes        =   03 (Interrupt)
      wMaxPacketSize      = 0001
      bInterval           =   03
usb.c: kusbd: /sbin/hotplug add 2

   Is pipe size  too large ? How to do with that?  

Thanks a lot

Good Lucky
