I have tried 2 different after-market thumb drives, and neither will fit in any of the 3 USB ports in the back of my Xbox 4 GB 360S. I've only had the Xbox for about 2 months and don't know a great deal about it, however, I am quite computer savvy. Both USB thumb drives only go in about 1/3-1/2 the way inside the port, almost like it wasn't made to fit. Both thumb drives work perfectly fine on my computer, and insert the entire way with very little effort at all. Since my Xbox has only 4GB, I'm trying to utilize the thumb drives to keep the system memory somewhat free.
Can anyone tell me what I'm doing wrong, or is my unit defective somehow? Thanks.
