Hi Matthew,
I pulled you name from the kernel maintainers file to let someone know about a quirk that I discovered with an MP3 player that connects as usb-storage. Hope I've got this right.
When I connected it to my fedora 8/14/16 machine ( sorry not the latest kernel ) it didn't work. The following is the dmesg output:
[ 1703.287204] usb 2-1: new high speed USB device using ehci_hcd and address 4 [ 1703.402018] usb 2-1: New USB device found, idVendor=1e74, idProduct=4641 [ 1703.402025] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1703.402030] usb 2-1: Product: USB [ 1703.402034] usb 2-1: Manufacturer: [ 1703.402037] usb 2-1: SerialNumber: USBV1.00 [ 1703.402840] scsi5 : usb-storage 2-1:1.0 [ 1704.403915] scsi 5:0:0:0: Direct-Access USB DISK 1.00 PQ: 0 ANSI: 0 [ 1704.409525] sd 5:0:0:0: Attached scsi generic sg3 type 0 [ 1704.411604] sd 5:0:0:0: [sdc] 15958016 512-byte logical blocks: (8.17 GB/7.60 GiB) [ 1704.514300] usb 2-1: reset high speed USB device using ehci_hcd and address 4 [ 1709.628307] usb 2-1: device descriptor read/all, error -110 [ 1709.730154] usb 2-1: reset high speed USB device using ehci_hcd and address 4 ....
So I played around with the usb-storage parameter quirks, and found that 1e74:4641:rw worked a treat. Hope this is helpful.
For all the others googling for this : Dick Smith Electronics MP3 player 8GB DSE A8705 add kernel command line parameter usb-storage.quirks=1e74:4641:rw
