At the moment I have two sticks with the same chip around for which 
setting USB_MAX_XFER_BLK from 65535 to 32767 fixed the file transfer.
Also one of our customers tested a few non-working sticks with this 
change and reported, that it fixed it for him.
Here's a list of those devices, but I guess there are a lot more:

1. Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) Flash 
Drive, VID: 0x090c, PID: 0x1000
2. Freecom Technologies, VID: 0x07ab, PID: 0xfcf1
3. Newron, VID: 0x8644, PID: 0x800e
4. GEMBIRD PhotoFrame PF-15-1, VID:  0x1908, PID: 0x1320
