>Description:
mobile# camcontrol inquiry da8
pass0: <Sony Storage Media 2.51> Removable Direct Access SCSI-0 device
pass0: Serial Number u
pass0: 650KB/s transfers
mobile# usbdevs -v
Controller /dev/usb0:
addr 1: self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
port 1 powered
port 2 addr 2: power 94 mA, config 1, USB Storage Media(0x0010), Sony(0x08ec), rev 2.00
Manufacturer is Sony (but probably OEMs from MSYSTEMS),
model USM128.
I've done considerable work testing the need for the quirk entry,
I'm not going to include it all here. The quirk entry is only
wildcarded for the rev. The first to items are exact. The
6->10 hack code in umass does not seem to be sufficient so
the quirk contains both DA_Q_NO_SYNC_CACHE and DA_Q_NO_6_BYTE.
Both 6-byte c ommands and any attempt to synchronizing the
cache locks up the unit.
>How-To-Repeat:
Plug in one of these devices :-)
>Fix:
Quirk entry patch as shown below, in combination with additional
fixes to USB not included.
