'lsusb -v' will show the class of the device:

    Interface Descriptor:
      bLength                 9
      bDescriptorType         4
      bInterfaceNumber        0
      bAlternateSetting       0
      bNumEndpoints           3
      bInterfaceClass         8 Mass Storage
      bInterfaceSubClass      6 SCSI
      bInterfaceProtocol     80 Bulk (Zip)
      iInterface              0 

If it isn't a Mass Storage class usb device you need to create a
manual mapping of vendor/device (0451/6250 in your case) to have
hotplug map it to the usb-storage driver.

This will tell hotplug to load the usb-storage module when that device
is discovered.  You can manually modprobe usb-storage to see if that
helps.

I'm not to familiar with suse, but you need to find one of hte mapping
files usually under /etc/hotplug or /etc/hotplug/usb and add an entry
mapping the vendor/device to the usb-storage driver.

I can never remember what all the fields are but something like:

usb-storage 0x000f 0x0451 0x6250 0x0 0x0 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
