Abstract:
It is an object of the invention to ensure the reliable and flawless operation of a storage means that is connected to a data reproduction system. This object will be met by a method for controlling the admission of a storage means to a peripheral bus of a data reproduction system, wherein a storage means is connected to the peripheral bus of a data reproduction system, the read latency of the storage means is determined, and it is decided based on the determined read latency whether the storage means is admitted to the peripheral bus or rejected. The latency for read requests from the storage means, for instance a USB mass storage device, will be analyzed on first insertion and the results of this analysis will be used to carry out a compatibility check of the storage means with the data reproduction system, for example a car audio system.
