Hi,

When you see "failed" in the log that means a SCSI command failed. To me it looks like the following command failed:

#define PREVENT_ALLOW           0x1e

Can you find more failed commands ?

Isn't this brand supposed to be super-fast ?

By inserting a line of code, you can make the USB transfer execution go slower. It doesn't look like that is the problem.
