| Subject: usb: storage: Add quirk for Samsung Fit flash |
| |
| From: Jim Lin <jilin@nvidia.com> |
| |
| commit 86d92f5465958752481269348d474414dccb1552 upstream. |
| |
| Current driver has 240 (USB2.0) and 2048 (USB3.0) as max_sectors, |
| e.g., /sys/bus/scsi/devices/0:0:0:0/max_sectors |
| |
| If data access times out, driver error handling will issue a port |
| reset. |
| Sometimes Samsung Fit (090C:1000) flash disk will not respond to |
| later Set Address or Get Descriptor command. |
| |
| Adding this quirk to limit max_sectors to 64 sectors to avoid issue |
| occurring. |
