Has anyone experienced any compatibility issues when using certain USB flash drives with the SP3? My SP3 sometimes does not recognize my 32gb Transcend USB flash drive and I have to keep inserting and removing it until it finally recognizes it. However it usually recognizes my 8gb Sandisk USB flash drive. Normally I would just think that there is something wrong with my Transcend flash drive but my desktop computer never has any issues recognizing it. Is the SP3 USB drive just more sensitive? Has anyone else experienced any compatibility issues with flash drives?
