Comment 55 for bug 61235

Sorry, this patch is already included in Feisty. No previous suggetion helped me. I built some kernels, sooner or later dmesg will complain about lost pages.
We can however add this controller (it's very popular in empty enclosures from Spire, Welland and the like) to unusual_devs.h to minimize chance of data corruption.

UNUSUAL_DEV(0x04b4, 0x6830, 0x0000, 0xffff,
  "Cypress Semiconductor",
  "USB2.0 Storage Device",
  US_SC_DEVICE, US_PR_DEVICE, NULL,
  US_FL_GO_SLOW | US_FL_MAX_SECTORS_64),

I don't know if there are any other revs than 0000, but if anyone knows of working revision, 0xffff could be changed to that.

Perhaps delay different than Genesys GO_SLOW would fix this better. I give up.
