Transcend JetFlash V85

[Volodymyr Kostyrko]

Hi people.

Just recently saw the message on STABLE:

MFC r210931:
Disable sync cache for the Transcend Jetflash V90.

This sounds good since I have the same problem with my JetFlash V85:
Aug 19 23:33:55 limbo kernel: (da4:umass-sim1:1:0:0): SYNCHRONIZE 
CACHE(10). CDB: 35 0 0 0 0 0 0 0 0 0
Aug 19 23:33:55 limbo kernel: (da4:umass-sim1:1:0:0): CAM status: SCSI 
Status Error
Aug 19 23:33:55 limbo kernel: (da4:umass-sim1:1:0:0): SCSI status: Check 
Condition
Aug 19 23:33:55 limbo kernel: (da4:umass-sim1:1:0:0): SCSI sense: 
ILLEGAL REQUEST asc:26,0 (Invalid field in parameter list)

My flash looks like:
ugen3.3: <Mass Storage Device JetFlash> at usbus3, cfg=0 md=HOST 
spd=HIGH (480Mbps) pwr=ON

   bLength = 0x0012
   bDescriptorType = 0x0001
   bcdUSB = 0x0200
   bDeviceClass = 0x0000
   bDeviceSubClass = 0x0000
   bDeviceProtocol = 0x0000
   bMaxPacketSize0 = 0x0040
   idVendor = 0x058f
   idProduct = 0x6387
   bcdDevice = 0x0100
   iManufacturer = 0x0001  <JetFlash>
   iProduct = 0x0002  <Mass Storage Device>
   iSerialNumber = 0x0003  <SZR04MNI>
   bNumConfigurations = 0x0001

Can someone help me understanding how can I a a quirk for my flash drive?
