Subject: [PATCH] usb-storage: Add quirk for ScanLogic SL11R-IDE older than 2.6c
Date: Mon, 13 Sep 2021 23:01:06 +0200 [thread overview]
Message-ID: <20210913210106.12717-1-linux@zary.sk> (raw)
ScanLogic SL11R-IDE with firmware older than 2.6c (the latest one) has
broken tag handling, preventing the device from working at all:
usb 1-1: new full-speed USB device number 2 using uhci_hcd
usb 1-1: New USB device found, idVendor=04ce, idProduct=0002, bcdDevice= 2.60
usb 1-1: New USB device strings: Mfr=1, Product=1, SerialNumber=0
usb 1-1: Product: USB Device
usb 1-1: Manufacturer: USB Device
usb-storage 1-1:1.0: USB Mass Storage device detected
scsi host2: usb-storage 1-1:1.0
usbcore: registered new interface driver usb-storage
usb 1-1: reset full-speed USB device number 2 using uhci_hcd
usb 1-1: reset full-speed USB device number 2 using uhci_hcd
usb 1-1: reset full-speed USB device number 2 using uhci_hcd
usb 1-1: reset full-speed USB device number 2 using uhci_hcd
Add US_FL_BULK_IGNORE_TAG to fix it. Also update my e-mail address.
2.6c is the only firmware that claims Linux compatibility.
The firmware can be upgraded using ezotgdbg utility:
