Hi,

I have a strange USB-Stick here. It's some "nano"-4G stick, only slightly
bigger than the actual USB plug.

With usb_storage.delay_use=1, it's found as:

[139787.814139] usb 2-2: new high speed USB device using ehci_hcd and address 26
[139787.929698] usb 2-2: New USB device found, idVendor=14cd, idProduct=125b
[139787.929706] usb 2-2: New USB device strings: Mfr=1, Product=3, 
SerialNumber=2

[139787.930263] scsi23 : usb-storage 2-2:1.0
[139789.842530] scsi 23:0:0:0: Direct-Access     Intenso  Micro Line   PQ: 0 
ANSI: 0 CCS
[139789.842802] sd 23:0:0:0: Attached scsi generic sg1 type 0
[139790.090805] sd 23:0:0:0: [sdb] 8054783 512-byte logical blocks: (4.12 
GB/3.83 GiB)

and everything is fine.

With usb_storage.delay_use=5 (which is default in vanilla kernel AFAICS),
it is found as:

[140044.180139] usb 2-2: new high speed USB device using ehci_hcd and address 27
[140044.295636] usb 2-2: New USB device found, idVendor=14cd, idProduct=125b

[140044.295655] usb 2-2: Manufacturer: Intenso
[140044.295660] usb 2-2: SerialNumber: 000000000021
[140044.296327] scsi24 : usb-storage 2-2:1.0
[140049.296759] scsi 24:0:0:0: Direct-Access-RBC                       PQ: 2 
ANSI: 4
[140049.296943] scsi 24:0:0:0: Attached scsi generic sg1 type 14

and it does not work.

Now even if it works by accident with a SUSE kernel, I'm still interested
in why it is so strange. Is this a bug to report on LKML?
