Subject: usb-storage: Add 090c:1000 to unusal-devs
From: Hans de Goede <[email protected]>
commit afff07e61a5243e14ee3f0a272a0380cd744a8a3 upstream.
This device gives a bogus answer to get_capacity(16):
[ 8628.278614] scsi 8:0:0:0: Direct-Access USB 2.0 USB Flash Drive 1100
PQ: 0 ANSI: 4
[ 8628.279452] sd 8:0:0:0: Attached scsi generic sg4 type 0
[ 8628.280338] sd 8:0:0:0: [sdd] 35747322042253313 512-byte logical blocks:
(18.3 EB/15.8 EiB)
So set the quirk flag to avoid using get_capacity(16) with it:
[11731.386014] usb-storage 2-1.6:1.0: Quirks match for vid 090c pid 1000: 80000
[11731.386075] scsi9 : usb-storage 2-1.6:1.0
[11731.386172] usbcore: registered new interface driver usb-storage
[11731.386175] USB Mass Storage support registered.
[11732.387394] scsi 9:0:0:0: Direct-Access USB 2.0 USB Flash Drive 1100
PQ: 0 ANSI: 4
[11732.388462] sd 9:0:0:0: Attached scsi generic sg3 type 0
[11732.389432] sd 9:0:0:0: [sdc] 7975296 512-byte logical blocks: (4.08 GB/3.80
GiB)
Which makes the capacity look a lot more sane :)
