'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
