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:
- 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
Maybe we need a quirk table then ?
It seems the list of affected devices is unknown.

Would this impact the USB transfer rate? Frieder, do you know?
